Opening Activity: What is the equation for photosynthesis?
Latin Root Word:
Review of Old Information:
Review of Old Information:
1. All energy begins as what type of energy and from where?
2. What structure absorbs this energy in the plants cell? In other words, where is photosynthesis
occurring in the plant?
3. Ultimately, what is the product of photosynthesis used by plants and other consumers? What type
of energy is this?
4. Are plants autotrophs or heterotrophs?
New Information:
You learned in the last few sections that all energy comes from the sun. Plants take that light
energy and transfer it into chemical energy by storing it in the bonds of macromolecules like
carbohydrates, proteins, and lipids. Heterotrophs like ourselves are not able to do this on our own, so we
must eat those plants and the energy from plants eaten by other animals to survive. When we consume
food, we take the energy stored in those macromolecules and turn it into ATP, which is the source of
energy for our cells. This process is known as _______________ _______________.
Cellular Respiration Notes:
• The process by which mitochondria break down _______________ to make _______________.
• Two types
o Aerobic respiration: requires oxygen and carried out by plants, animals, and some bacteria
o Anaerobic respiration (also known as “fermentation”): requires no oxygen and carried out by yeast,
some bacteria, and sometimes animals
Chemical equation for aerobic respiration:
C6H12O6 + 6O2 6CO2 + 6H2O + chemical energy
(glucose + oxygen carbon dioxide + water + ATP)
