1. Cell Structure & Function
Cells and Heredity
Chapter 1.2 (pgs )

2. Inside the Cell
Humans are made up of several bodily systems (Respiratory, Nervous, Digestive) that utilize organs
Cells have similar structures, called organelles.

3. Entering a Cell
Animal cells have only a Cell Membrane, which allows materials in & out of the cell.

4. Entering a Cell Cells are held together with a Cell Wall
Found only in plant cells
Rigid layer made of cellulose

5. The Nucleus The “brain” of the cell Has a Nuclear Membrane
Controls all aspects of the cell’s activity
Has a Nuclear Membrane
Protects the Nucleus just like the Cell Membrane.

6. Into the Cytoplasm
The area inside the cell is called the Cytoplasm, which is constantly churning
Contains many organelles.

7. Cell Wall Cell Membrane Nuclear Membrane
The structure that allows materials In & Out of an animal cell is called… 1
Cell Wall 2
Cell Membrane 3
Nuclear Membrane

8. Mitochondria produce the energy a cell needs
Oodles of Organelles
Mitochondria produce the energy a cell needs
Vacuoles are storage areas in the cell
Lysosomes break down food and parts

9. The ER
The Endoplasmic Reticulum is the passageway that materials travel along
Ribosomes on the ER are protein factories, to build & repair cells
Golgi Bodies package and ship materials to other parts of the cell.
