Question

Why is transport of materials necessary in a plant or in an animal? Explain.

Answer 1

• Transport of materials is necessary in both plants and animals, as every cell needs a regular supply of nutrients and oxygen to release energy through respiration.
• The food that we eat is broken down into smaller components to be absorbed by the cells. The oxygen that we inhale is also transported to all the cells of the body.
• In plants and animals, food, water, oxygen and other important useful substances are transported to various parts of the body through blood through which a human being performs biological activities.
• Through transportation, harmful substances produced in those organs, such as carbon dioxide, sweat, urine, etc., are removed from the body. Therefore, the transportation of substances is necessary for plants and animals.
