- 1What is an organelle?Smaller part of the cell which has a specific function.
- 2What is cytoplasm?Contents of the cell inside the cell membrane and outside the nuclues containing the organelles
- 3What is cytoskeleton?Dense network of protein fibers running throughout the cytoplasm that gives the cell shape and a basis for movement
- 4What is cytosol?Complex mixture of cytoskelton filaments, dissolved molecules and water that fills most of the volume of the cell
- 5What is the centriole made of?9 sets of triplet microtubules
(Barrel shapped organelles)
- 6How to flagella move a cell?Extend the rear of the cell and push it forward with snakelike wriggling
- 7How do cilia move materials?They are tread like projections that beat in a regular fashion to sweep material along
- 8What are microfilaments?Two intertwined strands of actin protein
- 9What is the function of microfilaments?Cell movement
Cell Shape
Cell Division
Holding the cell toegther
- 10What are intermediate filament?Fiberous proteins coiled into chick cabels
- 11What is the function of intermediate filaments?Cell shape
Anchoring nuclues to organelles - 12Function of RibsomesHelp in the sythesis of proteins, either for the cell to use or for the cell to transport
- 13How many sub-units are there of the ribosome?2
Large subunit
Small subunit - 14Where are ribosomes found?Some can be found in the cytoplasm but most are found on the endoplasmic reticulum
- 15Describe the golgi apparatusCurved saccules (Stack of pancakes)
- 16What is the function of the golgi apparatus?Recieve proteins and lipid filled vesicles from ER. Packages and processes them and distributes them within the cell or exports them out
- 17What is the seconadray function of the golgi apparatus?Encloses digestive enzymes into membranes to form lysosomes
- 18What are lysosomes?Circular structures that are bigger than ribosomes that are nicknamed the clean up crew
- 19What are the functions of lysosomes?Breakdown food into smaller particles that the cell can use (Powerful digestive enzymes)
+
Destroy invaders and old cells - 20What is perioxisome?A small organelle containing oxidase enzymes which detoxify toxins and free radicals
- 21Descrice the mitochondriaPowerhouse of the cell. They contain DNA and can replacate themselves and are bound by a double membrane.
- 22What is the function of the mitochondria?Energy formation
Breaks down food to release ATP - 23Describe the nucleus of the cellLargest organelle and known as the brain
- 24What is the function of the nucleus?seperates the DNA from the rest of the cell
- 25What is the nuclear envelope?Double membrane structure which seperates the nuclues from the cytoplasm
- 26What is the nuclear plasma?semifluid medium inside the nucleus
- 27What is the nucleolus?
