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 of photosynthesis?

Back

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

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C6H12O6), which is used by plants for energy.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for photosynthesis to occur, enabling plants to convert carbon dioxide and water into glucose.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light or chemical energy. Examples include plants and some bacteria.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must obtain energy by consuming other living or once-living organisms. Examples include animals and fungi.

Front

What is chlorophyll?

Back

Chlorophyll is the green pigment found in plants that absorbs light energy for photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

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.

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.
