Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy by the cell. It occurs along the concentration gradient.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until they are evenly distributed.

Front

What role do people (and other organisms) perform in the carbon cycle?

Back

People and other organisms perform cellular respiration, which releases carbon dioxide into the atmosphere.

Front

What role do plants (producers) perform in the carbon cycle?

Back

Plants take in carbon dioxide from the atmosphere and release oxygen through the process of photosynthesis.

Front

What is the function of the central vacuole in plant cells?

Back

The central vacuole stores water and helps maintain turgor pressure, providing rigidity to the plant cell.

Front

What are the six kingdoms of life?

Back

The six kingdoms of life are Archaea, Bacteria, Protists, Animals, Plants, and Fungi.

Front

How are fossil fuels formed?

Back

Fossil fuels are formed from the remains of plants and animals that have been buried underground for millions of years, undergoing heat and pressure.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is cellular respiration?

Back

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