Answer and Explanation:
The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.

Answer:
3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.
Explanation:
4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.
