AP Biology Investigation No. 7: Cell Division: Mitosis and Meiosis

Description

Students will study the cellular steps involved in DNA replication and cell division in both mitosis and meiosis. This investigation will allow students to examine the stages of mitosis in the preparation of plant root tips. Crossing over in meiosis will also be investigated through the use of Sordaria cultures. Meets AP Science Practices 1, 5, 6, and 7, and Big Idea 3. Materials provided for 32 students in eight lab groups.
