NEET Biology question
Cells X and Y underwent mitosis but marked differences were observed in the way they divided. Cell X did not change shape prior to mitosis but cell Y did. Spindles formed during division were anastral in cell X but amphiastral in cell Y. Identify cell X and cell Y.
Answer: (B)
Solution
An anastral spindle (lacking asters) forms in plant cells, which lack centrioles; a rigid cell wall also means a plant cell does not change shape before dividing. An amphiastral spindle (with asters at both poles) forms in animal cells, which have centrioles; animal cells, bounded only by a flexible plasma
