Chapter 4: Cells and Energy Review

What are the basic building blocks of life?

• cell membrane

• cells

• molecules

All activities require what?

• energy or ATP

• food

• cells

Where does energy for a cell come from?

• light

• sugar molecules (food)

• All of the above

What are the two forms of energy?

• light energy and chemical energy

• sun energy and food energy

• Energy drinks

What form of energy is found in food?

• light energy

• solid energy

• chemical energy

Having tiny holes or pores that allow molecules to diffuse into the cell.

• cell membrane

• semipermeable

• equilibrium

Molecules moving from a crowded area to a less crowded area. (Same as passive transport- it does NOT use energy)

• endocytosis

• osmosis

• diffusion

The diffusion of water through the cell membrane.

• osmosis

• exocytosis

• equilibrium

A plant that receives water....

• vacuoles are small and droops

• vacuoles swell and may stand up straight

The diffusion of molecules through a cell membrane, WITHOUT help or energy. (no energy- moves with the crowd)

• active transport

• mitochondria

• passive transport
