Photosynthesis and Cellular Respiration Flash Cards

Front

What do plants give off after photosynthesis?

Back

Oxygen

Answer explanation

After photosynthesis, plants convert carbon dioxide and water into glucose and oxygen. The oxygen produced is released into the atmosphere, making it the correct answer.

Front

Plants need ________from the air for photosynthesis

Back

carbon dioxide

Answer explanation

Plants need carbon dioxide from the air for photosynthesis, as it is a key ingredient in the process of converting light energy into chemical energy. Oxygen, soil, and sugar are not required from the air for this process.

Front

In what part of the cell does photosynthesis occur?

Back

Chloroplast

Answer explanation

Photosynthesis occurs in the chloroplasts, which are specialized organelles in plant cells. They contain chlorophyll, the pigment that captures sunlight, enabling the conversion of light energy into chemical energy.

Front

After photosynthesis, plants store their energy as _________.

Back

glucose (sugar)

Answer explanation

After photosynthesis, plants convert sunlight into chemical energy, storing it primarily as glucose (sugar). This sugar serves as a vital energy source for growth and metabolism.

Front

What is the purpose of photosynthesis?

Back

make glucose

Answer explanation

The purpose of photosynthesis is to make glucose, which plants use as energy. While ATP is produced during the process, the primary goal is glucose synthesis, not making light or releasing carbon dioxide.

Front

What is cellular respiration?

Back

the breakdown of glucose to release ATP

Answer explanation

Cellular respiration is primarily the process of breaking down glucose to release ATP, which is the energy currency of the cell. While carbon is a byproduct, the main goal is to produce ATP for cellular functions.

Front

Where does cellular respiration take place in the cell?

Back

Mitochondria

Answer explanation

Cellular respiration primarily occurs in the mitochondria, often referred to as the powerhouse of the cell. This organelle is responsible for producing ATP, the energy currency of the cell, through the process of respiration.

Front

What is the purpose of cellular respiration?

Back

to release energy from food

Answer explanation

The purpose of cellular respiration is to release energy from food. This process breaks down glucose and other nutrients, converting them into usable energy (ATP) for cellular activities, making the correct answer 'to release energy from food'.

Front

Why is photosynthesis important?

Back

It is the process by which plants make their own food.

Answer explanation

Photosynthesis is crucial because it is the process by which plants make their own food, converting sunlight into energy. This sustains plant life and, in turn, supports the entire ecosystem.

Front

In which way are photosynthesis and cellular respiration different?

Back

Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.

Answer explanation

Photosynthesis uses carbon dioxide to produce glucose and oxygen, while cellular respiration breaks down glucose, releasing carbon dioxide as a byproduct. Thus, the correct choice highlights this key difference.
