Question

The aquatic plants can be prevented from being carried away by water currents
due to the presence of
a) Long , narrow stems b) Air chambers in stem
c) Waxy covering d) Narrow or tiny leaves

Answer 1

Aquatic plants have a firm hold of the aqautic floor by their roots. Also, most plants like kelp; maybe having long leaves or long stems, are saved from being flown away due to more surface area.

So, aquatic plants are not flown away by currents due to their long leaves or stems.

Answer 2

The correct answer for the given question is: Long, narrow stems (option a)

• Aquatic plants have evolved particular adaptations to help them thrive in the water:

1. The aquatic plants' long, narrow stems aid in preserving flexibility during the flow of strong water currents, allowing them to bend freely yet not be carried away or destroyed by water.
2. The plant's floating capacity is enabled via air chambers in the stem.
3. The waxy layer protects the leaves from rotting.
4. Narrow, small leaves also help with flotation and damage resistance.

• As a result, the aquatic plants' narrow and long stems prevent them from being carried away by water currents.
