Analyzing the Stages of Mitosis Theme: Organization

Starter…pair discussion How would you identify each of the following stages? – Interphase – Telophase – Metaphase When looking at any tissue, what stage do you expect most of the cells to be in? How would the amount of stem cells in mitosis, compare to the amount of muscle cells in mitosis?

By the end of this lesson, students will be able to: Identify the stages of the cell cycle in plant cells. Explain how and why mitotic rates differ in cortex and meristem. Apply understanding of mitotic rate to a cancerous tissue.

Plant Tissues Vascular Dermal Ground Meristem

Applying the plant tissues to looking at a root tip! Vascular Bundle: – No nuclei! Cortex: – Metabolically active Meristem: – Growth of tip

Am I looking at the right spot? Color doesn’t mean anything; different slides are different colors. Cortex cells are larger Meristem cells are smaller

Introduction: Review interphase, mitosis, and cytokinesis and write a paragraph discussing the cell cycle.

Methods: Independent variable: What we are comparing! Dependent variable: What data will be collected! Controls: How to count in pairs!
