Question

how is water lettuce adapted to grow in water?​

Answer 1

Answer:

Tiny hairs on the roots and leaves unable the water lettuce to float , making sure that it does not drown in its watery environment... it's leaves are waxy , which makes water run of more easily . this is an essential quantity as the plant is floating aquatic and not a submerged one

Answer 2

Answer:

• Tiny hairs on the roots and leaves enable the water lettuce to float, making sure that it does not drown in its watery environment.
• The shape, a kind of rosette, resembles that of a cup, which is another adaption allowing it to float.

Explanation:

• Aquatic plants are those that grow in or on water.
• Floating plants, fixed plants, and submerged plants are the three kinds of aquatic plants.
• Duckweed, water lettuce (Pistia stratiotes), and water hyacinth are light and spongy floating plants. This makes plants exceedingly light. As a result, plants may float on the water's surface. To resist water, leaves have a waxy top surface.
• For its aquatic habitat, Pistia has evolved a number of buoyancy adaptations:-
• Pistia stratiotes plants float freely across the water surface, resembling loose-leafed lettuce.
• Roots that have been finely split float in the water under floating rosettes of corrugated, spongy leaves with air-filled chambers that keep the plant afloat.
• A thick coating of minute, water-repellent hairs covers the velvety leaves as well.
• The plant is difficult to sink due to air trapped between the hairs on the leaf surface, which gives the vibrant-green leaves a silvery aspect.
