Question

label each phase of the cell cycle below.

1. which statement most accurately compares mitotic cell division in plant and animal cells?

a. it is exactly the same in plant and animal cells.
b. the walls of plant cells pinch in, but the membranes of animal cells do not.
c. most plant cells use centrioles, but most animal cells do not.
d. in both plant and animal cells, the daughter cells are genetically identical to the original cell

Explanation:

• Option a: Mitotic cell division is not exactly the same in plant and animal cells. For example, in cytokinesis, plant cells form a cell plate while animal cells form a cleavage furrow.
• Option b: In cytokinesis, it is the membranes of animal cells that pinch in (cleavage furrow formation), and plant cells form a cell plate (due to their cell walls).
• Option c: Most animal cells have centrioles which play a role in spindle - fiber formation during mitosis, while most plant cells do not have centrioles.
• Option d: Mitosis is a process of asexual reproduction (in the context of single - celled organisms) or growth and repair (in multicellular organisms). In both plant and animal cells, the daughter cells produced by mitosis have the same genetic material as the parent cell (assuming no mutations during DNA replication).

Answer:

D. In both plant and animal cells, the daughter cells are genetically identical to the original cell.
