4. During the processes of photosynthesis and cellular respiration energy is converted. The law of conservation of energy is observed. Which cell organelles are involved in converting energy from one form to another? (1 point)
• nucleus and cytoplasm
• cell membrane and golgi body
• chloroplasts and mitochondria
• Ivsosomes and ribosomes
The correct answer is chloroplasts and mitochondria.
5. Plants use the solar energy in sunlight to drive photosynthesis and produce glucose. The energy stored in the glucose is then released by the process of _. (1 point)
• protein synthesis
• genetic engineering
• photosynthesis
cellular respiration
The correct answer is cellular respiration.
6. Jaylah and Simon were discussing what they learned in Science class today. Jaylah asked Simon the following question, "If oxygen is removed from a plant's environment, what would you expect to happen to the plant's ability to break down glucose sugar and produce the energy molecule of ATP?"
What is the correct response that Simon should give Jaylah?
(1 point)
The plant's ability to break down glucose sugar and produce the energy molecule of ATP would not be affected because
photosynthesis should occur normally.
The plant's ability to break down glucose sugar and produce the energy molecule of ATP would not be affected because cellular respiration should occur normally.
o The plant's ability to break down glucose sugar and produce the energy molecule of ATP would be affected because cellular
respiration would not have a needed reactant to undergo all the chemical reactions.
The plant's ability to break down glucose sugar and produce the energy molecule of AT would be affected because photosynthesis would not have a needed reactant to undergo all the chemical reactions.
The correct response that Simon should give Jaylah is:
"The plant's ability to break down glucose sugar and produce the energy molecule of ATP would be affected because cellular respiration would not have a needed reactant to undergo all the chemical reactions."
7. Match the parts of the photosynthesis equation.
6C0, +64,0-7664186 + 602
carbon dioxide + water --> glucose + oxygen
water - reactant or product
glucose - reactant or product
oxygen - reactant or product
carbon dioxide - reactant or product
In the photosynthesis equation:
6CO2 + 6H2O -> C6H12O6 + 6O2
water - reactant
glucose - product
oxygen - product
carbon dioxide - reactant
