|
Nucleus |
Contains genetic material that controls the activities of the cell |
|
|
Cytoplasm |
Chemical reactions take place |
|
|
Cell membrane |
Holds the cell together and controls what goes in and out |
|
|
Permanent vacuole |
Contains cell sap, a weak solution of sugar and salts |
|
|
Chloroplast |
Where photosynthesis occurs. Contains chlorophyll |
|
|
Chlorophyll |
A green substance which absorbs the light needed for photosynthesis |
|
|
Eukaryotic cells |
Are complex (animal and plant cell) |
|
|
Prokaryotic |
Small and simple cells, like bacteria |
|
|
Cell wall |
Made out of cellulose. It supports the cell and strengthens it |
|
|
Light mocroscope |
Use light ans lenses to form and image of a specimen and magnify it. |
|
|
Electron microscope |
Uses electrons instead of light to form an image and have a much higher magnification and resolution. |
|
|
Magnification |
Image size / real size |
|
|
Sperm cells |
Reproduction, get the male DNA to the Female DNA. It has a long tail and a lot of mitochondria in the cell to provide energy to swim. It also has enzymes in the head to digest the egg membrane |
|
|
Nerve cell |
Rapid signaling. These cells are long and have a branched connections to connect with other nerve cells |
|
|
Muscle cells |
Contraction. These cells are long and contain lots of motochondria |
|
|
Root hair cells |
Big surface area to absorb water and mineral ions through diffusion |
|
|
Stem cells |
Can replace any kind of faulty cells, as they are undifferentiated. |
|
|
Alveoli |
1.Large surface area 2.moist lonig for dissolving gases 3.thin walls 4.good blood supply |
|
|
Villi |
Found in the small intestine. They have a large surface area to absorb food in the blood quicker. Have 1 cell thick wall and a good blood supply |
|
|
Stomata |
It is an exchanging surface where CO2 and O2 diffuse. |
|
|
Guard cells |
Close the stomata if the water lost is higher than the absorbed water in the roots. |
|
|
Air spaces in the leaf |
Increase the surface area so the CO2 can diffuse easier into the cells |
|
|
Starch is broken down by |
Amylase into sugars |
|
|
Proteins are broken down by |
Protease into amino acids |
|
|
Lipids are broken down by |
Lipase into fatty acids and glycerol |
