Total questions: 10
Worksheet time: 5mins
What is the primary function of photosynthesis?
To store energy in the form of fat.
To release oxygen as a waste product.
To absorb carbon dioxide from the atmosphere.
The primary function of photosynthesis is to convert light energy into chemical energy in the form of glucose.
Which organisms are known to perform photosynthesis?
Mushrooms, yeast, and worms.
Fungi, viruses, and mammals.
Insects, reptiles, and amphibians.
Plants, algae, and some bacteria.
What are the main products of photosynthesis?
Nitrogen and glucose
Oxygen and carbon monoxide
Glucose and oxygen
Carbon dioxide and water
In which part of the plant does photosynthesis primarily occur?
Flowers
Roots
Leaves
Stems
What pigment is essential for photosynthesis?
Carotene
Melanin
Chlorophyll
Xanthophyll
What is the role of sunlight in photosynthesis?
Sunlight is essential for photosynthesis as it provides the energy needed for the conversion of carbon dioxide and water into glucose and oxygen.
Sunlight is only needed for plant growth, not photosynthesis.
Sunlight is used to absorb nutrients from the soil.
Sunlight is harmful to plants during photosynthesis.
What are the two main stages of photosynthesis?
Photosynthesis and respiration
Light absorption and energy storage
Light-dependent reactions and light-independent reactions (Calvin cycle)
Chlorophyll activation and glucose production
How does carbon dioxide enter the plant?
Carbon dioxide enters through flowers.
Carbon dioxide enters the plant through stomata.
Carbon dioxide enters through roots.
Carbon dioxide is absorbed by leaves directly.
What is the chemical equation for photosynthesis?
6CO2 + 6H2O -> C6H12O6 + 6O2 + heat
C6H12O6 + 6O2 -> 6CO2 + 6H2O + light energy
6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
6O2 + 6H2O + light energy -> C6H12O6 + 6CO2
Why is photosynthesis important for life on Earth?
Photosynthesis decreases the amount of carbon dioxide in the atmosphere.
Photosynthesis is important because it produces oxygen and is the primary source of energy for ecosystems.
Photosynthesis is a process that occurs only in animals.
Photosynthesis is primarily responsible for the formation of soil.
