7.5A - Photosynthesis

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 main reactants needed for photosynthesis?

Back

The main reactants needed for photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

Which organelle is responsible for photosynthesis in plant cells?

Back

The chloroplast is the organelle inside a plant cell where photosynthesis takes place.

Front

What pigment absorbs sunlight in plants?

Back

Chlorophyll is the pigment in plants that absorbs sunlight and reflects green light.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is: CO2 + H2O --> (in sunlight) C6H12O6 + O2.

Front

What does the arrow in a chemical equation represent?

Back

The arrow in a chemical equation means 'yields' or indicates the direction of the reaction.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process to convert carbon dioxide and water into glucose and oxygen.

Front

What is glucose and why is it important for plants?

Back

Glucose is a simple sugar produced during photosynthesis that serves as an energy source for plants and is used for growth and development.

Front

What is the byproduct of photosynthesis?

Back

The byproduct of photosynthesis is oxygen (O2), which is released into the atmosphere.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the air through small openings in their leaves called stomata.
