Question

Unlike prokaryotes, all eukaryotic cells are not identical. Justify the statement.

Accepted Answer

All eukaryotic cells (such as plant cells and animal cells) are not identical because centrioles are found in animal cells, but these are absent in plant cells. There are several other differences between plant and animal cells, such as the presence of a cell wall in plant cells, the presence of chloroplasts in plant cells, and the shape of their respective vacuoles. It is also important to note that the absence of centrioles in plant cells does not necessarily mean that they are unable to undergo cell division. Plant cells and animal cells can still divide through the process of mitosis, which is a type of cell division that occurs in eukaryotic cells to produce two identical daughter cells.

In contrast, prokaryotes divide through a process called binary fission, which is a form of asexual reproduction that involves the splitting of one cell into two identical daughter cells. Prokaryotes lack a true nucleus and membrane-bound organelles, so they do not undergo mitosis. Instead, their genetic material is replicated and distributed to each daughter cell during binary fission.
