1. Chapter 7 Cell Structure

2. Microscopes Are used to discover cells

3. Cells All living things are made up of cells Cells come from preexisting cells Cells are the basic units of structure and function in organisms

4. Cells Smaller cells can move materials in and out of them quicker because the surface are is smaller.

5. Proteins Are made on ribosomes on rough endoplasmic reticulum

6. Plants Plants have two organelles that animal cells don’t have – Chloroplasts – Cell Wall

7. Prokaryotes Bacterium have genetic material formed in a single loop of DNA Do not have their DNA enclosed in a Nucleus ** No nucleus

8. Eukaryotes Cells with a true nucleus The nucleus is contained in a membrane called the nuclear envelope or the nuclear membrane

9. Organelles Inside a cell and located between the nucleus and the cell membrane is a substance called the cytoplasm

10. Cytoskeleton The web of protein fibers that help organize the part of a eukaryotic cell are called the cytoskeleton.

11. DNA Deoxyribonucleic acid Carries the instructions for making proteins Found in the nucleus

12. Lysosomes Enzymes that can digest food are found in vesicles called lysosomes. Known as the “garbage disposal” of the cell.

13. Endoplasmic Reticulum and Ribosomes

14. Flagella A structure that sticks out from the cell’s surface and allows it to move A whip-like structures that is used for movement

15. Cell Membrane Controls what enters and leaves a cell

16. Tissues Groups of cells that have similar structures and functions

17. Organs Heart Lungs Kidney Brain Are examples of organs

18. Colonial Organisms An organism made of many cells that are permenantly together and coordinate their activities

19. Multicellular Organisms Cells are arranged into tissues, organs and organ systems
