Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Cytokinesis is the process of the cell cycle which divides the cytoplasm of the parent cell into two cells.
The process of cytokinesis involves the membrane of the cell, so the process differs in plant and animals cell as the plant cell exhibits two layers that are the cell wall surrounding the plasma membrane while animal cell lacks the cell wall. the main difference in both the process is:
1. Plant cell division-occurs by cell plate formation while animal cell division- occurs by full cleavage.
2. In-Plant cell- no cytoskeleton is involved while in animal cell- Cytoskeleton components are actively involved
3. Plant cell division is centripetal while animal cell division is centrifugal
4. Plant cell-wall formation is present while animal cell-Wall formation is absent
The similarities in both the process are that it generates the genetically identical daughter cells. In both cells, cytokinesis after the karyokinesis and is the last stage of the division.

1. FtsZ tubulin homolog
2. actin and tubulin
3. actin and tubulin
4. b. animals and bacteria
Explanation:
1. In bacteria, the binary fission process takes place when the cytoskeletal structure of the bacteria are assembled to form the contractile ring in the centre of the cell. The contractile ring in bacteria is composed of the Z-protein which is a tubulin homolog.
2. Plants: the plants divide by the cell plate formation and not the contractile ring formation. This is mediated by the actin, tubulin and vesicle produced from the dictyosomes.
3. Animals: a contractile ring attached to the plasma membrane is formed which is composed of the F-actin and tubulin.
4. Since the bacteria and animal cytokinesis involves the formation of the contractile ring and thus the same mechanism of cytokinesis.
