Front

What is the main source of energy for all life?

Back

The sun.

Front

Why do most plants appear green?

Back

Because chlorophyll reflects green light.

Front

What does chlorophyll not absorb?

Back

Green light.

Front

What sets heterotrophs apart from autotrophs?

Back

Heterotrophs obtain food from consuming other living or once-living things.

Front

During which stage of photosynthesis do plants need carbon dioxide to produce glucose?

Back

The light-independent stage (The Calvin Cycle).

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What are autotrophs?

Back

Organisms that produce their own food using sunlight or chemical energy.

Front

What are heterotrophs?

Back

Organisms that cannot produce their own food and must consume other organisms.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and light-independent reactions (Calvin Cycle).
