Organelle review
| Question | Answer |
|---|---|
| What is the liquid substance withing a cell called,and what is used as the "roadways" through it? | Cytoplasm, and Cyto Skeleton |
| What are the two different types of Ribosomes, where are they found, and what do they produce? | Bound- found connected to E.R., and nuclear envelope, and make protiens to be used by other organelles, or outside cell Free- found in cytosol,make protiens needed for cytossol reactions |
| What is the difference between the smooth and rough Endoplasmic Reticulum? | Smooth E.R.- Involved in synthesis of hormones, carbs and detox. Rough E.R.- involved in synthesis of protiens/glycoprotiens, and membrane self growth. |
| What is the main process of the Golgi? | The Golgi recieves products from the E.R. and MODIFIES them for release from the cell, then pinches the products off in vesicles for transport. |
| Which organells is responsible for recycling cell parts? | Lysosomes. |
| Which organelle releases H2O2 as a biproduct? | Peroxisomes. |
| Which organelle found in both plant and animal cells is MUCH larger in plant cells, and why? | Vacuoles, because plants must store large amounts of water, within their cells. |
| Which two organelles convert usable energy, and for which types of cells? | Chloroplasts- photosynthesising cells Mitochondria-nonphotosynthesing cells |
| cycle that takes place within the mitochondria? | Krebs Cycle |
| What are the folds of th emitochondrial membrane called, and why do cells have them? | Cristae, folds make more surface area, for ATP synthesis |
| Chloroplasts turn sunlight energy into usable energy, what are the 3 parts of a chloraplast? | 1) thylakoids- flattened membrane sac inside chloroplast used to convert solar energy to stored chemical 2) granum- the stacked part of thylakoid, where light reactions occur 3) stroma- fluid in chloroplast where sugars are made from CO2 and H2O |
| what is the main function of microtubules? | cell movement(both inside and out, and mantainance of cell shape. |
| what cells are you most likely to find alot of microfilaments? | Muscle cells(for movement) |
| What 2 organelles do plants have that animal cells don't? | Cell wall, and chloroplasts. |
| what are plasmodesmata? | open channels in cell walls connecting the cytosols of different, adjacent cells |
