Cell Organelles

1. Cell Organelles

2. Cell Organelles • Organelle= “little organ” • Found only inside eukaryotic cells

3. Nucleus • Found ONLY Eukaryotes • Found in BOTH plant and Animal cells in the cytoplasm • Control center of the cell that contains DNA

4. Cell Membrane • Found in BOTH PROKARYOTES and EUKARYOTES • Found in BOTH plant and animal cells • Located outside the cytoplasm • Controls the passage of materials into and out of the cell.

5. Cytoplasm • Found in BOTH PROKARYOTES and EUKARYOTES • Found in BOTH plant and animal cells • Location outside the nucleus or in between cell membrane • Jelly-like material where All organelles reside (live and float around in)

6. Ribosome • Found in BOTH PROKARYOTES and EUKARYOTES • Found in BOTH plant and animal cells • Found attached to rough ER or floating free in cytoplasm • Site of protein synthesis (produces proteins)

7. Endoplasmic Reticulum • Found in EUKARYOTES ONLY • Found in BOTH plant and animal cells • Located in the cytoplasm • Responsible for producing lipids and TRANSPORTING proteins.

8. Golgi Apparatus • Found in EUKARYOTES ONLY • Found in BOTH plant and animal cells • Located in the cytoplasm • Stores, modifies and packages proteins

9. Lysosomes • Found in EUKARYOTES ONLY • Found in ANIMAL cells ONLY • Located in the cytoplasm • Garbage disposal of the cell that contains enzymes that break down wastes

10. Mitochondria • Found in EUKARYOTES ONLY • Found in BOTH plant and animal cells • Located in the cytoplasm • “Powerhouse of the cell” that does Cellular respiration to produce ENERGY for the cell

11. Chloroplast • Found in EUKARYOTES ONLY • Found in PLANT cells only • Located in the cytoplasm • Site of glucose production called PHOTOSYNTHESIS.

12. Cell Wall • Found in PROKARYOTES and EUKARYOTES • Found in PLANT cells ONLY • Located outside of the cell membrane • Rigid structure made of cellulose that provides PROTECTION and SUPPORT.

13. Plasmid • Found in Prokaryotes ONLY • NOT found in PLANT or ANIMAL cells • Located in the cytoplasm of bacteria cells • Circular pieces of Deoxyribonucleic acid (DNA) that contains genetic information.

14. Chromosome Found in BOTH PROKARYOTES and EUKARYOTES FOUND IN BOTH PLANT AND ANIMAL CELLS. IN PROKARYOTES – FOUND IN CYTOPLASM IN EUKARYOTES – FOUND IN THE NUCLEUS Thread like structures that contains DNA

15. Vacuoles • Found in Eukaryotes ONLY • Found in both PLANT and ANIMAL cells. • Found in cytoplasm Large in PLANT CELLS but very small in animal cells. • Storage container for water, food, enzymes, wastes, pigments, etc.

16. Prokaryote vs Eukaryote EUKARYOTES Evolved from prokaryotes Have a nucleus Hereditary info is contained within the nucleus Ex: Animals, Protists, Fungi, Plants PROKARYOTES • First cells to evolve • No nucleus • Eukaryotes • Hereditary info is contained within cytoplasm • Ex: Archaeabacteria, Eubacteria

17. Quick Review • Which organelle is the control center of the cell? Nucleus • Which organelle controls the passage of materials into and out of the cell? Cell membrane • Which organelles are not found in animal cells? Cell wall, LARGE central vacuole, chloroplasts • Which organelle helps plant cells make food? Chloroplasts • What does E.R. stand for? Endoplasmic reticulum
