MICROANATOMY

Detailed explanation-1: -Because of this, animal cells can bend their cell membrane inward and perform cytokinesis “from the outside in” by forming a cleavage furrow. A cleavage furrow is an indentation on the cell surface that continuously deepens until the animal cell is “pinched” into two separate halves.

Detailed explanation-2: -A ring of protein filaments called the contractile ring forms around the equator of the cell just beneath the plasma membrane. The contractile ring shrinks at the equator of the cell, pinching the plasma membrane inward, and forming what is called a cleavage furrow.

Detailed explanation-3: -The daughter cells enter the cell cycle in G1. When cytokinesis finishes, we end up with two new cells, each with a complete set of chromosomes identical to those of the mother cell.
