The main difference between dividing an animal and plant cell lies in
1 Cell plate formation
2 Chromosome movement
3 Disapperance of nucleolus, ER, GB
4 Chromosome separation
Explanation:
Animal cell performs cytokinesis by appearance of furrow in the plasma membrane. Plant cells divide by the formation of a cell plate due to the presence of an inextensible cell wall.

Mitotic stages are not observed in:
1 Cosmarium
2 E. coli
3 Saccharomyces
4 Chlorella
Explanation:
E.coli is bacterium and it undergoes Binary fission and does not show mitotic or Meiotic type of cell division..

Mitosis helps
1 Replacement of old cells
2 Repair
3 Restore the nucleo-cytoplasmic ratio
4 All of these
Explanation:
The growth of multicellular organisms is due to mitosis. Cell growth results in disturbing the ratio between the nucleus and the cytoplasm. It therefore becomes essential for the cell to divide via mitosis to restore the nucleo-cytoplasmic ratio. Mitosis also contributes in cell repair by replacing old, dead cells with new ones.

Cell which divides by mitosis is
1 Upper layer of epidermis
2 Cells lining gut
3 Somatic cells
4 All of these
Explanation:
Mitosis contributes in cell repair. The cells of the upper layer of the epidermis, cells of the lining of the gut, and blood cells are constantly replaced by mitosis. Mitotic divisions in the meristematic tissues – the apical and the lateral cambium, result in a continuous growth of plants.
