give short note on plant excretion
Answers
Answer:
Excretion is the removal of substances from plants, animals and other living organisms. In humans, the skin, lungs and kidneys are excretory organs.
Answer:
Excretion is carried out by plants in the following ways:
1) The gaseous wastes oxygen, CO2 and water vapour are removed through the stomata of leaves and lenticels of stems
2) Some waste products gets collected in leaves and barks of trees
3) when the leaves and barks are shed, the wastes are eliminated
Explanation:
Plants have no special organs for removal of waste. The waste products of respiration and photosynthesis are used as raw material for each other. Oxygen gas produced as a by-product of photosynthesis is used up in respiration and carbon dioxide produced in respiration is used up during photosynthesis.
