LS Photosynthesis and CR test

Front

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.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which living organisms convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light or chemical energy.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose (C6H12O6), which serves as an energy source for plants.

Front

What is the main byproduct of cellular respiration?

Back

The main byproduct of cellular respiration is carbon dioxide (CO2), which is released into the atmosphere.

Front

How do plants obtain carbon dioxide?

Back

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