What is a hypothesis?

Back

A statement that can be tested with a valid experiment.

Front

What are the main components of photosynthesis?

Back

Sunlight, water, and carbon dioxide are used to make glucose and oxygen.

Front

How do cellular respiration and photosynthesis relate to carbon dioxide?

Back

Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.

Front

What macromolecule is used for short-term energy storage?

Back

Carbohydrates.

Front

What happens when the concentration of molecules is the same on both sides of a membrane?

Back

The molecules will move across the membrane in both directions.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for the process of photosynthesis.

Front

Define cellular respiration.

Back

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the primary function of lipids in biological systems?

Back

Lipids are used for long-term energy storage and make up cell membranes.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the function of proteins in the body?
