NEET BIOLOGY

Detailed explanation-1: -Answer and Explanation: Plant cell division is unique due to the presence of the cell wall and the lack of centrioles. Plant cells go through a process called cytokinesis, which is when the cellular material is divided.

Detailed explanation-2: -Land plants have an anastral mitotic spindle that forms in the absence of centrosomes, and a cytokinetic apparatus comprised of a predictive preprophase band (PPB) before mitosis and a phragmoplast after mitosis.

Detailed explanation-3: -Centrioles are absent from the cells of higher plants. When animal cells undergo mitosis they are considered by some to benefit from the presence of centrioles which appear to control spindle fibre formation and which later has an effect on chromosome separation.

Detailed explanation-4: -Spindle formation is delayed. Chromosomes have instability. Thus, mitosis becomes asymmetric.

Detailed explanation-5: -Why do plant cells not have centrioles? and they do not require centrioles. Animal cells need centrioles to pull the parent cells into two new daughter cells whereas in plant cells the cytoplasm spreads and a new cell wall is formed in the center that leads to the formation of two new cells.
