Correct the statement and if necessary rewrite.

a) The cell wall is essential in plant cells.

b) The nucleus controls cell activity

c) Unicellular organisms perform all life processes like respiration, excretion, growth,

and reproduction.

Answer :

From the above-given statements it can be inferred that (a),(b),(c) are correct statements where as the statements (d) is incorrect. The staining process is an auxiliary process in which the stains are added to the cells so that they components of the cell can be easily visualized and it gives a good contrast with the background.

Thus the correct statement for (d) is that we have to do staining ignorer to see the nucleus and the cell organelles easily.
