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

Ribosomes can be attached to the Endoplasmic Reticulum Called rough ER

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

Golgi Apparatus responsible for manufacturing, warehousing and shipping certain cellular products, particularly those from the endoplasmic reticulum (ER). A Golgi complex is composed of flat sacs that are stacked. Cells that specialize in secreting various substances typically have a high number of Golgi complexes. http://biology.about.com/library/weekly/aa042000a.htm

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

Aim:What are the functions of cell organelles ? Mitochondria are the cells' power sources. They are distinct organelles with two membranes. Usually they are rod-shaped, however they can be round. The outer membrane limits the organelle. Mitochondria Powerhouse of the Cell

Cellular Respiration occurs in the Mitochondria Section 9-1 Mitochondrion Electrons carried in NADH Electrons carried in NADH and FADH2 Pyruvic acid Glucose Electron Transport Chain Krebs Cycle Glycolysis Sugar is broken down in the membranes of the mitochondrion to produce 36 molecules of ATP = adenosine triphosphate Mitochondrion Cytoplasm C6H12O6 + 6 O2 ----------> 6 CO2 + 6 H2O + energy Go to Section:

ATP the energy bar This is what is produced in the mitochondria, ATP. Energy is stored in the covalent bonds between phosphates, with the greatest amount of energy (approximately 7 kcal/mole) in the bond between the second and third phosphate groups. This is what is being made in the mitochondria.

Centrioles function in cell division Centrioles are cylindrical structures that are composed of groupings of microtubules arranged in a 9 + 3 pattern. The pattern is so named because a ring of nine microtubule "triplets" are arranged at right angles to one another. Centrioles are found in animal cells and play a role in cell division.

Plant cell differences Cell wall Large vacuoles chloroplasts Chloroplasts are the most familiar plastids. They are usually disk-shaped and about 5-8 µm in diameter and 2-4 µm thick. A typical plant cell has 20-40 of them. The electron micrograph shows cells from a sunflower leaf

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. The thylakoid membranes enclose a lumen: a system of vesicles (that may all be interconnected). At various places within the chloroplast these are stacked in arrays called grana (resembling a stack of coins). The fluid stroma contains: all the enzymes needed to carry out the "dark" reactions of photosynthesis; that is, the conversion of CO2 into organic molecules like glucose.

The overall chemical reaction involved in photosynthesis is: 6CO2 + 6H2O (+ light energy)  C6H12O6 + 6O2

Research looks at how environment inside a living cell affects protein structure

Summary: What is the relationship between respiration and photosynthesis? Which cells, animal or plant, undergo both respiration and photosynthesis?
