Question

Cleavage is a unique form of mitotic cell division in that ______.

Options

• the nucleus does not participate

• no spindle develops to guide the chromosomes

• the plasma membranes of daughter cells do not separate

• there is no growth of cells

Answer 1

Cleavage is a unique form of mitotic cell division in that there is no growth of cells.

Explanation:

Cleavage is a unique form of mitotic cell division because it increases the number of cells without any growth in the overall size of the embryo. The cells become progressively smaller after each division, but the total volume remains the same. This distinguishes cleavage from typical mitotic divisions where the cell usually grows between divisions.
