Photosynthesis

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 are the main products of photosynthesis?

Back

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

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, which is essential for photosynthesis.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for the exchange of gases (carbon dioxide and oxygen) between the plant and the environment.

Front

What is the function of xylem in plants?

Back

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

Front

What is the function of phloem in plants?

Back

Phloem is a type of tissue in plants that transports sugars and other metabolic products downward from the leaves.

Front

What is the significance of the waxy covering on evergreen leaves?

Back

The waxy covering on evergreen leaves helps reduce water loss and protects the leaves from harsh environmental conditions.

Front

Why do pine needles have a longer lifespan compared to broadleaf leaves?

Back

Pine needles have a waxy coating and more layers, which help them retain moisture and withstand cold temperatures.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reaction is the first stage of photosynthesis that occurs in the thylakoid membranes, where sunlight is converted into chemical energy (ATP and NADPH) and oxygen is released.

Front

What is the light-independent reaction (Calvin Cycle) in photosynthesis?

Back

The light-independent reaction, also known as the Calvin Cycle, occurs in the stroma of chloroplasts, where ATP and NADPH are used to convert carbon dioxide into glucose.
