- cells
- nuclues
- contains genetic material, which controls the activities of the cell
- cytoplasm
- most chemical reaction happen here
- cell membrane
- controls the movement of substances into and out of the cell
- mitrochondria
- most energy is released by respiration here
- ribosomes
- protein synthesis happens here
- cell wall
- strengthens the cell
- chloroplasts
- contains chlorophyll
- permanent vacuole
- filled with cell sap to help the cell
- chromosomes
- the human body has 46 chromosome 23 pairs
- mitosis
- when new cells have to be produced they must identical to the parent cell. when the parent cell divides into 2 daughter cells it is called mitosis
- Cancer
- benign- slow growing easy to remove not cancerous and rarely spread
- malignant- grows faster can spread easily can spread rapidly
- prokaryotic cells
- small cells their DNA is not enclosed in a nucleus
- Stem cells
- they are found in the developing embryo
- transplanting stem cells could help people with spinal injuries cancer and alzheimer's
- therapeutic cloning
- the idea is to produce stem cells with the same genes as the patient then have a nuclear transfer. the nucleus from the patient is then transferred to an egg cell that has had it's nucleus removed
- aerobic respiration
- is respiration using oxygen. it takes place in animal and plant cells
- respiration
- is the continuously occurring process used by all organisms s to release the energy they need from their food
- anaerobic respiration
- is respiration without oxygen this occurs in yeast and cytoplasm of cells
- nuclues
