Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.

How are photosynthesis and cellular respiration different?

kari74 [83]

Answer:

The correct answer is B photosynthesis stores energy,while cellular respiration releases energy.

Explanation:

Photosynthesis is an anabolic process that utilizes the atmospheric CO2 along with water molecule as a electron donor to generate glucose sugar and oxygen gas.Photosynthesis helps to store the light energy in form of chemical energy in the bonds of glucose molecules produced during photosynthesis..

on the other hand cellular respiration is a catabolic process that oxidizes glucose to generate energy in form of ATP along with CO2 and water as a byproduct.
