Photosynthesis And Respiration
Test Description: Respiration and Photosynthesis practice
Instructions: Answer all questions to get your test result.
1) What happens during photosynthesis?
A
sugar and water combine with oxygen to form energy
B
water and sugar form energy in the mitochondria
C
carbon dioxide and water combine with sunlight to form glucose and oxygen
D
oxygen and sugar combine to form energy
2) How does photosynthesis benefit other organisms such as heterotrophs?
A
photosynthesis has nothing to do with heterotrophs
B
photosynthesis allows plants to grow so heterotrophs have something to eat and oxygen to breathe
C
heterotrophs get energy from the sun
D
photosynthesis allows plants to move
3) What happens during respiration?
A
sugar and water combine with oxygen to form energy
B
oxygen and sugar combine to form energy in the leaf
C
water and sugar form ATP energy in the mitochondria
D
carbon dioxide and water combine with sunlight to form glucose and oxygen
4) Where is most of the energy in glucose released during cellular respiration?
A
mitochondria
B
chloroplast
C
cytoplasm
D
chlorophyll
5) How are photosynthesis and respiration related?
A
They are opposites
B
They are the exact same thing
C
they have nothing to do with each other
D
they are the same thing but one has to do with gasses and the other has to do with water
6) What happens during respiration?
A
sunlight is absorbed
B
ATP is made
C
sunlight is made
D
glucose is made
7) What happens to the levels of carbon dioxide and oxygen in the atmosphere because of respiration and photosynthesis?
A
there is more CO2
B
They balance out
C
There is more O2
D
There is no air
8) What is the energy-releasing process that does not require oxygen is called?
A
alcohol
B
photosynthesis
C
fermentation
D
lactic acid
9) What type of conditions cause lactic-acid fermentation?
A
the cells run out of water
B
cells die
C
you will never recover
D
cells do not get oxygen fast enough
10) What role does chlorophyll have in the process of photosynthesis?
A
it hides the sun
B
it fills the cell
C
it repels the sun
D
it absorbs the sun
11) How does carbon dioxide enter plant?
A
through the flower
B
through the stomata
C
through the stem
D
through the chloroplast
12) What is the process of respiration that does not require oxygen and produces alcohol as a bi-product?
A
respiration
B
alcoholic fermentation
C
lactic acid fermentation
D
photosynthesis
13) What is the chemical formula for photosynthesis? (words)
A
Sunshine + water + carbon dioxide yields carbon dioxide and water
B
Water + glucose + oxygen yields glucose + carbon dioxide + water
C
Oxygen + water yields glucose + carbon dioxide + water
D
Carbon dioxide + water + sunshine yields glucose + Oxygen + water
14) What is the main difference between respiration and fermentation?
A
fermentation moves water
B
fermentation never happens outside of bacteria
C
there is no difference
D
respiration requires oxygen and fermentation doesn't
