1. Cell Parts and Functions

2. Cell Wall
Only in plant cells
Helps to support and protect the cell

3. Cell Membrane All cells have a cell membrane
Controls which substances go into and out of a cell which include food, water and oxygen

4. Nucleus
The control center of a cell directing all of the cells activities
Also houses the DNA or genetic material of the cell

5. Nuclear Envelope The membrane the surrounds the nucleus
Allows material to pass into or out of the nucleus while keeping bad stuff out

6. Chromatin
Tiny thread like material in the nucleus that contain the genetic material and direct the cells functions.

7. Nucleolus
A dense ball inside the nucleus where ribosomes are made

8. Cytoplasm
Region between the cell membrane and the nucleus that is a thick gel like substance
Contains most of the cells organelles
The liquid part of the cell

9. Mitochondria
Known as the powerhouse of the cell because they convert energy in food molecules into energy the cell can use and carry out it’s functions.

10. Endoplasmic Reticulum (ER)
Passageways that carry proteins and other molecules from one part of a cell to another

11. Ribosomes
Attach to the surface of the ER and function as factories to produce proteins

12. Golgi Bodies
Receive proteins and other newly formed materials from the ER, package them, and distribute them to other parts of the cell

13. Chrloroplasts ONLY in plant cells
Capture energy from sunlight and use it to produce food for the cells
Contain chlorophyll which is a green pigment that gives plants their green color

14. Vacuoles Storage area of the cell Most plants have one large vacuole
Some animal cells do not have vacuoles.
Can store food and waste products

15. Lysosomes
Small round structures that contain chemicals that break down certain materials in a cell
To lyse means to split

16. Know this!!! There are levels of organization involving cells
In many-celled organisms cells are often organized into
Tissues
Organs
Organ systems
