Structures & Functions

3. Cells Are prokaryotic or eukaryotic
Prokaryotic cells have no nucleus (blue green algae, bacteria)
Eukaryotic cells have a true nucleus and organelles surrounded by membranes

4. Cytoplasm
Cytoplasm is the substance that fills the inside of a cell, and contains cell structures.

5. Cytoplasm
Cytoplasm is sort of like jello inside of the cell membrane.

6. The Nucleus Found in eukaryotic cells The control center of the cell
Contains chromosomes, the genetic blueprints of the cell (DNA or chromatin)
Separated from the rest of the cell by a membrane called the nuclear envelope

7. The Nucleus
Contains a cellular material called nucleoplasm (sort of like cytoplasm)

8. Cell Membrane
The membrane of a cell allows some things to go through it, and keeps others out

9. Golgi Apparatus
The Golgi apparatus is a series of smooth, stacked membranous sacs.

10. Golgi Apparatus
It is the packaging and shipping center of the cell.

11. Endoplasmic Reticulum
The E.R. transfers materials throughout the inside of the cell

12. Mitochondria
Mitochondria are tiny sausage-shaped structures found in the cytoplasm of the cell, and are responsible for energy production

13. Vacuoles
Vacuoles are used for storage of waste, food, or water

14. Lysosomes
Digestion and break down of waste, worn out cell parts, and foreign substances

15. Ribosomes
Makes proteins needed by the cell

16. Centrioles
Involved in helping a cell to copy itself

17. Chloroplasts Chloroplasts are where photosynthesis takes place.
Found only in plant cells.

18. Chloroplasts
Traps sunlight energy
Makes sugar (food) for the plant.

19. Cell Wall Stiff, rigid, nonliving.
Provides support so that the plant can grow tall and protection.
Found only in plant cells.
