The two reasons why cell divides are:
- Growth.
- Replacing damaged or dead cells.
What are the three 3 main reasons cells divide?
What are the three 3 main reasons cells divide?
- Food, Waste, and Gas Exchange. They need to maintain a workable ratio of surface area to volume to allow an efficient transfer of materials in and out of the cell.
- Growth. In order for an organism to grow, they must divide so they can get larger.
- Repair.
- Reproduction.
Why is it so important that cells divide correctly?
Multiplication of cells or cell division is an asexual and continuous process. It is essential for a cell to divide primarily for the life form to grow and to repair its wounds and injuries, but also another reason why cell division occurs is that without cell division, a life form cannot function.
What are two reasons why cells may stop dividing?
They sometimes stop dividing when they’re damaged, however, which can contribute to the transformation of normal cells into cancer cells and is believed to play a role in the aging process. Now scientists have a better understanding of how this breakdown occurs.
Why do cells need to undergo division?
Two reasons cells must divide: 1. To grow in size (number of cells increase through cell division) 2. Repair dead or lost cells (cells need to replace other cells through cell division) Reason single- celled organisms undergo cell division To reproduce (make more cells) Asexual reproduction

What are the two main reasons cells divide rather than to continue growing?
The larger the cell, the more demands the cell places on its DNA. 2. The cell has trouble moving enough nutrients and wastes across the cell membrane.
What are 2 reasons cells divide?
Cells divide for two reasons:Growth. We all started out as a single cell; the fusion of a sperm from dad and an egg from mom. ... Repair. Cells are constantly wearing out and getting damaged, and unless an organism replaces them at least as fast as they are lost, a gradual deterioration will occur.
What are the two ways cells divide?
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
What are 4 reasons that cells divide?
MatchFood, Waste, and Gas Exchange. They need to maintain a workable ratio of surface area to volume to allow an efficient transfer of materials in and out of the cell.Growth. In order for an organism to grow, they must divide so they can get larger.Repair. ... Reproduction.
Why do cells divide 3 reasons?
Cell division is central to organism growth, reproduction and tissue repair.
What is the process by which a cell divides into two new daughter cells?
The process by which a cell divides into two new daughter cells is called cell division
Why are cells limited in size?
size of cells is limited because food, water, oxygen and waste enter and leave through the cell membrane - that's why cells divide instead of grow becuase if they get bigger and bigger, they can't get enough food in or waste out - it's the relationship between a cell's volume and its surface area
What happens when chromosomes are repilcated?
chromosomes are repilcated and the synthesis of DNA molecules takes place
What is the first division of the cell nucleus?
1st - division of the cell nucleus - mitosis, 2nd - division of the cytoplasm - cytokinesis
How many identical chromosomes are in a cell before cell division?
well before cell division, each chromosome is replicated or copied, because of this, each chromosome consists of 2 identical
What does a cell replicate?
the cell replicates or copies all of its DNA
How many daughter cells are there in a cell?
a cell grows, prepares for division and divides into 2 daughter cells, each of which then begins the cycle again
