Carbon Cycle Flashcards

Front

Calvin Cycle

Back

A process in plants that happens during photosynthesis. It uses carbon dioxide, energy from sunlight and water to make glucose, a type of sugar that plants use for energy and growth.

Front

ATP (Adenosine Triphosphate)

Back

A molecule that acts like a tiny battery for cells. It stores and provides energy.

Front

Cellular Respiration

Back

The process cells use to turn food into energy. It’s how your body gets energy to work, grow, and stay alive.

Front

Nitrogen Fixation

Back

The process of turning nitrogen gas from the air into a form that plants can use, like ammonia.

Front

Nitrification

Back

The process where bacteria in the soil change ammonia into nitrates and nitrites, which are nutrients that plants can absorb and use to grow.

Front

Ammonification

Back

The process where bacteria and fungi break down dead plants, animals, and waste into ammonia, a form of nitrogen. This helps return nitrogen to the soil so plants can use it to grow.

Front

Assimilation

Back

When living things take in nutrients and use them to grow and build their bodies. For example, plants absorb nutrients from the soil, and animals use the nutrients from the food they eat to make energy and build cells.

Front

Phloem Cells

Back

Special tubes in plants that carry food, like sugar, from the leaves (where it’s made during photosynthesis) to the rest of the plant. They act like a delivery system, sending energy to parts of the plant that need it.

Front

Palisade Cells

Back

Plant cells found in leaves. They are packed with chloroplasts, which help the plant make food through photosynthesis.
