Cell Growth and Division
In this biology worksheet, 9th graders label the diagrams with the appropriate phase of mitosis illustrated. Then they explain why skin cell undergo mitosis continuously. Students also explain why mitosis is a form of asexual reproduction.
Curated OER
Meiosis, Gene Linkage and Maps
Students identify the structures that actually assort independently. They are taught how gene maps are produced. Students compare the processes of mitosis and meiosis. They are shown their (mitosis and meiosis) significane to sexual...
Curated OER
Sexual Versus Asexual Reproduction
Students discuss the prefix "a" as in atypical and abiotic. They coy definitions of sexual and asexual reproduction into their notes. Students use prior knowledge of mitosis, meiosis, and previous diagrams to describe what happens in...
Curated OER
Investigation of Meiosis in Common Plants and Animals
Students witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.
Curated OER
Plant Propagation
Middle schoolers successfully start a new plant by any means of vegetative propagation. They select a propagation method which is appropriate for the plant and keep a laboratory journal of the treatment and progress of the new plant.
Curated OER
Mitosis
Students explore the four stages of mitosis. They view a prepared slide of an onion root tip undergoing mitosis to identify the stage for each cell in view. They record the number of cells in each stage, graph the results, then calcualte...
