Question

products ?
v. Explain why aquatic plants have very short and small roots.
​

Answer 1

Answer:

The waste products of a plant are carbon dioxide, water vapour and oxygen. While carbon dioxide and water vapour are waste products of respiration, oxygen is a waste product of photosynthesis. These waste products are removed through stomata in leaves and lenticels in stems and are released into the air.

5 Aquatic plants have less rigid structure since water pressure supports them. . Since they need to float, leaves on the surface of plants are flat. ... Their roots are smaller so water can spread freely and directly into the leaves.
