1. Aim: What are the functions of cell organelles? Ribosomes are responsible for assembling the proteins of the cell.

2. Ribosomes can be attached to the Endoplasmic Reticulum –Called rough ER

3. Endoplasmic Reticulum The endoplasmic reticulum is an extensive network of membranes composed of both regions with ribosomes and regions without ribosomes.

4. Golgi Apparatus responsible for manufacturing, warehousing and shipping certain cellular products, particularly those from the endoplasmic reticulum (ER). endoplasmic reticulum A Golgi complex is composed of flat sacs that are stacked.

5. Lysosome Lysosomes are membranous sacs of enzymes. These enzymes are typically hydrolytic and can digest cellular macromolecules hydrolytic

6. Aim:What are the functions of cell organelles ? Mitochondria Powerhouse of the Cell

7. Glucose Glycolysis Cytoplasm Pyruvic acid Electrons carried in NADH Krebs Cycle Electrons carried in NADH and FADH 2 Electron Transport Chain Mitochondrion Cellular Respiration occurs in the Mitochondria Mitochondrion Section 9-1 Go to Section: C 6 H 12 O 6 + 6 O 2 ----------> 6 CO 2 + 6 H 2 O + energy

8. ATP the energy bar

9. Centrioles function in cell division Centrioles are cylindrical structures that are composed of groupings of microtubules arranged in a 9 + 3 pattern. microtubules

10. Plant cell differences Cell wall Large vacuoles chloroplasts The electron micrograph shows cells from a sunflower leaf

11. Chloroplasts in the plant cell A typical plant cell (e.g., in the palisade layer of a leaf) might contain as many as 50 chloroplasts.palisade layer of a leaf

12. The overall chemical reaction involved in photosynthesis is: 6CO 2 + 6H 2 O (+ light energy)  C 6 H 12 O 6 + 6O 2 Summary: What is the relationship between respiration and photosynthesis?
