Calculating Mitotic Index using Plant Cells (AQA A-Level Biology): Flashcards

Proportion of cells actively undergoing mitosis in a tissue sample

Growth regions where plant cells actively divide

Shoot and root tips

Totipotent - can differentiate into any cell type

60°C

Softens tissue by breaking down cell walls and middle lamella

Binds to DNA, makes chromosomes visible during mitosis

$\frac{\text{cells with visible chromosomes}}{\text{total cells}}$

At least 500 cells

Active mitosis (cell division)
