Photosynthesis

Front

What causes plants to appear green?

Back

Chlorophyll is the pigment responsible for the green color in plants, as it absorbs light primarily in the blue and red wavelengths and reflects green light.

Front

What is the goal of photosynthesis?

Back

The primary goal of photosynthesis is to convert light energy into chemical energy in the form of glucose, which plants use as food.

Front

What difficulties does a plant in the desert face in terms of photosynthesis?

Back

Plants in the desert face challenges in obtaining and retaining the water needed for photosynthesis due to the arid environment.

Front

Which organism would be most likely used to study the effect of water on photosynthesis rates?

Back

Corn is a common plant used in experiments to study the effects of water on photosynthesis due to its well-understood biology and growth conditions.

Front

What causes different leaf colors in the fall?

Back

The different leaf colors in the fall are caused by a decreased concentration of chlorophyll, which allows other pigments like carotenoids to become visible.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions in photosynthesis, particularly in the light-dependent reactions.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that plays a crucial role in absorbing light energy for photosynthesis.
