Photosynthesis

Is photosynthesis the foundation for energy transfer in food webs?

• True

• False

• Only in aquatic ecosystems

• Only in terrestrial ecosystems

What is the word equation for photosynthesis?

• carbon dioxide + water ---> glucose + oxygen

• oxygen + glucose ---> carbon dioxide + water

• carbon + water ---> glucose + oxygen

• glucose + oxygen ---> carbon dioxide + water

What is the primary product of photosynthesis?

• Oxygen, which is released into the atmosphere.

• Glucose, which is used by plants for energy.

• Carbon dioxide, which is absorbed by plants.

• Water, which is used in the process of photosynthesis.

What role does chlorophyll play in photosynthesis?

• Chlorophyll absorbs sunlight, which is essential for the photosynthesis process.

• Chlorophyll releases oxygen as a byproduct of photosynthesis.

• Chlorophyll helps in the formation of glucose without sunlight.

• Chlorophyll is responsible for the color of the plant's roots.

Why is water important for photosynthesis?

• Water is one of the raw materials needed for the photosynthesis process.

• Water helps in the absorption of sunlight.

• Water is a byproduct of photosynthesis.

• Water is used to transport nutrients in plants.

What is the role of sunlight in photosynthesis?

• Sunlight provides the energy needed for the photosynthesis process.

• Sunlight is used to absorb carbon dioxide from the atmosphere.

• Sunlight helps in the formation of soil nutrients.

• Sunlight is necessary for the growth of roots.

What is the relationship between photosynthesis and respiration?

• Photosynthesis produces glucose and oxygen, which are used in respiration to release energy.

• Respiration produces glucose and oxygen, which are used in photosynthesis to release energy.

• Photosynthesis and respiration are unrelated processes in plants.

• Photosynthesis occurs only at night, while respiration occurs during the day.

What type of organisms perform photosynthesis?

• Primarily green plants, algae, and some bacteria.

• Only animals and fungi.

• All types of microorganisms.

• Only trees and shrubs.

Can photosynthesis occur without sunlight?

• Yes, it can occur in the dark.

• Yes, with artificial light.

• No, sunlight is essential for photosynthesis to take place.

• Only in certain conditions.

What is photosynthesis?

• The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

• A method used by animals to convert food into energy.

• The way in which plants absorb water from the soil.

• A chemical reaction that occurs only in the dark.
