10 Questions
What is the word equation for photosynthesis?
Carbon dioxide + water $\rightarrow$ glucose + oxygen
Where does the hydrogen come from that combines with carbon dioxide in photosynthesis?
From the splitting of water molecules
What is the waste product released through stomata in the underside of the leaves during photosynthesis?
Oxygen
What is the substance formed after the reaction takes place in photosynthesis?
Glucose
What do plant cells break down glucose for?
Cellular respiration
What are the roles of light, carbon dioxide, water, and chlorophyll in photosynthesis?
Light is used to provide energy, chlorophyll captures light, carbon dioxide is used as a carbon source, and water is split to release oxygen and provide electrons for the synthesis of glucose.
What is the primary function of chloroplasts in photosynthesis?
To contain chlorophyll which captures light energy to create oxygen and sugar.
How do autotrophs and heterotrophs differ in obtaining energy?
Autotrophs make food and store it within themselves, while heterotrophs consume or absorb food from other organisms.
What is the process by which cells capture energy in sunlight to make food (glucose)?
Photosynthesis
What is the distinction between active transport and passive transport in cells?
Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.
Test your knowledge of cell biology and photosynthesis with questions about active and passive transport, the roles of light, carbon dioxide, water, and chlorophyll in photosynthesis, and the significance of photosynthesis in ecosystems.
