AP Biology Lab 3: Mitosis and Meiosis

Mr. Anderson introduces AP Biology Lab 3, focusing on mitosis and meiosis. The lab involves observing onion root cells to study mitosis and Sordaria fungus to understand meiosis and genetic crossover. Mitosis is described as the equal division of a diploid cell's nucleus, resulting in identical cells. Meiosis involves two divisions and crossing over, producing genetically unique haploid cells. The lab uses techniques to observe cell phases and calculate genetic crossover, providing insights into gene mapping.

What does the term 'haploid' mean in the context of meiosis?

What are meristems and how are they related to plant growth?

How can we determine the time cells spend in each phase of mitosis?
