Question

Main function of pneumatophores is
A. Respiration
B. Photosynthesis
C. Transpiration
D. None of the above

Answer 1

Hint: Pneumatophores is the process that occurs in some plants in which many roots come out of the ground and start growing vertically upwards. And these processes are found in the mangroves and in swampy areas like Rhizophora and modification to get oxygen for the respiration. In this the aerial roots that help the plant’s to breathe in the air.

Complete answer:
Rhizophora Avicenna is the breathing roots present in the pneumatophores. And respiration that is also known as respiration roots modification of the pneumatophores function, also found in the water clogged soul and in the marshy areas. The production of the tap roots underground the soil and come above the soil in the form of dry, brownish conical roots.
Myrtles are the breathing roots present in the pneumatophores and portion grow upward till they project some centimeters above and low tide level on the surface of the soil. Lenticels are the small opening that helps to reach the air in other parts of the plant roots. And angiosperms are present in the mangroves root system and play the same role as the pneumatophores in the mud flats and saline water. And this plant is the example of root diversity because the lateral roots that grow upward for varying distance and function of the site oxygen intake for the submerged primary roots.

Therefore the correct option is (A).

Note: The roots grow into the down from the stem and up from the typical rots in. the habitats which have waterlogged soil. The roots take up air into the plant tissues with the process of osmosis pathways and deliver oxygen throughout the plant as needed in the lenticels that present on the surface.
