How does mitosis in plants differ from mitosis in animals?

Answer 1

"In animal cells, the cell membrane pinches in the middle and the cytoplasm divides. In plant cells, the appearance of a cell plate shows that the cytoplasm is being separated." - Glencoe Science Book 7th Grade "Life Science"

The above refers to the division of the cytoplasm, which is called cytokinesis. Although cytokinesis accompanies mitosis, it is not strictly part of it; mitosis is nuclear division.

In animal cells there is an organelle, the centriole, which is not found in plants. The centriole divides in two during prophase, and each daughter-centriole moves to a position that will be one pole of the spindle.

However, the centriole is not essential for mitosis in animal cells, and plant cells do not have one.

The term "microtubule organizing center" (MTOC) is used for any structure that forms the spindle. It is not yet clear what the MTOC is in plants.

Answer 2

1. There are no centrioles in a plant cell whereas they are present in animal cells.

2. In cytokinesis, the final step of mitosis, a cell's cytoplasm separates in half with each half containing one nucleus. An animal cell membrane pinches in, creating a cleavage furrow until the mother cell is pinched in half. In plant cells, a new cell wall is constructed at what was the midline of the mother cell.

3. In plant cell during telophase, phragmoplast (acting myosin microtubules) forms in centre of cell where as in animal cell contractile ring forms approximately midway between the 2 nuclei of the dividing cell.

4. Plant cell has a cell wall & animal cell lacks it 5. In plant cell nuclear and cell division found in special regions called meristems where as in animal cell divides everywhere, all the time.

Answer 3

Mitosis in plants is typically more variable in terms of timing and duration compared to animals. In plants, cell plate formation occurs during cytokinesis to divide the cell, while animals form a cleavage furrow. Additionally, plants have a rigid cell wall that needs to be taken into account during cell division, which is not a consideration in animal cell division.

Answer 4

In the last step of mitosis, plant cells form a cell wall... and animal cells don't. That's all.

Answer 5

Plant cells lack centrioles.

Answer 6

plant mitosis differ from animal mitosis

Answer 7

plant cells lack centrioles.
