Term
autotrophs
Definition
organisms that obtain energy from non-living things (plants from sun)
Term
plants are known as ______autotrophs
Definition
photoautotrophs
Term
Why are plants green?
Definition
Because green is the one color of the visible light spectrum that plants do not absorb, so it bounces off of the plants
Term
LIGHT WAVES
Definition
long to shortgamma, x-ray, ultraviolet, visible light (ROGYBIV in reverse), infared, radio
Term
What determines the energy of light
Definition
the shorter the wave length, the more energy
Term
Structure of the Chloroplast
Definition
there is an outer membrane and in the inner part of the chloroplast, there are organized sacks of thylakoids, which contain cholraphyll, which converts all visible light into energy except for green. Also in the chloroplast, outside the thylakoids, there is the stroma, which is where the Calvin Cylce occurs
Term
equation of photosynthesis
Definition
6CO2+6H2O (with light energy and chorophyll) becomes c6h12o6 +3o2
Term
Calvin Cycle
Definition
look in notebook
Term
turning light into energy
Definition
notebook
Term
Rate of Photosythesis
