- Chlorophyll a
- Has an absorption spectrum of violet-blue and red light
- C4 Plants
- Prefaces the Calvin Cycle with an alternate mode of Carbon fixation that forms a four-carbon chain its first product
- Photosynthesis
- The conversion of light energy to chemical energy.
- Calvin Cycle
- The synthesis of glucose from the products in the Light Reactions
- Cartenoids
- Hydrocarbons that are various shades of yellow and orange because they absorb violet and blue-green light.
- Autotrophs
- Organisms that make their own food: "self-feeders"
- Photophosphorylation
- The addition of a Phosphate group to ADP, making ATP
- Stomata
- Microscopic pores on the surface of a leaf.
- Photorespiration
- When Rubisco binds to oxygen instead of CO2 because a plant's stomata have closed, thus negating the Calvin Cycle and preventing Glucose from being formed
- Carbon Fixation
- The initial incorporation of carbon into organic compounds
- Chlorophyll
- The green pigment located within chloroplasts
- C3 Plants
- Plants that use the intial fixation of carbon by rubisco
- Stroma
- The dense fluid within the Chloroplast
- NADP (+)
- An electron acceptor
- CAM Plants
- Store the organic acids made at night in vacuoles and use them for photosynthesis during the day when stomata are closed
- Glyceraldehyde-3-phosphate
- A three carbon sugar that makes up Glucose
- Light Reactions
- The step pf photosynthesis that converts solar energy to chemical energy
- Thylakoids
- An elaborate system of interconnected membranous sacs segregating the stroma from another compartment.
- Chlorophyll b
- Has a yellow-green color
- Heterotrophs
- Organisms that need to eat for energy
- Mesophyll
- The tissue in the interior of the leaf
- Bundle-Sheath Cells
- Photosynthetic cells in C4 plants that are packed tightly around the veins
