Lesson Plan: The Nucleus Biology • First Year of Secondary School

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.
