Total questions: 20
Worksheet time: 10mins
What organisms use the oxygen produced during photosynthesis?
Animals and most other organisms that perform cellular respiration
Plants only
Decomposers only
Bacteria only
What does the process of photosynthesis produce?
Glucose (sugar) and oxygen
Carbon dioxide and water
ATP and lactic acid
Nitrogen gas and minerals
Which plant pigment traps most of the light energy used in photosynthesis?
Chlorophyll
Carotene
Melanin
Hemoglobin
What are carbon dioxide (CO2) and water (H2O) converted into as a result of photosynthesis?
Glucose and oxygen
Nitrogen and minerals
Alcohol and lactic acid
Starch and nitrogen gas
During photosynthesis, producers convert energy from the sun into what?
Chemical energy stored in sugar
Thermal energy released as heat
Mechanical energy for movement
Nuclear energy in the nucleus
Explain how light energy is transformed into chemical energy during photosynthesis.
Chlorophyll absorbs light that powers reactions to build glucose from carbon dioxide and water
Sunlight warms leaves so sugars melt into the plant cells
Light pushes water through roots, creating energy directly
Sunlight splits oxygen into nitrogen that becomes sugar
What are the organelles that use sunlight to produce food in the process of photosynthesis?
Chloroplasts
Mitochondria
Ribosomes
Nuclei
Photosynthesis uses sunlight to produce sugar. What kind of energy transformation is this?
Light energy to chemical energy
Chemical energy to light energy
Mechanical energy to thermal energy
Electrical energy to mechanical energy
Describe the process of photosynthesis. Use academic vocabulary.
Chloroplasts use light to convert carbon dioxide and water into glucose and oxygen
Mitochondria use oxygen to break down glucose into carbon dioxide and water
Roots absorb minerals to turn nitrogen into proteins for the plant
Leaves release water vapor to cool the plant without making sugar
Photosynthesis begins with reactants and ends when the products are created. Which chemical equation correctly shows the reactants and products of photosynthesis? Also identify which side has the reactants and which has the products.
6CO2+6H2OlightC6H12O6+6O2 ; reactants on the left and products on the right
C6H12O6+6O2→6CO2+6H2O ; reactants on the right and products on the left
6O2+6H2O→C6H12O6+6CO2 ; reactants on the right and products on the left
6CO2→C6H12O6 ; reactants and products are mixed on both sides
The plant captures light energy from the sun and uses it to convert carbon dioxide and water into food. The process of producing food in plants is known as what?
Photosynthesis
Cellular respiration
Transpiration
Germination
Photosynthesis could not occur without what?
Light energy from the sun
Nitrogen from the soil
Glucose in the chloroplasts
Minerals dissolved in xylem
What can cellular respiration not occur without?
Oxygen
Sunlight
Chlorophyll
Nuclear energy
What is an important connection between breathing and cellular respiration?
Oxygen inhaled is used to release energy from food and carbon dioxide produced is exhaled
Breathing supplies light needed to make glucose in mitochondria
Air entering the lungs becomes glucose that cells absorb
Breathing removes oxygen so cells can perform photosynthesis
What are C6H12O6 (glucose) and O2 (oxygen) converted into in cellular respiration?
Carbon dioxide, water, and usable energy (ATP)
Sugar and oxygen
Lactic acid and alcohol with no energy released
Starch and oxygen stored in chloroplasts
Overall, the process of cellular respiration releases ______ from ______.
energy from glucose (food)
oxygen from the air
light from chlorophyll
nitrogen from proteins
Identify the conversion made by the process of respiration.
Chemical energy in glucose to usable energy in ATP
Light energy to chemical energy in sugar
Mechanical energy to heat energy
Electrical energy to sound energy
During cellular respiration, glucose reacts with oxygen to produce water and carbon dioxide. Where in the cell does this reaction take place?
Mitochondria
Chloroplasts
Ribosomes
Nucleus
What is the difference between aerobic respiration and anaerobic respiration?
Aerobic uses oxygen; anaerobic does not
Aerobic happens only in plants; anaerobic happens only in animals
Aerobic makes no ATP; anaerobic makes more ATP
Aerobic uses sunlight; anaerobic uses darkness
What happens to carbohydrates during cellular respiration?
They are broken down to release energy for the cell
They are combined to store energy as fat
They are excreted unchanged from the cell
They are converted into light energy in mitochondria
