AQA Bioenergetics Revision Flashcard

Front

What is the Waxy Cuticle and its function in a leaf?

Back

The Waxy Cuticle is a protective layer on the upper epidermis of a leaf that reduces water loss by preventing evaporation.

Front

What organelle is responsible for photosynthesis?

Back

Chloroplast is the organelle primarily involved in the process of photosynthesis, converting light energy into chemical energy.

Front

What is a common feature of both photosynthesis and respiration?

Back

Both photosynthesis and respiration involve the exchange of gases, specifically oxygen and carbon dioxide.

Front

Where does photosynthesis mainly occur in a plant?

Back

Photosynthesis mainly occurs in the leaves of a plant, where chloroplasts are abundant.

Front

What is one of the reactants of cellular respiration?

Back

Glucose is one of the reactants of cellular respiration, which is used to produce energy.

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 is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy, while anaerobic respiration occurs without oxygen and produces less energy.
