- Q1
How do plants obtain energy for photosynthesis?
Carbon dioxide is absorbed through the roots
Sunlight is absorbed by the leaves
Water is absorbed through the roots
Oxygen is absorbed through the leaves
60s - Q2
In which way are photosynthesis and cellular respiration different?
Cellular respiration produces oxygen, while photosynthesis uses oxygen.
Photosynthesis releases energy, while cellular respiration stores energy.
Cellular respiration stores ATP, while photosynthesis releases ATP.
Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
120s - Q3
Which of the following represents the correct cycling of gases?
120s - Q4
Which statement best describes a relationship between mitochondria and chloroplasts?
Chloroplasts convert light energy into chemical energy that can be used by mitochondria.
Mitochondria convert chemical energy into light energy that can be used by chloroplasts.
Mitochondria release chemical energy from molecules and store it in chloroplasts.
Chloroplasts release chemical energy from molecules and store it in mitochondria.
60s - Q5
Four students classified the main energy conversions that occur during photosynthesis and cellular respiration. Which student best classified the energy conversions that occur in the two processes?
student 1
student 4
student 2
student 3
120s - Q6
A cell in the leaf of a green plant performs both photosynthesis and cellular respiration, often at the same time. Which statement best describes how these processes are related to each other?
Both processes produce carbon dioxide.
Both processes require energy directly from the Sun.
Thermal energy from one process is used as the energy source for the other process.
Products of one process are used as some of the reactants for the other process.
60s - Q7
An organism carries out both photosynthesis and cellular respiration. Which statement describes a difference between these two processes?
The processes occur at different times during the animal’s life cycle.
The processes occur in different types of animal cells.
Only photosynthesis changes light energy into chemical energy.
Only cellular respiration creates chemical energy.
120s - Q8
Which statement best describes both mitochondria and chloroplasts?
They both contain their own DNA and are involved in energy conversions.
They both contain their own RNA and are involved in transcription.
They both contain their own DNA and are involved in controlling the activities of a cell.
They both contain their own RNA and are involved in storage of nuclear genetic material.
120s - Q9
The process that releases energy (ATP) by breaking down glucose. (converts food molecules (glucose) into a form usable (ATP) by the organism)
cellular respiration
photosynthesis
60s - Q10
Based upon the equation shown, how many molecules of Carbon Dioxide (CO2) and water (H2O) are required to make one molecule of glucose (C6H12O6) as a result of photosynthesis?
Photosynthesis requires 12 CO2 + 2 H2O molecules to create 1 molecule of glucose
Photosynthesis requires 6 CO2 + 6 H2O molecules to create 1 molecule of glucose
Photosynthesis requires 4 Carbon, 12 Oxygen, and 6 Hydrogen atoms to create 1 molecule of glucose
Photosynthesis requires 12 Oxygen and 6 Hydrogen atoms to create 1 molecule of glucose
120s - Q11
How is cellular respiration different from photosynthesis?
photosynthesis produces oxygen, cellular respiration produces carbon dioxide
photosynthesis requires oxygen, cellular respiration requires oxygen
photosynthesis requires energy from food, cellular respiration requires energy from the sun
photosynthesis produces ATP, cellular respiration produces sugars
120s - Q12
In which way are photosynthesis and cellular respiration different?
Cellular respiration produces oxygen, while photosynthesis uses oxygen.
Cellular respiration stores ATP, while photosynthesis releases ATP.
Photosynthesis releases energy, while cellular respiration stores energy.
Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
120s - Q13
How can energy from the sun be transferred to animals?
Plants produced energy through photosynthesis, animals that eat that energy can produce food.
The sun's energy is transformed into food by plants, animals eat plants as food so that they can transform that food into energy.
Animals are able to use energy from the sun by eating the plants that provides energy for the animals.
Plants transformed energy of the sun into gases that animals can breath in to use as energy through respiration.
120s - Q14
What is the correct equation for photosynthesis?
6O2 + C6H12O6 ---> 6CO2 + 6H2O + Energy
6CO2 + 6H2O ---> 6O2 + C6H12O6 + Energy
6O2 + 6C6H12O6 + Energy ---> 6CO2 + 6H2O
6CO2 + 6H2O + Energy ---> 6O2 + C6H12O6
120s - Q15
What is the correct equation for cellular respiration?
6O2 + C6H12O6 ---> 6CO2 + 6H2O + Energy
6CO2 + 6H2O ---> 6O2 + C6H12O6 + Energy
6O2 + C6H12O6 + Energy ---> 6CO2 + 6H2O
6CO2 + 6H2O + Energy ---> 6O2 + C6H12O6
