Lesson Plan: The Nucleus Biology
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the structure of the nucleus in a eukaryotic cell and recall the structure and function of chromatin and chromosomes.
Objectives
Students will be able to
- recall that the nucleus is a spherical organelle that contains the genetic material of the cell,
- describe the structure of the nucleus, including the double membrane (nuclear envelope), the nuclear pores, the nucleoplasm, and the nucleolus,
- state that the nucleoplasm contains chromatin,
- describe the structure of a chromatid as a strand of DNA coiled around proteins (histones),
- describe how the structure of chromatin changes into chromosomes as the cell prepares to divide,
- recall that chromosomes contain the genetic material that controls the cell’s activities and is passed from parents to offspring.
Prerequisites
Students should already be familiar with
- a basic outline of the structure of a eukaryotic cell.
Exclusions
Students will not cover
- details of the stages of mitosis,
- details of inheritance.
