Plant cell walls are mainly composed of cellulose. Cellulose is a different kind of sugar that is classified as a structural carbohydrate that is not used by plant cell for energy. The cellulose protects the organelles that are found inside the plant cell. They serve as a protective layer of the cell and they provide its shape and support. In other plant organisms, they are the secondary walls of the plant cell that increases the rigidity of the cell and they serve as the waterproofing mechanism of plant cells; an example of this are the wood and bark cells of trees.
Answer:
Less.
Explanation:
Its contractile vacuole become less active because of the same concentration of water in both the body and outside environment. Contractile vacuole is responsible for the removal of excess liquid with the help of contraction. In isotonic environment, there is no flow water occur inside or outside of the cell due to the presence of equal amount water in both the environment i. e. cell and outside environment so due to equal amount of water, contractile vacuole become less active.

Explanation:
The difference in structure and function of different ribosome types is continually being researched and amended, but there are currently two ways in which they can be classified. The first way is to classify them based on the kind of cell they inhabit: archaeal, eukaryotic, or eubacterial. The organelles in these specific types of cells differ in composition, size, and protein to ribonucleic acid (RNA) ratio. The second way in which ribosomes are classified involves whether they are bound to a membrane or remain free-floating within the cell. The terms used to describe this classification are “membrane-bound” and “free,” respectively.
