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.


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.


Students should already be familiar with

  • a basic outline of the structure of a eukaryotic cell.


Students will not cover

  • details of the stages of mitosis,
  • details of inheritance.
