The main parts of a cell which are involved in the cell division are:
- Nucleus – It is the control centre of the cell. …
- Centrioles – Centrioles are present in the animal cells. …
- Microtubules – They help in aligning and separating the chromosomes during the metaphase and anaphase stages of cell division.
What do you mean by reproduction in biology?
Biology Facts. Cell reproduction is the process by which cells divide to form new cells. Each time a cell divides, it makes a copy of all of its chromosomes, which are tightly coiled strands of DNA, the genetic material that holds the instructions for all life, and sends an identical copy to the new cell that is created.
How does cell reproduction work in humans?
Cell Reproduction. As chromosomes vary in size, one human chromosome can hold genetic information equivalent to the amound ot genetic information in many chromosomes from another organism. A chromosomes consists of two halves, called Chromatids. These halves are divided in their center by a centromere.
What is the role of chromosomes in cell reproduction?
Cell Reproduction. These chromosomes determine the gender of the organism. (A male has an X and a Y, while a female has to Xs). In addition, all the chromosomes in an organism excluding the sex chromosomes are part of a homologous pair. They contain genes to control the same traits but the genes do not have the same instructions.
What happens when a cell divides into two new cells?
Each time a cell divides, it makes a copy of all of its chromosomes, which are tightly coiled strands of DNA, the genetic material that holds the instructions for all life, and sends an identical copy to the new cell that is created. This is a process called Mitosis, and can be found in greater detail by following the link.
