Cellular Organelles Review Sheet 1. Introduction: a. Role of nucleus: (2) Gene control, control center for information b. ER : i. Rough has: it has ribosomes, ii. Ribosomes function: produce proteins iii. Smooth ER responsible for (2) lipids and break down of toxins c. Golgi complex: to other parts of the cell or outside the cell. It also produces lysosomes. d. Lysosomes break: materials when those materials not used. e. Vacuole is important in storage. f. Energy organelles: i. Mitochondria for making ATP. ii. Chloroplasts make: sugar for the mitochondria. 2. Ribosomes: a. What are ribosomes made up of? (2) prteins and rRNA b. Where is it synthesized? nucleulos c. How many subunits make up a ribosome? 2 d. Why does mRNA go through the middle? Tells the protein what to produce, message. 3. Endoplasmic Reticulum: a. What is the ER usually attached to? Outside of the nucleus b. Rough ER has ribosomes on it so it can synthesize proteins c. Smooth ER is where lipids are synthesized. (Mentioned above) d. The function of the ER is to be a lattice so cells can build things. 4. Golgi Complex: a. Tell about some of the accomplishments of Camillo Golgi he was really good at staining ells to figure out how organelles work. b. Purpose: takes information that is made in the ER and takes the information that is made in the ER and ships them out around the cell. 5. Lysosome: a. Purposes: (3 discussed) i. Digest material ii. Dissolve un-functioning mitochondria Kill cells. iii. b. Why is it referred to as the “suicide sack”? enzymes located in the lysosome can kill the cell that it is located. 6. Mitochondria: a. Purpose: Energy production ATP. b. Why is their folding on the cristae and why is that significant? To increase surface agrea, this allows mitochondria to make more ATP. 7. Vacuole Purposes: i. ii. iii. iv. v. Storage Store materials Pigments Chemicals Cell growth 8. Chloroplast: a. Purpose: i. ii. Photosynthesis Create sugars b. The reason there is increased surface area is for: (2) absorb more light and increase chemical reactions.
