Plants & Energy Review

What is the definition of photosynthesis?

• Photosynthesis occurs only in animals during the night.
• Photosynthesis is the process by which organisms convert light energy into chemical (glucose) energy.

• Photosynthesis is the method by which plants absorb nutrients from the soil.
• Photosynthesis is the process of converting chemical energy into light energy.

Why are the plants green?

• chlorophyll absorbs green light

• chlorophyll reflects green light

• because plants are full of green nutrients

• because chlorophyll is green

What is the job of chlorophyll?

• Chlorophyll helps in water absorption.
• The job of chlorophyll is to absorb light energy for photosynthesis.
• Chlorophyll is responsible for plant respiration.
• Chlorophyll protects plants from pests.
