VISIBLE LIGHT SPECTRUM
_______________ is the MAIN CHLOROPHYLL MOLECULE
CHLOROPHYLL A
Name the source of energy that powers EACH STAGE of photosynthesis
SUNLIGHT
What STRUCTURE is used by plants to perform gas exchange?
The STOMA
The ORGANELLE for photosynthesis.
The CHLOROPLAST
The PHOTOSYNTHETIC CELLS of a plant are MOST LIKELY to be found in the __________ of a plant.
LEAVES
State the role of CO2, H2O, and solar energy in photosynthesis.
- CARBON DIOXIDE PROVIDES the carbon atoms for sugar molecules
- WATER acts as a source of ELECTRONS
- Solar energy powers the entire chemical reaction
The PLANT STRUCTURE that plants use to absorb water.
ROOTS
The equation that summarizes PHOTOSYNTHESIS
6CO2 + 6H2O ——-> C6H12o6 +6O2
What MOLECULE serves as the source for RELEASED OXYGEN?
H2O (WATER)
PHOTOSYNTHESIS vs. CELLULAR RESPIRATION
Photosynthesis CAPTURES light energy to make food
Cellular respiration BREAKS DOWN food to release energy
The name of the cellular process used by plants to make their own organic compounds.
PHOTOSYNTHESIS
The ultimate energy source for food production.
THE SUN
The molecule that absorbs light energy during photosynthesis.
CHLOROPHYLL
The organelle that houses the chromosomes.
The NUCLEUS
