Plants use completely different strategies for excretion than those of animals. Oxygen itself can be thought of
as a waste product generated during photosynthesis. They can get rid of excess water by transpiration. For
other wastes, plants use the fact that many of their tissues consist of dead cells, and that they can even lose
some parts such as leaves. Many plant waste products are stored in cellular vacuoles. Waste products may be
stored in leaves that fall off. Other waste products are stored as resins and gums, especially in old xylem. Plants
also excrete some waste substances into the soil around them.
a) What are the waste products of plants?
b) Why leaves of plant fall off?
c) In which process Oxygen is a waste product for plant?
d) What is transpiration?
Answers
Answer:
a) What are the waste products of plants?
Ans) Plants need to excrete excess carbon dioxide and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis
b) Why leaves of plant fall off?
Ans) Overwatering and underwatering can cause a plant to lose leaves. Either too much or too little water will affect the structure of the plant. When a plant receives too much water, the water floods the leaves, because it has nowhere else to go. ... Very dry, brown leaves are a sign your plant is lacking moisture.
c) In which process Oxygen is a waste product for plant?
Ans) photosynthesis
Plants need to excrete excess carbon dioxide and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis .
d) What is transpiration?
Ans) the process water passing out from the surface of a plant or leaf.
