Photosynthesis Basics

What are the main plant parts involved in photosynthesis?

• Flowers

• Leaves

• Roots

• Stems

How does the leaf structure help in photosynthesis?

• The leaf structure helps in photosynthesis by producing heat instead of absorbing light

• The leaf structure helps in photosynthesis by repelling water instead of absorbing it

• The leaf structure helps in photosynthesis by having a smooth surface that reflects light away

• The leaf structure helps in photosynthesis by providing a large surface area for light absorption, containing chloroplasts where photosynthesis occurs, and having stomata for gas exchange.

Explain the role of chlorophyll in photosynthesis.

• Chlorophyll releases oxygen during photosynthesis.

• Chlorophyll is responsible for breaking down glucose in photosynthesis.

• Chlorophyll stores water for photosynthesis.

• Chlorophyll absorbs light energy during photosynthesis.

What is the function of stomata in photosynthesis?

• Stomata allow for the exchange of gases, letting in carbon dioxide and releasing oxygen during photosynthesis.

• Stomata store excess water for later use in photosynthesis

• Stomata regulate the temperature of the plant during photosynthesis

• Stomata absorb sunlight directly for photosynthesis

Name one factor that can affect the rate of photosynthesis.

• Color of the plant

• Temperature of the water

• Amount of carbon dioxide

• Intensity of light

How does light intensity impact photosynthesis?

• Light intensity impacts photosynthesis by influencing the rate at which plants can convert light energy into chemical energy.

• Plants can perform photosynthesis in complete darkness

• Higher light intensity decreases photosynthesis efficiency

• Light intensity has no impact on photosynthesis

What role does carbon dioxide play in the process of photosynthesis?

• Carbon dioxide is released by plants as a waste product during photosynthesis.

• Carbon dioxide is used by plants to produce glucose during photosynthesis.

• Carbon dioxide inhibits the production of glucose in plants during photosynthesis.

• Carbon dioxide is not involved in the process of photosynthesis.

Why is water important for photosynthesis?

• Water is used to store excess energy in photosynthesis

• Water helps in the synthesis of glucose during photosynthesis

• Water is a byproduct of the light-independent reactions in photosynthesis

• Water is needed as a reactant in the light-dependent reactions of photosynthesis to produce oxygen, protons, and electrons.

How does temperature affect the rate of photosynthesis?

• Temperature affects the rate of photosynthesis by reducing the amount of sunlight reaching the plant.

• Temperature affects the rate of photosynthesis by influencing enzyme activity.

• Temperature affects the rate of photosynthesis by increasing the amount of water available to the plant.

• Temperature affects the rate of photosynthesis by changing the color of the leaves.

Explain the relationship between photosynthesis and oxygen production.

• Photosynthesis is unrelated to oxygen production.

• Photosynthesis is the process by which animals produce oxygen.

• Photosynthesis is the process by which plants produce oxygen as a byproduct.

• Photosynthesis is the process by which plants produce carbon dioxide.
