Term
Photosynthesis
Definition
plants use energy from sunlight to convert water and carbon dioxide into high energy carbohydrates, sugars, starches, oxygen and waste products
Term
Pigments
Definition
the plants light absorbing molecule that absorbs the suns light energy
Term
Thylakoids
Definition

[image]

a sacklike photosynthetic membrane. arranged in stacks called grana or singular: granum

Term
photosystems
Definition

[image]

proteins in the thylakoid membrane organize chlorophyll and other pigments into clusters

Term
stroma
Definition
region outside the thylakoid membrane, the Calvin - Benson Cycle takes place here
Term
light - dependent reactions
Definition

[image] 

other wise known as photophosphorylation. it requires light and produces oxygen gas and convert ADP and NADP+ into the energy carriers ATP and NADPH

Term
ATP synthase
Definition
spans the membrane and H+ ions to pass through it.
Term
Calvin Cycle
Definition

[image]

light-independent reactions. uses ATP and NADPH from the light-dependent reactions to produce high energy sugars

Term
chlorophyll
Definition
plants principal pigment. reflects green light.
Term
photosyntesis equations
Definition

[image]

photosynthesis uses the energy of sunlight to convert water and carbon dioxide into high energy sugars and oxygen
