Explanation:

Cell wall biosynthesis begins during cell division in the cytokinesis phase through the formation of the cell plate in the middle of the cell. Eventually, the primary cell wall is assembled by the deposition of polymers of cellulose, hemicelluloses and pectin.

Answer 2

Answer:

1. Cell wall biosynthesis begins during cell division in the cytokinesis phase through the formation of the cell plate in the middle of the cell. Eventually, the primary cell wall is assembled by the deposition of polymers of cellulose, hemicelluloses and pectin.
2. Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones .
