Question

What are the two reasons why cells divide?

Answer 1

Hint: Cell division is the process in which a parent cell divides to form two or more daughter cells. It takes place via the cell cycle and keeps the cell division in a place. Due to cell division, the growth and development of an individual occur.

Complete answer:
Growth, reproduction, ability to sense the environment, and suitable response against something all are counted as unique features of living organisms. They also help in various metabolism processes, have the ability to replicate and organize on their own, and may interact, and emerge on their own. The cell division and enlargement of the cell results in the plant growth. Before the cell division starts the cell enlargement takes place. This results in an increase in the number and mass of an individual resulting in its growth. Multicellular organisms grow by cell division. The plants grow throughout their life due to the continuous process of cell division.
The cell cycle includes various events and stages that prepare the cell for division and includes four stages. In the G1 also called gap 1 stage the increase in cell size occurs, then the S stage takes place where the DNA is replicated and lastly the G2 stage also called gap 2 stage occurs where the cell prepares itself for the cell division. After this, the mitotic or M2 phase occurs where the cell division takes place. Various genes are responsible for the process of cell division and cell growth. Cells replicate themselves in an organized manner and step-by-step fashion during the cell cycle and ensure that the dividing cells i.e DNA are copied properly or not, any errors found, or replication occurs correctly or not.
-The cell division is very important because of the following reasons-
1) For the survival and growth of organisms.
2) Maintaining chromosome numbers.
3) Damaged cells renewable

Note:
In 1835, a German botanist Hugo von Mohl first discovered the cell division under the microscope in the alga Cladophora. The cell division includes Prophase (the first stage of division). The chromatin then condenses and results in the formation of the chromosomes. Metaphase (the second stage of division), where the at the equator chromosomes are arranged, then occurs Anaphase where at the poles the chromosomes are arranged and lastly Telophase stage in which the cell divides into two daughter cells by forming a cell plate in between.
