Class X Practical: Plant Life - Microscopy (Mitosis Stages)

Objective

To observe and identify different stages of mitosis from permanent slides.

Microscope Setup: Place the permanent slide of mitosis stages on the microscope stage. Start with the lowest power objective lens.
Focusing: Adjust the coarse and fine adjustment knobs to bring the cells into clear focus.
Scanning: Systematically scan the slide to locate cells undergoing different stages of mitosis (prophase, metaphase, anaphase, telophase).
High Power Observation: Once a mitotic stage is located, switch to a higher power objective lens for detailed observation.
Identification: Identify the characteristic features of each stage:
- Prophase: Chromosomes condense, nuclear envelope disappears.
- Metaphase: Chromosomes align at the metaphase plate.
- Anaphase: Sister chromatids separate and move to opposite poles.
- Telophase: Chromosomes decondense, nuclear envelopes reform, cytokinesis begins.
Drawing: Draw neat, labeled diagrams of each identified mitotic stage.

Ability to recognize and differentiate between the various stages of cell division (mitosis) in plant cells from prepared slides.
