1. 7-2 Cell Structures

2. CELL WALL Found in plants, fungi, most prokaryotes, and algae
Very outermost part of the cell
Provides support and protection
4. Made up of cellulose (starch/carbohydrate)

3. Nucleus
Controls most cell processes and contains the hereditary info of DNA
Holds the coded instructions for making proteins
Chromatin and Chromosomes
Chromatin – granular material visible within the nucleus
Consists of DNA bound to protein
Chromosomes – what chromatin condenses into when a cell divides

4. Nucleus nucleolus protein DNA chromosome Nuclear envelope
Assembly of proteins begin here
protein
DNA
chromosome
Nuclear envelope
Allow material in and out of nucleus (RNA)

5. Cytoskeleton
Network of proteins that helps to maintain its shape (microtubules and microfilaments)
Microtubules – maintain cell shape and can serve as tracks which organelles move on
Microfilaments – movement and support of cell

6. Organelles in Cytoplasm
Endoplasmic reticulum – organelle in which components are assembled and some proteins modified
Ribosomes – proteins are assembled here

7. Organelles in the Cytoplasm
Golgi apparatus or Golgi body
Stack of membranes in which enzymes attach carbohydrates and lipids to proteins. Golgi packages final product and sends it to its final destination.
Customization shop where finishing touches are put on the product.

8. Organelles in the Cytoplasm
Lysosome
Filled with enzymes used to break down food into particles that can be used
Also help to break down old cell parts
Custodial staff

9. Organelles in the Cytoplasm
Vacuole
Saclike structure that stores material.
most notably it stores water in plants
warehouse

10. Organelles in Cytoplasm
Chloroplast
Uses energy from the sunlight to make energy rich food. Photosynthesis.
Makes energy that the cell can use.
Solar power plants

11. Organelles in the Cytoplasm
Mitochondrion
Converts energy (from food produced by chloroplast) to energy the cell can use.
Fire place (releasing energy from wood)
