Photosynthesis, plants, and CR FLASHCARD

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 role do stomata play in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they enable carbon dioxide to enter the leaf for photosynthesis and oxygen to exit.

Front

What is the function of guard cells?

Back

Guard cells surround each stoma and control its opening and closing in response to environmental conditions, regulating gas exchange and water loss.

Front

What is ATP and its role in living organisms?

Back

ATP (adenosine triphosphate) is a molecule that carries energy within cells, used for various cellular processes including muscle contraction, nerve impulse propagation, and biosynthesis.

Front

What is the function of xylem in plants?

Back

Xylem is a type of vascular tissue in plants that conducts water and dissolved minerals upward from the roots to the rest of the plant.

Front

What is the function of phloem in plants?

Back

Phloem is a type of vascular tissue that transports sugars and other metabolic products downward from the leaves to other parts of the plant.

Front

Where are plant cells specialized for cell division found?

Back

Plant cells specialized for cell division are primarily found in the root tips and shoot tips, known as meristems.

Front

What is transpiration in plants?

Back

Transpiration is the process by which water vapor is released from the interior of a plant to the atmosphere through stomata, helping to regulate temperature and nutrient transport.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.
