In what ways is the cell cycle similar in plant and animal cells, and in what ways does it differ?

Identify the phases of the cell cycle: Both plant and animal cells undergo the cell cycle which includes the phases G1 (cell growth), S (DNA synthesis), G2 (preparation for mitosis), and M (mitosis and cytokinesis).
Examine mitosis: During mitosis, both plant and animal cells undergo prophase, metaphase, anaphase, and telophase, where chromosomes are aligned, separated, and moved to opposite poles of the cell.
Explore cytokinesis differences: In animal cells, cytokinesis occurs through the formation of a cleavage furrow that pinches the cell into two. In plant cells, cytokinesis occurs through the formation of a cell plate that eventually develops into a new cell wall, dividing the cell into two.
Consider the role of organelles: In plant cells, the presence of a rigid cell wall, chloroplasts, and a large central vacuole affect various aspects of the cell cycle, including the positioning and process of cytokinesis.
Analyze cell cycle regulation: Both plant and animal cells regulate the cell cycle through similar mechanisms involving cyclins and cyclin-dependent kinases (CDKs), but specific regulatory proteins might vary between the two.
