Electromagnetic Energy
This is the term for the sun’s energy.
Radiation
This is the more common term for electromagnetic energy
Photons
Electromagnetic energy travels in waves, but it also behaves like individual particles, photons.
Electromagnetic Spectrum
This is the full range of electromagnetic radiation in the universe - it includes visible light and radio waves.
Pigments
These are molecules that absorb some visible light rays and reflect others.
Absorption Spectrum
This is the range of photons that a molecule is able to absorb.
Carotenoids
Plant pigment that absorbs photons of green, blue and violet. It reflects the red, orange and yellow.
Chlorophyll
Plant pigment that absorb blue, violet and red photons and reflects green and yellow.
Autotrophs
This is an organism that can produce it’s own food by photosynthesis.
Chemosynthetic Autotrophs
These use energy from inorganic molecules to make their own food.
Photosynthetic Autotrophs
These use sun and light energy to make their own food.
Heterotrophs
These are organisms that can not produce their own food.
Cellular Respiration
This is when organisms unlock the energy in food, which originally came from the sun.
Aerobolic Respiration
Resperation that is oxygen dependent.
Photosynthesis
This is when light energy is transformed into stored chemical energy. Light Dependent
Reactions
These are reactions that produce ATP and NADPH and take place in the presence of sun-light.
NADPH
This is an electron carrier; it helps carry hydrogen atoms from one molecules to another.
Light Independent Reaction
This is the reaction that uses the ATP and NADPH to form the glucose from carbon dioxide.
Chloroplasts
This is a cell organelle in which photosynthesis takes place.
Thylakoids
These are the flattened sacs within the chloroplasts.
Grana
These are the stacks of thylakoids.
Stroma
This is the fluid that surrounds that thylakoids; it contains the enzymes of the light independent reaction.
Photocenters
These are the networks that are located in the thylakoids.
Chlorophyll a
The photo centers capture and send photon energy towards these pigments.
Photosystem II
During non-cyclic electron flow, energized electrons eject from here.
Electron Transport Train
This is where the electrons go after the photosystem II ejects them; it then triggers the production of ATP.
Photosystem I
Energized electrons eject from here along with hydrogen ions, reduce NADP+ to NADPH
Chemiosmosis
This is when a cell uses potential energy in a concentration gradient in order to ATP.
Carbon Fixation/ Calvin Cycle
This is when photosynthetic organisms use the ATP and NADPH from the light-dependent reaction in order to build organic molecules from atmospheric carbon dioxide.
