Question | Answer |
---|---|
an organism that can make it's own food/energy Ex: Plants | Autotroph |
an organism depends on other organisms to supply it's food/energy Ex: human | heterotroph |
the process of a plant capturing the energy of the sun by chlorophyll absorbing the energy in the chloroplast | Stage 1 Photosynthesis |
The cell uses the energy and oxygen to produce sugar and oxygen | Stage 2 Photosynthesis |
a green pigment in the chloroplasts | Chlorophyll |
Opening in the underside of a leaf, lets out and brings in carbon dioxide | Stomata |
sugar + oxygen | Carbon dioxide + water |
cells break down sugar and release the energy | Respiration |
In the cytoplasm molecules of glucose (sugar) are broken down into smaller molecules | Stage 1 Respiration |
In the mitochondria the smaller molecules use oxygen to further break down the molecules which release energy | Stage 2 Respiration |
When the body can't supply the cell oxygen anymore, this supplies the cells with energy without using oxygen | Fermentation |
Occurs in yeast | Alchoholic Fermentation |
occurs in muscles | Lactic acid fermentation |
