Answer 1

The correct answer is Stomata

Key Points

Stomata are small openings found in the epidermis of leaves, stems, and other organs that are involved in the process of transpiration and gaseous exchange.
They play a crucial role in regulating water loss and facilitating the exchange of gases such as oxygen and carbon dioxide between the plant and the atmosphere.
Each stoma is flanked by two specialized cells known as guard cells which control the opening and closing of the stomatal pore.
Stomatal density and behavior can vary depending on environmental conditions such as light, humidity, and carbon dioxide concentration.

Additional Information

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems, and flowers.
Stomata also play a role in photosynthesis by allowing the uptake of carbon dioxide necessary for the process.
The opening and closing of stomata are influenced by factors such as light intensity, carbon dioxide levels, internal water balance, and circadian rhythms.
Stomata are typically more numerous on the underside of leaves to minimize water loss due to direct sunlight.
