PATHOLOGY

Detailed explanation-1: -A cell grows during the G1 phase of the cell cycle. During this phase, more organelles are produced, a high amount of protein synthesis occurs and the volume of the cytoplasm increases. The cell continues to grow further in the G2 phase.

Detailed explanation-2: -Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.

Detailed explanation-3: -During the G1 phase, the cell grows in size and produces new proteins. G1 is followed by S phase during which new chromosomes are synthesized.

Detailed explanation-4: -The cell cycle is a 4-stage process consisting of Gap 1 (G1), synthesis (S), Gap 2 (G2), and mitosis (M), which a cell undergoes as it grows and divides. After completing the cycle it either starts the process again from G1 or exits through G0.
