  1. Cell Structure: Nucleus, Nuclear Envelope, and the Nucleolus By: Esteban Garcia

  2. THE Nucleus

  3. Function: the nucleus Regulation of Cell Activity: the nucleus can be described as the “brain” of a cell • The nucleus is the control center of cells, it is like our brain because it makes sure any processes that must happen in the cell happen (reproduction, movement, eating, etc.) , the same way our brain tell our body what to do in order for us to survive.

  4. function: The nucleus DNA STORAGE: Another important function of the nucleus is that it stores hereditary information. • - The nucleus stores most of the genetic information of a cell. • - The cell nucleus also contains the cell’s DNA.

  5. Structure: Cell nucleus The cell nucleus is composed of many different parts. • The main parts of a cell’s nucleus are the nuclear envelope and the nucleolus, but it also has pores, nucleoplasm, and chromosomes.

  7. The nuclear envelope

  8. Function: The nuclear envelope The nuclear envelope is the part of the nucleus that surrounds the nucleus, hence the name “nuclear envelope” • The main function of the nuclear envelope is to keep the nucleus separated from the rest of the cell • Another important function is that it allows materials to flow in and out of it’s pores and therefore out of the nucleus

  9. Structure: The nuclear envelope The nuclear envelope is made up of a phospholipid bilayer • The nuclear envelope is made up of a phospholipid bilayer • The nuclear envelope also has pores which allow the nucleus to communicate with the other organelles within a cell, by allowing certain molecules in and out of the nucleus.

  11. The Nucleolus

  12. Function: nucleolus The nucleolus is part of the cell’s nucleus, and it is basically the “brain” of a nucleus. • The main function of the nucleolus is to put together the subunits of ribosomes.

  13. Structure: The Nucleolus The nucleolus is made up of three main components • The three main components of the nucleolus are: • fibrillar centers (FC) • dense fibrillar centers (DFC) • granular components (GC)
