B. Potato

Explanation:

The catalase is an enzyme which can be seen in all living organisms which are exposed to the action of oxygen. It's function is to catalyze the decomposition of hydrogen peroxide into water and oxygen. This enzyme is protective against the oxidative damage caused to the cells of the organisms.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
