The Correct Answer is Option 2 i.e Epithelial Tissue.

Key Points

• Adipose Tissue:
  • The tissue that stores all the fat of the human body is called 'adipose tissue'. 
  • It is a loose connective tissue composed of adipocytes.
• Epithelial Tissue:
  • They cover all the outer surfaces of the body.
  • They are the first line of protection from any physical or chemical damage.
  • The outermost layer of the skin, the epidermis is an example of this tissue.
• Muscular tissue:
  • It is a soft tissue that connects the muscles of the body and has the ability to shorten or contract in order to produce movement of the body parts.
• Areolar tissue:
  • It is loose connective tissue. 
  • It acts as a reservoir of water and salts for surrounding tissues.

The correct answer is Muscle cells.

Key Points

• Muscle cells, also known as muscle fibers, are responsible for the contraction and relaxation that results in the movement of organs and the body.
• There are three types of muscle cells: skeletal, cardiac, and smooth muscles, each with specific functions in the body.
• Skeletal muscles are attached to bones and are involved in voluntary movements such as walking and lifting.
• Cardiac muscles are found in the heart and are responsible for pumping blood throughout the body.
• Smooth muscles are found in organs such as the intestines and blood vessels, and they control involuntary movements like the digestion process and regulation of blood flow.

Additional Information

• Myofibrils:
  • Myofibrils are the basic rod-like units of a muscle cell that are composed of repeating sections called sarcomeres, which are the contractile units.
  • Each myofibril contains thick (myosin) and thin (actin) filaments that slide past each other to produce muscle contraction.
• Neuromuscular Junction:
  • The neuromuscular junction is the synapse or connection between a motor neuron and a muscle fiber.
  • It is where the nervous system communicates with muscles to trigger contraction through the release of neurotransmitters like acetylcholine.
• ATP and Muscle Contraction:
  • Adenosine triphosphate (ATP) is the energy currency of the cell, and its hydrolysis provides the energy needed for muscle contraction.
  • Muscle contraction occurs when ATP binds to myosin, allowing it to interact with actin and produce a power stroke.
• Muscle Tone:
  • Muscle tone refers to the continuous and passive partial contraction of muscles, which helps maintain posture and ensures muscles are ready for action.
  • It is regulated by the nervous system and is essential for maintaining balance and coordinating movements.

The correct answer is Ligaments

Explanation:

• Ligaments are a type of connective tissue that connect one bone to another bone, providing stability and support to joints.
• They are composed mainly of long, stringy collagen fibers which provide great tensile strength.
• Ligaments are crucial for maintaining the structural integrity of the skeletal system, especially in joints where they help to prevent excessive movements that could lead to dislocation or injury.
  • Tendons: Tendons are connective tissues that attach muscles to bones, not bones to bones. They play a key role in transmitting the force generated by muscles to the bones, enabling movement.
  • Areolar tissue: Areolar tissue is a loose connective tissue that holds organs in place and attaches epithelial tissue to other underlying tissues. It also surrounds blood vessels and nerves. It does not connect bones to each other.
  • Cartilage: Cartilage is a flexible connective tissue found in various forms in the body, such as in the joints between bones (as articular cartilage), the rib cage, the ear, the nose, and the bronchial tubes. It provides support and flexibility but does not directly connect bones to each other.

The correct answer is Muscular tissue.

Key Points

• Muscular tissue is responsible for the movement of the body and its parts.
• There are three types of muscular tissue: skeletal, cardiac, and smooth muscle.
• Skeletal muscles are attached to bones and cause voluntary movements.
• Cardiac muscle tissue is found only in the heart and is responsible for pumping blood throughout the body.
• Smooth muscle tissue is found in walls of internal organs such as the stomach, intestines, and blood vessels and is responsible for involuntary movements.

Additional Information

• Nervous tissue
  • Nervous tissue is responsible for transmitting nerve impulses and is found in the brain, spinal cord, and nerves.
  • It plays a crucial role in controlling and coordinating body activities.
• Epithelial tissue
  • Epithelial tissue forms the lining of internal and external surfaces of the body, including skin and the lining of organs.
  • It provides protection and is involved in absorption, secretion, and sensation.
• Connective tissue
  • Connective tissue supports, binds, and protects other tissues and organs.
  • It includes bone, cartilage, adipose tissue, and blood.

• Blood from the ventricle travels to the lungs and skin where it is oxygenated and also to the body.
• In the ventricle, deoxygenated and oxygenated blood are mixed before being pumped out of the heart.

The correct answer is Intercellular spaces are present.

Key Points

• The characteristic features of permanent tissue are:
  • Cells have intercellular spaces to keep them separated.
  • The cells may be living or dead, i.e.the protoplasm is either present or absent.
  • Tissue may have only one type of cell or may have different kinds of cells.
  • The cell wall is either cellulosic or along with cellulose other complex carbohydrates may be present.
  • Cells may vary in shape, i.e., either round or oval or polygonal, etc.
  • In the living cells, the cytoplasm is present surrounding a large central vacuole.
  • Cells do not divide at all.

