- What is this organelle and what process occurs in it?
Chloroplast
Photosynthesis
- What is the equation for cellular respiration?
REACTANTSPRODUCTS
C6 H12 O6 + 6O2 6CO2 + 6 H2 O + 36 ATP
glucose oxygen enzymes carbon water energy
- What is the equation for photosynthesis?
REACTANTSPRODUCTS
6CO2 + 6 H2O + Sun C6 H12 O6 + 6O2

dioxide
- What is the relationship between cellular respiration and photosynthesis?
They both transform energy
The reactants of one equal the products of the other (flipped
PRODUCTS = REACTANTS
- What are the two types of cellular respiration?
Anaerobic (without oxygen)-yeast and some bacteria
Aerobic (needs oxygen)-animals and plants
- What are the two kinds of anaerobic respiration and their products?
Alcoholic fermentation in yeast
(products: ethanol (ethyl alcohol) and carbon dioxide and 2 ATP
Lactic acid fermentation in animal muscles
(products: lactic acid and 2 ATP
- What do plants use to make food? (=reactants)
CO2, H2O, and sun (radiant) energy
- What do plants make that heterotrophs need? (= products)
C6H12O6 (glucose) and O2
- What is the purpose of cellular respiration?
To make usable energy for the cells (ATP)
- What do animals and plants need for respiration? (reactants)
They use glucose and oxygen from photosynthesis
- What are the products of cellular respiration?
CO2, H2O, and ATP
(These are what plants need for photosynthesis)
- In this experiment, what gas bubbles are present? What process is occurring?
Oxygen
- If the plant is producing these bubbles, then what is being made?
Glucose
- What color would bromethymol blue be in this experiment?
Blue
- If you blew in a flask of a bromethymol blue solution, what color would it change to? Why?
Yellow-indicates the presence of carbon dioxide
- What are limiting factors of the rate of photosynthesis?
Carbon dioxide, water, light, temperature
- In this diagram, is more glucose made in low or high temperature? Light?
High temperature and stronger light intensity
- Indicate what number represents the site of photosynthesis?
7 chloroplasts
- In the diagram above, what would move into the cell during photosynthesis?
CO2, H2O, and sun (solar or radiant) energy
- Within the leaf, the guard cells regulate the gas exchange through the stoma (also stomate; plural stomata). Indicate the gases and direction of movement in a plant.
CO2 IN (photosynthesis)
O2 OUT (photosynthesis)
H2O vapor OUT (transpiration)
- How do the animal and plant vascular systems compare?
Arteries and veins of the animal work similarly to the xylem and phloem of the plant.
Xylem: transport water from root up through plant (all end of alphabet)
Phloem: transport food, glucose, down from leaf to rest of plant (beginning of alphabet); phloem-food (f-sounding)
- What is the usable energy of the cell that an animal uses for metabolic processes?
ATP
- In the following images, what are the products of the bioenergetic relationships?

- Which type of respiration is more efficient? Why?
Aerobic respiration is more efficient because it creates 36 ATP
Anaerobic respiration (no oxygen) only produces 2 ATP
