- Organelles in a cell
- Nucleus
- Contains nearly all genetic material
- Has instructions for making protiens
- Makes RNA & ribosomes
- Endoplasmic reticulum (ER)
- Smooth
- Role?
- Involved in making the lipids that the cell needs.
- Role?
- Rough
- Role?
- Transports proteins that were made on the attached ribosomes
- Rough because it is "studded" with ribosomes
- Role?
- Smooth
- Golgi apparatus
- Role?
- Receives proteins from the ER and modifies them
- May add sugar molecules to them.
- After the proteins have been modified.
- The Golgi Apparatus packages the modified proteins into vesicles that can be transported
- Receives proteins from the ER and modifies them
- Role?
- Mitochondria
- Role?
- Produce most of the ATP during respiration.
- ATP
- DEF: A molecule that when broken down, releases energy that the cell uses for other reactions
- Role?
- Chloroplasts
- Only found in plant cells
- They are the site of photosynthesis in plant cells
- Light energy is used to drive the reactions of photosynthesis, in which carbohydrate molecules are made from carbon dioxide and water
- Lysosomes
- Contain powerful digestive enzymes.
- Their role is to break down materials, for example white blood cell lysosomes help break down invading micro-organisms
- Contain powerful digestive enzymes.
- Organelles without membranes surrounding them
- Ribosomes
- Role?
- The site of protein synthesis in the cell.
- Protein synthesis: Where new proteins are made
- They act as an assembly line where coded information (mRNA) from the nucleus is used to assemble proteins from amino acids
- The site of protein synthesis in the cell.
- Role?
- Centrioles
- Role?
- Take part in cell division. They form fibres, known as spindle, which move chromosomes during nuclear division
- Role?
- Ribosomes
- Nucleus
- After the proteins have been modified.
- The Golgi Apparatus packages the modified proteins into vesicles that can be transported
- DEF: Vesicle is a membrane bound sac found in cells and used to transport materials around the cell
