The function of lenticels is

  • A) to receive excess water in the plant
  • B) to absorb water from the atmosphere
  • C) for gaseous exchange
  • D) to absorb light

Correct Answer: C) for gaseous exchange

Explanation

Lenticels are small pores found on the surface of stems and roots that allow gases to enter and exit the plant. The function of lenticels is called gaseous exchange, and it helps the plant to obtain the carbon dioxide it needs for photosynthesis and release the oxygen it produces. This process is essential for the plant's survival. Option A is incorrect because lenticels do not receive excess water in the plant. Instead, they allow gases to enter and exit the plant. Option B is also incorrect because lenticels do not absorb water from the atmosphere. They only allow gases to enter and exit the plant. Option D is also incorrect because lenticels do not absorb light. In summary, the function of lenticels is to allow for gaseous exchange, which is important for the survival of the plant. It helps the plant obtain the carbon dioxide it needs for photosynthesis and release the oxygen it produces.
