How does cell division differ between animal and plant cells?
The cell plate is the final partitioning of plant cells
Cell division is a process by which a single cell divides into two or more daughter cells. There are two types of cell division: mitosis and meiosis. Mitosis is the process of cell division that occurs in somatic or non-reproductive cells, while meiosis is the type of cell division that occurs in reproductive or gamete cells. The process of cell division differs between animal and plant cells in the following ways:
1. Cell Wall: Animal cells do not have a cell wall, while plant cells have a rigid cell wall made of cellulose. During cell division, the cell wall of a plant cell must break down and reform, while animal cells do not require this process.
2. Centrosomes: Animal cells have a pair of centrosomes, which are important structures that organize the microtubules during mitosis. Plant cells do not have centrosomes, but instead, they have spindle microtubules that form from the microtubule organizing centers.
3. Cytokinesis: In animal cells, cytokinesis occurs by a process called cleavage, where a cleavage furrow forms and pinches the cell in two. In contrast, plant cells form a cell plate across the center of the cell, which eventually becomes the cell wall.
4. Chromosome formation: The chromosome formation in animal and plant cells is slightly different. Animal cells have a pair of centrioles that assist in the formation of spindle fibers during cell division. Plant cells do not have centrioles, and the spindle fibers are formed from the microtubules of the plant cell.
In conclusion, the process of cell division differs between animal and plant cells due to the presence of cell wall, centrosomes, cytokinesis, and chromosome formation. These differences reflect the unique characteristics and functions of these two types of cells.
