Photosynthesis in Plants Questions
Which marine organism is responsible for producing oxygen through photosynthesis?
-
Phytoplankton
-
Zooplankton
-
Coral
-
Seaweed
A
Correct answer
Explanation
Phytoplankton are microscopic algae that perform photosynthesis, producing oxygen and absorbing carbon dioxide.
What is the term for the process by which plants convert sunlight into energy?
-
Photosynthesis
-
Cellular respiration
-
Fermentation
-
Glycolysis
A
Correct answer
Explanation
Photosynthesis is the process by which plants convert sunlight into energy. It is a vital process for life on Earth, as it provides the food and oxygen that all living things need to survive.
What is the primary source of energy for photosynthesis in plants?
-
Ultraviolet radiation
-
Visible light
-
Infrared radiation
-
X-rays
B
Correct answer
Explanation
Visible light is the primary source of energy for photosynthesis in plants, as it is absorbed by chlorophyll molecules in the plant's leaves.
