Protist/Fungi and
Photosynthesis/Cellular Respiration
Review
1. Name one thing protists and bacteria have in
common. Name two things that are different about
protist and bacteria.
• 1 thing….. Cell walls? Cilia? Flagella? How
they reproduce?
• 2 things…. Protists may be single-celled
organisms or multicelled. Bacteria are only
single-celled. Bacteria have no membrane
bound organelles, protists have nuclei and
other organelles. Protists are eukaryotic, while
bacteria are prokaryotic
2. How are protists classified? How do fungi-like protists get their
nutrients? How do plant-like protists get their nutrients? How
do animal-like protists get their nutrients?
• Protists are classfied by how they get their
food. (plant-like (photosynthesis), animal-like
(heterotrophs), Fungi-like (heterotrophs that
absorb their food.)
3. What are flagella? What are cilia?
Flagella are whip-like
structures used for movement.
Cilia are tiny hair-like
projections that are used for
movement.
4. List four characteristics of fungi. What important role do
fungi play for our environment?
• 4 characteristics of
fungi…
– Heterotrophic
– Reproduce by spores
– Cell walls made of
CHITIN
– Eukaryotic
– Multicellular
• Fungi are
DECOMPOSERS or
SAPROBES
5. What are three things that plants and fungi have in
common?
• 3 things that plants and fungi have in
common…..
– Eukaryotic
– Have cell walls
– multicellular
6. Define autotroph. Define heterotroph.
Autotroph – make their own
food
Heterotroph – get their food
from consuming or absorbing
other organisms.
7. What is ATP? How is energy released from ATP?
Explain why it can be said that ATP is a reusable
battery?
• ATP: The molecule
of energy
• Energy is released
from the bond
between the 2nd
and 3rd phosphate.
• ATP is constantly
recycled from ADP
8. Explain the process of photosynthesis. Write out the
chemical equation.
9. What are the reactants needed for photosynthesis?
What are the products?
REACTANTS
PRODUCTS
10. Where do the reactants needed for photosynthesis come
from? How are the products of photosynthesis used?
11. In what organelle does photosynthesis occur? Do both
plants and animals perform photosynthesis?
• ONLY plants and bluegreen algae undergo
photosynthesis.
12. What are three factors that can affect the rate of
photosynthesis?
• Amount of light
• Available water
• Available CO2
13. What most likely caused the formation of bubbles?
• Oxygen….
• The plant used the CO2
in the flask to create
oxygen.
14. What is cellular respiration? Write out the chemical
equation.
15. What are the reactants needed for cellular
respiration? What are the products?
REACTANTS
PRODUCTS
16. Where do the reactants needed for cellular respiration
come from? How are the products of cellular respiration
used?
•Reactants: Come from food, air and water
•Products: are used for energy and as waste
17. In what organelle does cellular respiration occur?
Do both plants and animals perform cellular
respiration?
• Mitochondria
• BOTH plants and
animals perform cellular
respiration.
18. Why is cellular respiration called an aerobic process? What
process will the body enter into if there is not enough oxygen to
meet the demand?
• It’s called an Aerobic
process because
OXYGEN is needed.
• Without Oxygen, the
process shifts to
Anaerobic
Fermentation.
19. 1 molecule of glucose will make ___36______ molecules
of ATP during cellular respiration.
20. Explain why it is said that cellular respiration and
photosynthesis are almost opposite processes?
21. Photosynthesis and cellular respiration help to cycle
____CO2___, ____WATER______, and ____OXYGEN______
through ecosystems
22. Photosynthesis ____creates_______ energy and Cellular
respiration ______releases_________ energy.
