I hope this helps you
mark me as brainiest
a. Cell wall is present only in animal cells. False
Cell wall is present only in plant cell not in animal cell as plants require this additional layer of protection around the cell membrane. Plant cells require protection from extremes in temperature, wind speed, and other factors. Because they are unable to move, they are subjected to these changes.
Animal cells do not have cell walls because they make cells hard and reduce cell flexibility, which makes it difficult for animals to move. Organisms' locomotive capacity is limited by cell walls.
b. Cell wall is made of cellulose. True
The cell wall is made up of a network of cellulose molecules and cross-linking glycans embedded in a matrix of cellulose polysaccharides that is cross-linked.
c. Prokaryotic cells do not have a nuclear membrane around the nucleus.True
A nucleus is not present in a prokaryotic cell. There is no nuclear membrane in the nucleus. Cell organelles such as Golgi bodies and the endoplasmic reticulum are also absent. The prokaryotes have been assigned to the kingdom Monera.
