UCLEUS
- 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.

- The nucleus stores most of the genetic information of a cell.
- The cell nucleus also contains the cell’s DNA.DNA STO

STRUCTU
RE: CELL
NUCLEUS - The main parts of a
cell’s nucleus are the nuclear envelope and the nucleolus, but it also has pores, nucleoplasm, and chromosomes.
The c
ell nucle
us is c
omposed
of man
y
different p
arts.

ENVELO
PE- 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

STRUCTU
RE: THE N
UCLEAR
ENVELO
PE- 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.

STRUCTU
RE: THE
NUCLEOLUS The three main
components of the nucleolus are:
- fibrillar centers (FC)- dense fibrillar centers
(DFC)- granular components
