Cytology Science

The branch of science which deals with the study of form,structure and functions of cell is called cytology science.The cytology science also gives the behaviours of nucleus and other organelles.Cytology science enables for the origion and discovery of cells.Mainly cytology sience formulates the cell theory.The body of organism is made up of cells and their products.Both the structure and function of living organisms is called cell.Life passes from one generation to another generation in the form of living cells.Different types of the cells in the body does work in organisms.According to the cytology science various cells of the body are independent.The cytology science divides the cell into two parts.They are plant cell and animal cell. Plant cell:The plant cell is covered by cell wall.Plant cell has a definite form because of presence of cell wall.Generally chromosomes are absent in the plant cell.The plant cell contains green chloroplasts and plastids.Typical lysosomes are generally absent.Glyoxysomes occurs in the same plant cell.A mature types of plant cell contains single central vacuoles. Animal cell:The animal cell is not covered by cell wall.The animal cell has not definite form due to the absence of cell wall.Specially chromosomes are present in the animal cell.The animal cell do not contain chloroplasts and plastids.Typical lysosomes are generally present in the animal cell.Glyoxysomes does not occur in the same animal cell. Behaviours of nucleus: The nucleus is bounded by protoplasmic body which controls cellular metabolism and transmission.In outline the nucleus is of elliptical shape.Mainly nucleus consists of-
