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