Question

Where are the waste products stored in the plants?
A. In plant cell
B. In cytoplasm
C. In phloem cell
D. In cellular vacuoles

Answer 1

Hint: Plants excreted the main waste products like carbon dioxide, water vapour and oxygen through gaseous exchange through stomata and lenticels. Some wastes are stored in plants in the form of gums and resins.

Complete Answer:
- The plants like animals also excrete the waste. The gases wastes can be eliminated through gaseous exchange. The water which is in excess can be removed through transpiration. There are certain metabolic ions and molecules which are also present in excess and need to be get rid of. In the plant cell all the metabolic activities are carried out. This activity also generates waste after the utilisation, assimilation and reabsorption.
- The plant cells have a specialised structure called the large vacuoles whose main function is to store waste, food, nutrients. It is also the store house of lipids, carbohydrates and proteins.
- Cytoplasm: Cytoplasm is the part of the cell in which all the organelles are present. It acts as a medium for exchange of molecules between the organelles.
- Phloem: It is the connective tissue through which food and other nutrients are transported to various parts of the plant.

Thus the correct answer is (D).

Note: The storage organelles of the cells are called the vacuoles. These are membrane bound organelles which are composed of phospholipid. It encloses cell sap. Cell sap contains food, wastes, and other biomolecules.
