Photosynthesis - 5th Grade

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the three main ingredients needed for photosynthesis?

Back

The three main ingredients needed for photosynthesis are sunlight, water, and carbon dioxide.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide from the air during photosynthesis.

Front

What gas do plants release as a byproduct of photosynthesis?

Back

Plants release oxygen as a byproduct of photosynthesis.

Front

Why is sunlight important for photosynthesis?

Back

Sunlight provides the energy required for the photosynthesis process, allowing plants to convert carbon dioxide and water into glucose.

Front

What role does water play in photosynthesis?

Back

Water is one of the key ingredients in photosynthesis; it is split into hydrogen and oxygen, with the hydrogen being used to form glucose.

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 and its role in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the significance of photosynthesis for humans and animals?

Back

Photosynthesis is crucial for humans and animals because it produces oxygen, which is necessary for respiration, and it forms the base of the food chain.

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).
