#CLASS12thBIOPRACTICAL#MITOSIS IN ONION ROOT TIPS @BP(BIOLOGY )#CANVAS

An onion root tip is a rapidly growing part of the onion and thus many cells will be in different stages of mitosis. The onion root tips can be prepared and squashed in a way that allows them to be flattened on a microscopic slide, so that the chromosomes of individual cells can be observed easily. During the process of mitosis, the chromosomes pass through several stages known as prophase, metaphase, anaphase and telophase. Acetocarmine stain is used to colour the chromosomes
