Show Answer
Ans.(d)
Sol. Insects require oxygen to live and produce carbon dioxide as a waste product just as we do. They do not have lungs nor do they transport oxygen through their circulatory systems. Instead, insects use a series of tubes called a tracheal system to perform oxygen exchange throughout the body.

Ans.(b)
Sol. A plant cell is different from animal cell mainly on the basis of the cell wall. The outer shell in a plant cell (which is made from cellulose in green plants) is known as cell wall, which is not found in the animal cell. Except this, green plastids are also found in plant while not in animal cells.
