Cell Biology Flashcards
Eukaryotes cell
Animal + Plant Cell
Prokaryotes cell
Bacteria Cell
Cell membrane
Controls which substances can pass in and out of the cell
Nucleus
Contains genetic material/DNA and controls the cells activities
Cytoplasm
Jelly like substance where chemical reactions take place
Mitochondria
Site of aerobic respiration so they release energy for the cell.
Ribosomes
Where proteins are made
Cell wall
Made of cellulose. This makes it strong and allows it to maintain the shape of the cell.
Vacuole
A large sac in the middle of the cell that contains a watery solution of sugars and salts (cell sap). It helps maintain the structure and shape of the cell.
Chloroplasts
Photosynthesis takes place with energy from the sun. Contains a green pigment chlorophyll absorbs light energy to help with photosynthesis
Object
The real sample you are looking at
Image
What you see when you look down a microscope
Magnification
How many times larger the image is than the object
Resolution
The measure on how detailed an image is.
Name 3 advantages of a light microscope

- Rely on Light
Name 3 advantages of an electron microscope
- Uses electrons
- 2000x better than a light microscope
- Higher resolution
What are 3 reasons new cells are required?
- Growth
- Development
- Repair
Mitosis
Makes identical copies to help you grow
Cytokinesis
Splitting of cell membrane
