Photosynthesis and Respiration Study Guide
Photosynthesis
- Why? To convert sunlight energy to chemical energy
- Whom?
1. All green plants (Plant Kingdom),
2. photosynthetic bacteria,
3. plant-like protists (algae)
- Where? Leaves(organs), specifically chloroplasts
- When? During daylight/sunlight (even on a cloudy day)
- What? Chloroplasts [are making food/glucose]; “Mean green photosynthesizing machines”
Define Photosynthesis. “The Putting Together With Light”
- Producers/autotrophs - organisms that can make their own food.
- We get so much from the process of photosynthesis: food, clothing medicines, wood, oxygen, paper, pencils, flowers, and so much more!
Respiration/Aerobic Respiration
- Why To produce ATP
- Whom? All aerobes (organisms that use oxygen); producers and consumers
1. Plants
2. Animals
3. Some bacteria
4. Protists
5. Some fungi
- Where? Mitochondria
- When? Constantly
- What? Food/glucose is being broken down to release energy
Define respiration. The metabolic processes whereby certain organisms obtain energy from organic molecules; processes that take place in the cells and tissues during which ATP energy is released and carbon dioxide and water is produced.
Fermentation/Anaerobic Respiration
- Why? To produce ATP
- Whom? All anaerobes (organisms that do not use oxygen)
1. Yeast/fungi
2. Some bacteria
- Where? Cytoplasm
- When? Constantly
- What? Food/glucose [is being fermented]
Define fermentation. Fermentation is a process by which food is broken down
without oxygen, in living organisms, to produce ATP.
- What industries use fermentation?
1. Baking (CO2)
2. Brewing (Alcohol and CO2)
3. Dairy (Lactic Acid)
- What are the reactants ? One sugar (C6H12O6) (and a ATP investment).
- What are the products of fermentation? ATP and [CO2, alcohol] OR [ lactic acid]
Consumers/heterotrophs - organisms that must obtain food sources from other organisms.
- Herbivores - eat only plants
- Carnivores - eat only meat
- Omnivores - eat both plants and meat
- Scavengers - organisms that eat dead organisms
- Decomposers/Detritivores - Break down organisms, “nature’s recyclers”
- Arrows point towards the organism obtaining energy or eating!
Metabolism - The chemical processes that occur within a living organism in order to maintain life.
Enzymes - Help speed up chemical processes by breaking substances apart or putting substances together.
- Use my blog, review worksheets and other assignments
- Use the textbook, pgs. 83-87

Where Do I Get Energy?
Internet Webquest Activity
Directions: Navigate the websites and collect information for each section of this webquest activity. Please make sure you write your responses in complete sentences and apply care and color in your drawings/sketches.
A. Photosynthesis Animation
1. What do plants take in through the roots? _____________________________________
2. What moves up stems to the leaves? ____________________________________________
3. Where does the leaf get water? _________________________________________________
4. Where does the leaf get carbon dioxide? _______________________________________
5. What does the leaf combine to make sugar? ____________________________________
6. What does the plant release into the air as a waste? ____________________________
7. What does the plant do with the sugar it makes? ________________________________
8. Why are plants important to the environment? __________________________________
B. Introduction to Photosynthesis - Illuminating Photosynthesis
