Total questions: 10
Worksheet time: 5mins
What is photosynthesis?
Photosynthesis occurs only in the presence of water vapor.
Photosynthesis is the method by which plants absorb nutrients from the soil.
Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose.
Photosynthesis is the process of respiration in animals.
Which organisms primarily perform photosynthesis?
Plants, algae, and some bacteria
Fungi and viruses
Mammals and reptiles
Insects and arachnids
What are the main ingredients needed for photosynthesis?
Carbon monoxide, water, and soil
Sunlight, nitrogen, and minerals
Sunlight, carbon dioxide, and water
Oxygen, nitrogen, and glucose
What is the role of sunlight in photosynthesis?
Sunlight is only needed for plant growth, not photosynthesis.
Sunlight is a byproduct of photosynthesis.
Sunlight is essential for photosynthesis as it provides the energy required for the conversion of carbon dioxide and water into glucose.
Sunlight cools the plant during photosynthesis.
What gas do plants take in during photosynthesis?
carbon dioxide
hydrogen
oxygen
nitrogen
What gas do plants release as a byproduct of photosynthesis?
Methane
Oxygen
Carbon Dioxide
Nitrogen
In which part of the plant does photosynthesis mainly occur?
Stems
Leaves
Flowers
Roots
What is chlorophyll and why is it important for photosynthesis?
Chlorophyll is a type of carbohydrate that stores energy for plants.
Chlorophyll is a gas released during photosynthesis.
Chlorophyll is a mineral that helps in soil formation.
Chlorophyll is a pigment essential for photosynthesis, as it absorbs light energy to convert carbon dioxide and water into glucose and oxygen.
How does photosynthesis benefit the environment?
Photosynthesis benefits the environment by reducing carbon dioxide levels, producing oxygen, and supporting the food chain.
Photosynthesis increases carbon dioxide levels.
Photosynthesis produces harmful gases.
Photosynthesis eliminates all forms of pollution.
Can photosynthesis occur without sunlight? Why or why not?
No, photosynthesis cannot occur without sunlight.
Yes, photosynthesis can occur in the dark with stored energy.
Photosynthesis requires only carbon dioxide and water, not sunlight.
Photosynthesis can happen with artificial light sources only.
