The diagram given below represents a stage of the cell division. Is it a plant cell or an animal cell? Give a logical reason.

The diagram shows the anaphase stage of mitosis in which the chromosomes move towards the poles. The cell is a plant cell as it has a cell wall and cell plate. The cell wall is a rigid wall made up of cellulose which surrounds the plasma membrane. The cell plate is formed at the midpoint between the two groups of chromosomes in a dividing plant cell. In the diagram, labelling 3 represents a cell plate. These are not found in animal cells. The centrioles are not found in the diagram. It is found only in an animal cell. Hence, the above diagram is a plant cell.

The diagram given below represents a stage of the cell division. Label the parts 1 to 4.

The above diagram showing the anaphase stage of the mitosis. The centromere splits and the chromosomes move towards the poles. The spindle fibres are attached to the centromere of the chromosomes. The cell plate is formed in the middle of the cell.

The given diagram represents a certain phenomenon which occurs during meiosis. State the difference between chromosomes and chromatid.

Characteristic Chromosome Chromatid Structure Chromosomes are the thick rod-like structures bearing genes, present in the nucleus. Each half of the duplicated chromosome is called chromatid. These are the two identical halves of a chromosome.
