5.1 & 5.2 FLASHCARD

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll functions in changing light energy to chemical bond energy.

Front

What are heterotrophic organisms?

Back

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

Front

How does the rate of photosynthesis relate to increasing light intensity?

Back

The rate of photosynthesis increases with increasing light intensity, up to a certain point, after which it levels off.

Front

What are stomates and their role in plants?

Back

Stomates are openings on the leaves of green plants that allow for gas exchange between the leaf and the outside environment.

Front

What gas moves into the leaf through stomates on a sunny day?

Back

Carbon dioxide moves into the leaf through stomates.

Front

What gas moves out of the leaf through stomates on a sunny day?

Back

Oxygen moves out of the leaf through stomates.

Front

What is the primary source of mass increase in a tree over time?

Back

The increase in mass comes mostly from carbon dioxide that enters through the leaf openings.

Front

What is photosynthesis?

Back

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

Front

What are the raw materials needed for photosynthesis?

Back

The raw materials needed for photosynthesis are carbon dioxide, water, and light energy.

Front

What is the role of light energy in photosynthesis?

Back

Light energy is converted into chemical bond energy during photosynthesis.
