- Organelles- structure & function
- Nucleus
- Fuction
- The nucleus houses nearly all the cell's genetic material.
- The chromatin consists of DNA and proteins.
- It has instructions for making proteins.
- some of these proteins regulate the cells activities.
- when cells divide, chromatin condenses into visible chromosomes
- It has instructions for making proteins.
- Fuction
- Endoplasmic reticulum (ER)
- Function
- Golgi apparatus
- Function
- Mitochondria
- Function
- is where ATP is produced (adenosine triphosphate) during respiration
- ATP is sometimes called the universal energy carrier
- as almost all activities in the cell are driven by the energy release from ATP
- Function
- Chloroplasts
- Function
- site of photosynthesis in plant cells
- light energy is used to drive reactions of photosynthesis, in which carbohydrate molecules are made my co2 and water
- Function
- Lysosomes
- Function
- contain powerful digestive enzymes
- rold to break down materials, eg white blood cell lysosomes break down invading microorganisms
- specialised one is the head of a sperm cell
- penetrates the egg by breaking down the material surrounding it
- Function
- Nucleus
