3. ___________________________________
Definition: The movement of molecules through a membrane using ___________.
Photosynthesis
Definition: The process by which plants and some bacteria, use energy from _________________ to
produce _____________.
How does the plant get:
Water?
Plants suck up water through their _______________, and let the water flow out through the
_______________.
CO2?
Plants let ____ and _____ in and out through little openings under their leaves called
_________________.
Sunlight?
The process of photosynthesis takes place in the ___________________, specifically using
___________________, the green pigment involved in photosynthesis.
Why Green? (why not purple leaves? or pink with blue stripes?)

_____________________, the green pigment in Chloroplasts, absorbs all wavelengths
of light except _______________, which is reflected to our eyes.
Why do the leaves lose the green?

As the ________________ in leaves decays in the autumn, the green color fades and is
replaced by the ____________________ of carotenoids (other pigments covered by the
green chlorophyll)
What does the plant do to break the glucose into energy?
Answer: ______________________
Respiration
During respiration, _________________ reacts with ____________ to produce _____________.
Energy is needed for growth, repair and movement.
____________ and ___________________ are bi-products of respiration - they need to be excreted.
Respiration: is the release of _____________ from glucose or another organic chemical.
Aerobic: Respiration requires _______________.
Anaerobic: Respiration does not require ___________ and releases less ____________.
Breathing: act of pulling ______ in/out.
Where does respiration occur?
In plants: ____________________________
In animals: ___________________________
Glycolysis (outside mitochondria): When glucose enters the cell, it is broken down into
smaller molecules.
Respiration: Those smaller molecules are taken in by the mitochondria, and with
_____, are turned into ______ (energy)
Types of Respiration
1. Aerobic Respiration: The use of ______ to break the _____________ into ______ (energy)
► Lots of ____________ is released by this process.
Glucose + ________________ = ___________________ + Water + Energy
2. Anaerobic Respiration: the release of energy from ___________ in the absence of __________.
► Produces a litle bit of _______________________.
There are 2 types of Anaerobic Respiration/Fermentation:
1. ______________________ Fermentation
2. ______________________ Fermentation
Lactic Acid Fermentation
 Glucose is incompletely metabolized into ____________ or CO2 and alcohol.
 The side effects of Lactic Acid Fermentation is Muscle Fatigue, _______, Cramps, and
you feel ____________________.
Alcoholic Fermentation
 Occurs in ___________ and some single-celled organisms.
 Sugar → _________________ + ______________
