QuestionAnswer
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
