Question

There are lots of air spaces in the stem of the cactus.

• A. True
• B. False

Answer 1

The correct option is B False

Desert adaptation in plants:

1. The leaves of plants such as cactus growing in deserts are reduced to a needle-like structure known as spines which helps to reduce the rate of transpiration and thus loss of water.

Aquatic adaptation in plants:

1. The plants growing in water such as lotus, water hyacinth, etc have poorly developed root systems, stems are highly porous and filled with air and leaves are broad to keep the plant afloat over the surface of the water.

Final answer: The given statement is false.
