Apical meristem is present in which of the following? 

The correct answer is Plants.

Key Points

• Apical meristems are regions of actively dividing cells in plants, found at the tips of roots and shoots.
• They are responsible for primary growth, which increases the length of the plant.
• Apical meristems give rise to various tissues and organs of a plant.
• These meristems help in the elongation of roots and shoots, aiding in the plant's ability to reach light and absorb nutrients.

Additional Information

• Meristematic Tissue:
  • Meristematic tissues are regions in plants where cells are continuously dividing.
  • These tissues are found in zones of the plant where growth can take place, such as the tips of stems and roots.
• Types of Meristems:
  • Apical Meristem: Located at the tips of roots and shoots, responsible for primary growth.
  • Lateral Meristem: Found along the sides of stems and roots, responsible for secondary growth, increasing the thickness.
• Primary Growth vs. Secondary Growth:
  • Primary Growth: Involves the elongation of the plant body, facilitated by apical meristems.
  • Secondary Growth: Involves the thickening of the plant body, facilitated by lateral meristems such as the vascular cambium and cork cambium.
• Role of Apical Meristems:
  • They are crucial for the formation of new leaves and flowers.
  • They help the plant in adapting to its environment by growing towards light and water sources.
