Why are fossil fuels considered a nonrenewable resource?

Back

Front

What is exocytosis?

Back

A process where cells expel materials through vesicles that fuse with the cell membrane.

Front

What structures allow oxygen and carbon dioxide to diffuse in and out of a leaf?

Back

Stomata.

Front

How do photosynthesis and cellular respiration differ in terms of gas exchange?

Back

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

Front

What are proteins made of?

Back

Monomers called amino acids.

Front

Define fossil fuels.

Back

Natural substances formed from the remains of ancient organisms, used as energy sources.

Front

What is the role of guard cells in plants?

Back

They regulate the opening and closing of stomata to control gas exchange.

Front

Explain facilitated diffusion.

Back

A process of passive transport that uses proteins to help move molecules across the cell membrane.

Front

What is the primary function of cellular respiration?

Back

To convert glucose into ATP, releasing energy for cellular activities.

Front

What are the products of photosynthesis?

Back

Glucose and oxygen.
