- organsims that use photosynthesis to to convert light energy into chemical energy
- Autotrophs
- a process used by plants to convert the sun's light energy into chemical energy
- Photosynthesis
- Organisms that get energy from food instead of from sunlight
- Heterotrophs
- a series of reactions that take sunlight and convert it into NADPH and ATP
- Light Reactions
- organelle found in plants that contains the pigment chorophyll and is where photosynthesis takes place
- Chloroplast
- the inner membrane of the chloroplast that is arranged in sacs "pancakes"
- thylakoids
- stacks of thylakoids
- grana
- the solution or liquid part of the chloroplast
- stroma
- compounds that absorb certain colors of light
- pigments
- the main pigment involved in photosynthesis occuring in two types, A and B
- Chlorophyll
- accessory pigments found in plants...the browns, yellows, and oranges
- carotenoids
- cluster of pigment molecules "chlorophyll" and the proteins they are embedded in
- photosystems
- the protein that accepts the electrons lost from chlorophyll A
- primary electron acceptor
- a series of proteins found in the thylakoid membrane that electrons travel down losing energy as they do so
- electron transport chain
- the process of making ATP by Hydrogen ions diffusing through the Protein ATP Synthase
- chemiosmosis
- a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
- Calvin cycle
- creation of organic compounds using Carbon dioxide as in photosynthesis
- carbon fixation
- pores or openings found on the underside of leaves where plants can take in carbon dioxide but, lose water while doing so
- stomata
- plants that struggle with getting enough carbon dioxide can fix it into a 4 carbon compound instead of the usual six
- C4 pathway
- pathway used by plants that take in carbon dioxide at night and use it during the day to avoid losing as much water
- CAM pathway
