Preparation and Apparatus00:00:29
Overview of necessary apparatus including onions, acetocarmine stain, spirit lamp, and various tools. Explains the fixation process using acetic acid, methanol, and hydrochloric acid to stop cells in their current mitotic stage.
Heating and Staining00:03:38
Heating the root tips in hydrochloric acid at 60°C to prepare the tissue, followed by washing in distilled water and staining with acetocarmine to make the structures visible under a microscope.
Slide Mounting and Squashing00:08:17
Technique for mounting the root tip on a slide, avoiding air bubbles with a coverslip, and using a rubber-headed pencil to squash the tissue, ensuring individual cells are separated for observation.
Microscopic Observation of Mitosis00:11:37
Final observation under a light microscope to identify different stages of mitosis, including prophase, metaphase, and anaphase, based on chromosome arrangement.
