Question

A cell shows formation of a contractile ring just prior to cytoplasmic division.

Which cell is being observed?
A. Onion root tip cell
B. Leaf cell
C. Human fetal cell

Answer 1

Human fetal cell

Step-by-step explanation:

The contractile ring is formed in the cytoplasmic plain. This ring gradually constricts and helps in the separation of daughter cells. The contractile ring is found in the animal cell division i.e. during cytokinesis. In plant cells, the cytoplasm divides by the cell plates. Later this cell plate forms the cell wall of the daughter cells. Here onion root tip cells and leaf cells are plant cells. Therefore no contractile ring is found in them. So the correct answer is the human fetal cell.

Answer 2

If a cell shows formation of a contractile ring just prior to cytoplasmic division, the cell that is being observed is C. human fetal cell.
