What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What is respiration in living organisms?

Back

Respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. It occurs in all living organisms.

Front

What role does Elodea play in aquatic ecosystems?

Back

Elodea is an aquatic plant that provides oxygen and habitat for aquatic life, and it plays a crucial role in the process of photosynthesis.

Front

What is the significance of carbon dioxide (CO2) in photosynthesis?

Back

Carbon dioxide is one of the key reactants in photosynthesis, as it is used by plants to produce glucose and oxygen.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis, up to a certain point, after which other factors may become limiting.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in respiration to produce energy, while respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What happens to CO2 levels in a test tube with only Elodea when exposed to light?

Back

CO2 levels decrease as Elodea performs photosynthesis, using CO2 to produce glucose and releasing oxygen.

Front

What is the expected outcome for CO2 levels in a test tube with only snails when the lights are on?

Back

The amount of CO2 would increase and O2 would decrease, as snails respire, consuming oxygen and producing carbon dioxide.

Front

What is the role of light in photosynthesis?

Back

Light provides the energy needed for photosynthesis to occur, enabling plants to convert CO2 and water into glucose.

Front

What is the effect of temperature on the rate of photosynthesis?

Back

Temperature can affect the rate of photosynthesis; too low or too high temperatures can slow down or inhibit the process.