Additional Information

• Types of permanent tissue: 
• Permanent tissues are of three types, namely –
  • (a) Simple tissue, (b) Complex tissue and (c) Secretory tissue.
• ​Simple permanent tissue
  • Simple permanent tissue is composed of a single type of cells that have comparable origin, structure, and function.
• Types of simple permanent tissue
  • Parenchyma – It  provides temporary support and maintains the shape of the plant body. They have thin-walled cells with large vacuoles.
  • Collenchyma – It provides mechanical support and elasticity and flexibility to young dicotyledonous plants. They have thickened cell walls at corners, giving mechanical strength.
  • Sclerenchyma – It provides strength and toughness to plant parts. They have dead cells with extremely thick walls (lignin deposition). Sclerenchyma may be either fibres or sclereids
• Complex permanent tissue
  • Complex permanent tissue is composed of two or more two types of cells and contributes to a general function.
  • They organize together to carry out similar particular functions in the plant body.
  • It is also known as vascular tissue.
• Types of complex tissue:
  • Xylem – The xylem tissue is accountable for the transmission of water and minerals from the roots to the leaves and stems.
  • Phloem – This complex permanent tissue helps in the translocation of food that is prepared by photosynthesis in the leaves to diverse parts of the plant.

• These are involuntary in nature and are also found in the tracts of the urinary, respiratory and reproductive systems.
• These muscles also play an important role in the ducts of exocrine glands.

The correct answer is Adipose tissue.

Concept:

• Multicellular organisms have an organization of similar cells that perform a specific function, these are called tissues.
• Cells present in a tissue may not be exactly similar in structure and functions but all of them are similar in origin. 
• The word Animal tissue was coined by Bichat.
• The study of tissue is called Histology.
• Based on the structure and functions tissue can be grouped into four categories.

1. Epithelium/Epithelial Tissue
2. Connective Tissue 
3. Muscular TIssue
4. Nervous Tissue

Explanation:

• Adipose Tissue is a specialized type of connective tissue.
• These tissues have oval-shaped cells called adipocytes which are present below the skin surface WHite adipose tissue - present in and stores lipids or fats.
• The fat collected is in the form of a fat globule.
• Based on the morphology adipose tissue is of two types

1. White adipose tissue - present in adults
2. Brown adipose tissue - present in infants.

Additional Information

• Areolar connective tissue is the most widely distributed tissue present in the body, it provides a support framework for epithelium.
• Muscular tissue is responsible for the movement of multicellular organisms 

The correct answer is Insects.

Key Points

• All living organisms respire to get energy from food.
• The process of breakdown of food in the cell with the release of energy is called cellular respiration.
• A network of tubes called tracheae are the respiratory organs of insects.
• Tracheal tubes help insects to transport atmospheric air within the body.
• Oxygenated air rushes through spiracles into the tracheal tubes, diffuses into the body tissue, and reaches the body cell.
• Carbon dioxide from the cells moves to the tracheal tubes and moves out through spiracles.

Additional Information

• Reptiles, birds, and mammals respire through the lungs.
• Amphibians like frogs can respire through their moist skin.
• Earthworms breathe through their moist skins(cuticle).
• Fishes use gills for gas exchange.
• Mussels breathe through their gills.

The correct answer is Epithelial tissue.

Key Points

• Epithelial tissue is a protective tissue in the animal body.
• Epithelial tissue is one of the four primary forms of bodily tissue that may be found in human organs and covers both internal and external surfaces.
• Depending on where it resides in the human body, it has a variety of structures and functions.
• The epithelium is a type of body tissue that covers all of your internal and external body surfaces, lines body cavities and hollow organs, and is the main tissue in glands.
• Protection, secretion, and absorption are all roles of epithelial tissue, depending on where it's positioned in the human body.
• Epithelial cells make up epithelial tissue.

Important Points

• Muscle tissue is made up of cells with the unique capacity to shorten or contract in order to move the body's parts.
• The brain, spinal cord, and nerves all include nerve tissue. It is in charge of coordinating and controlling various bodily functions.
• Connective tissue also stores fat, aids in the transportation of nutrients and other substances between tissues and organs, and aids in the repair of damaged tissue. 

The correct option is 4 i.e Areolar.

• ​There are four types of tissues in animals: connective, muscle, nervous, and epithelial.
• Areolar connective tissue is found beneath the dermis layer and is also underneath the epithelial tissue of all the body system that have an external opening.
• Muscle tissue is a soft tissue that composes muscle in animal bodies and gives rise to muscle's ability to contract.
• Connective tissue is another type of animal tissue found in between other tissues everywhere in the body including the nervous system.
• Epithelial tissue forms the covering of all body surfaces, line body cavities and hollow organs.

The correct answer is Option 1, i.e Adipocyte.

Explanation:

• Adipocytes, also known as lipocytes and fat cells, are the cells that primarily compose adipose tissue, specialized in storing energy as fat.
  • Lying three layers deep under the skin, the adipose tissue is composed of a loose collection of specialized cells, called adipocytes, embedded in a mesh of collagen fibres.
• Chondrocytes:  They are the only cells found in healthy cartilage.
  • They produce and maintain the cartilaginous matrix
• Osteocytes form osteoblasts, and are bone-forming cells.
