Detailed explanation-1: -The cellular respiration, photosynthesis, and other metabolic reactions produce a lot of excretory products in plants. Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants.
Detailed explanation-2: -Excretion is carried out in the plants in the following ways: The gaseous wastes, oxygen, carbon dioxide, and water vapor are removed through the stomata of leaves and lenticels of stems. Some waste products collect in the leaves and bark of trees. When the leaves and bark are shed, the wastes are eliminated.
Detailed explanation-3: -When old leaves fall, the waste materials are excreted along with the leaves. Removal of carbondioxide and oxygen as waste products during respiration and photosynthesis also takes place in leaves with through stomatal pores. Leaves are also responsible for the removal of extra water by transpiration.
Detailed explanation-4: -They are: Ammonotelism (Type of excretion-ammonia) Ureotelism (Type of excretion – urea) Uricotelism (Type of excretion – uric acid)
