In mitosis cell division a cell divides into two and two cells divide into four cells and the process continues. But if this control is lost due to any reason, cell division continuous in an irregular way. This is called irregular cell division. Cancer, tumour etc. complicated diseases are the result of irregular cell division.
At the time of the development of reproductive cells, number of chromosomes becomes half than that of theĀ mother cell. This situation is known as haploid. When the haploid cells are fused, the state of cell having two sets of chromosomes is called diploid.
Mitosis is termed as equational division. Mitosis is a type of cell division by which a eukaryotic cell divides into two by a special method. In this process, the nucleus and chromosome are divided once and the number, structure and properties of chromosome in the newly formed cell remain just alike the mother cell.
A prokaryotic cell does not contain any true nucleus. This is why it is called a cell with a primitive type of nucleus.
The parenchyma cells with air filled spaces are called aerenchyma, that usually found in the aquatic plants.
The organelle that lacks membrane aroundĀ it helps in protein synthesis of animal and plant is called Ribosome.
Growing from the mesoderm of the embryo the particular type of contracting and expanding tissue forming the muscles of vertebrae animals is called muscular tissue.
Every living body is composed of cells. Some living bodies are made of only one cell. They are called unicellular organisms, e.g. bacteria, amoeba, plasmodium, some fungi, and some algae, some living bodies are made of more than one cell. These are called multicellular organisms. There are many living bodies, which are made of millions … Read more
