Photosynthesis part 1 review

Front

What is the function of phloem in plants?

Back

Phloem is the plant tissue that carries food materials downward from the leaves to the rest of the plant.

Front

Where do the light reactions of photosynthesis occur?

Back

The light reactions occur in the thylakoid membrane of the chloroplasts.

Front

What occurs when stomata are open in a leaf?

Back

When stomata are open, carbon dioxide enters the leaf.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which hydrogen ions move through ATP Synthase, allowing them to pass through a membrane with the help of a transport protein.

Front

What is the role of xylem in plants?

Back

Xylem is the vascular tissue that transports water and minerals upwards from a plant's roots.

Front

Define 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 are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the primary pigment involved in photosynthesis?

Back

The primary pigment involved in photosynthesis is chlorophyll, which absorbs light energy.

Front

Explain the significance of stomata in photosynthesis.

Back

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

Front

What is the role of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) serves as the energy currency of the cell, providing energy for various biochemical reactions during photosynthesis.
