Aerenchyma cells are present in ____________.

Correct option is A

Sol: The correct answer is (a) common water hyacinth

key points:

• ​Aerenchyma cells are specialized parenchyma cells found in aquatic plants. These cells have large air spaces that facilitate the exchange of gases (like oxygen) between the plant and its environment. This adaptation is particularly important for plants growing in waterlogged or aquatic environments.
• ​Common Water Hyacinth (Eichhornia crassipes): This aquatic plant has aerenchyma cells that help it float and survive in waterlogged conditions by allowing efficient gas exchange.

Information booster:

• Pea (Pisum sativum): Pea plants are terrestrial and do not have aerenchyma cells.
• Cactus (Family Cactaceae): Cacti are adapted to arid environments and do not have aerenchyma cells.
• Neem (Azadirachta indica): Neem trees are terrestrial and also do not possess aerenchyma cells.
