5. Chloroplast Structure:
3. Location -
Chloroplast Structure:
CHLOROPLAST
How do plants absorb light?
Notice the stacks inside of the chloroplast. These stacks absorb sunlight. This arrangement increases the amount of __________________________________ to absorb as much sunlight as possible.

6. Pigments PIGMENTS ABSORB REFLECT REFLECTS GREEN PHOTOSYNTHESIS
Plants contain _____________________ that _______________ some wavelengths of light and ________________ others.
ABSORB
REFLECT
For example, if a plant appears red, the plant ________________ this color. ______________________ is one of the most abundant pigments in a plant which absorbs the red and blue colors of the spectrum and reflects ________________ which is what makes plants appear green. The light plants absorb is used to undergo __________________________.

11. The equation for aerobic respiration is:
Occurs with ___________________
The equation for aerobic respiration is:
_________ + _________  ________ + _______ + ___ATP
OXYGEN
C6H12O O CO H
GLUCOSE OXYGEN CARBON WATER
DIOXIDE

12. Anaerobic Respiration
Occurs without
Two types of fermentation
1. ALCOHOLIC Fermentation occurs in _____________.
Equation: __________ ________ + _____ + ____ ATP
This process is used in baking bread and in brewing.
What causes bread dough to rise? _____________
(FERMENTATION)
OXYGEN
Yeast
C6H ETHANOL CO
CARBON DIOXIDE

13. Lactic Acid Fermentation - occurs in cells
Equation: ______________ __________________ + _____ ATP
This process occurs when exercising. If your muscles are depleted of oxygen they will switch to lactic acid fermenation. Lactic acid builds up in the muscles and creates that ___________________ feeling.
What reactant is missing from both of the equations above? ___________
MUSCLE
C6H12O LACTIC ACID
BURNING
OXYGEN
