Featured in PASCO’s College Biology Instructor Guide
College Instructor edition with 26 experiments covering introductory and general biology topics.
Mitosis and Meiosis
Use a microscope and prepared slides to explore the stages of mitosis and meiosis.
Students investigate the processes of mitosis and meiosis by:
- Stating and recognizing the stages of cell division.
- Distinguishing between nuclear division and cytokinesis.
- Differentiating between plant and animal cytokinesis.
- Comparing and contrasting mitosis and meiosis.
Students gain experience conducting the following procedures:
- Observing prepared onion root tip and whitefish blastula slides under a microscope.
- Calculating the relative amount of time for each stage of mitosis.
- Simulating the stages of meiosis.
- Estimating the percentage of crossing over that occurs between the centromere and the gene that controls spore color in Sordaria.
- Observing the arrangement of ascospores in the asci of an organism resulting from a cross between a wild-type and a mutant (for tan spore coat color) Sordaria.
Sensors / Equipment Used:
