Total questions: 15
Worksheet time: 8mins
What are the two main stages of photosynthesis?
Light-dependent reactions and light-independent reactions
Chlorophyll absorption and stomata opening
Carbon dioxide intake and oxygen release
Glucose production and water absorption
What is the role of chlorophyll in photosynthesis?
It absorbs sunlight for energy conversion
It releases oxygen into the atmosphere
It opens stomata for gas exchange
It stores glucose for plant growth
Why is oxygen important for life on Earth?
It combines with glucose to form energy
It is the main reactant in photosynthesis
It is used in respiration to release energy from food
It helps plants absorb sunlight
Which factors can affect the rate of photosynthesis?
Light intensity, carbon dioxide concentration, water availability, and temperature
Sunlight, glucose production, oxygen release, and chlorophyll levels
Carbon dioxide intake, stomata size, water absorption, and plant height
Chlorophyll amount, leaf color, soil type, and oxygen levels
How does photosynthesis contribute to food security?
It provides food at the base of food chains and sustains agricultural production
It helps plants grow taller and stronger
It increases oxygen levels in the atmosphere
It reduces carbon dioxide concentration in the air
What is the primary energy source for photosynthesis?
Carbon dioxide
Oxygen
Glucose
Sunlight
What is the function of stomata in photosynthesis?
They release oxygen into the atmosphere
They store glucose produced during photosynthesis
They absorb sunlight for energy conversion
They allow gases to enter and exit the plant
What is glucose in the context of photosynthesis?
A gas released during photosynthesis
A molecule that splits water
A type of sugar produced by plants as food
A pigment that absorbs sunlight
Where do light-dependent reactions occur?
In the stroma
In the thylakoid membranes
In the stomata
In the chlorophyll molecules
What is produced during light-dependent reactions?
Chlorophyll and stomata
Carbon dioxide and water
Glucose and oxygen
ATP and NADPH
Where does the Calvin Cycle take place?
In the stroma
In the thylakoid membranes
In the stomata
In the chlorophyll molecules
What is the role of carbon dioxide in photosynthesis?
It absorbs sunlight for energy conversion
It combines with water to form glucose
It splits water molecules
It releases oxygen into the atmosphere
What is a by-product of photosynthesis?
Oxygen
Glucose
Carbon dioxide
ATP
What happens during light-independent reactions?
ATP and NADPH are used to convert carbon dioxide into glucose
Water molecules are split to release oxygen
Sunlight is absorbed by chlorophyll
Stomata open to allow gas exchange
How can understanding photosynthesis help promote sustainability?
By advancing agriculture and renewable energy like biofuels
By eliminating carbon dioxide from the air
By reducing plant growth rates
By increasing oxygen levels in the atmosphere
