|
Nucleus of Cell |
Contains DNA and controls the functions of the cell - All cells have it |
|
|
Cytoplasm |
Jelly-like substance in which most chemical reactions happen - all cells have it |
|
|
Mitochondria |
small structures in which aerobic respiration occurs. |
|
|
Cell membrane |
Thin skin around the cell, holds the cell together and controls what goes in and out - all cells have it |
|
|
Cell wall |
strong outer layer made of cellulose, provides support for cell - only Plant cells |
|
|
Vacuole |
Space filled with cell sap - a solution of sugars and salts. |
|
|
Chloroplasts |
These contain chlorophyll which absorbs sun energy which is used for respiration. - only plants have it |
|
|
Tissue |
Multiple similar cells grouped together |
|
|
Organ |
Multiple different tissues grouped together |
|
|
Sperm cells |
Sperm cells carry the male dna to the ovum it has a long tail to help it swim to the ovum It has lots of mitochondria to provide energy for this It carries enzymes to help it break through the ovum membrane |
|
|
Ovum |
Ovum carries the female dna in its nucleus contains food storage to feed the embryo in its early stages |
|
|
Root Hair Cells |
Cells used to absorb water and minerals from the soil for the plant. They have lots of tiny hairs to increase surface area and thin walls so it's easy for the water to go into the cell |
|
|
Aerobic Respiration |
Occurs in mitochondria Glucose + Oxygen = Water + Carbon Dioxide C6H12O6 + 6O2= H20 + CO2 Releases energy for cells to function Glucose comes from food and is carried to our cells from our bloodstream |
|
|
Carbon Dioxide Test |
Breath into limewater with a straw, it should turn milky. |
