NEET BIOLOGY

Detailed explanation-1: -Centrosome is the region present adjacent the nucleus and in cytoplasm which contain centrioles. It is present only in animal cells. It is also called as microtubule organising centre of the cell. Centrosome helps in cell division in animal cells.

Detailed explanation-2: -Centrioles are located near the nucleus and help organize cell division. Centrioles are not found in plant cells. Microtubules build cilia and flagella, which enable cells to move.

Detailed explanation-3: -Centrioles are present in (1) animal cells and (2) the basal region of cilia and flagella in animals and lower plants (e.g. chlamydomonas). In cilia and flagella centrioles are called ‘basal bodies’ but the two can be considered inter-convertible. Centrioles are absent from the cells of higher plants.

Detailed explanation-4: -Centrioles are present only in animal cells and in some lower plant cells. In all higher plant cells, centrioles are absent.

Detailed explanation-5: -Centrioles. Centrioles are organelles involved in cell division. The function of centrioles is to help organize the chromosomes before cell division occurs so that each daughter cell has the correct number of chromosomes after the cell divides. Centrioles are found only in animal cells and are located near the nucleus.
