• organelles

• cell wall

• nucleus

What is the difference between active and passive transport?

• Passive transport does not use the cell's energy, Active uses the cells energy.

• Passive transport involves water. Active transport involves proteins.

• Passive transport is for large substances. Active transport is for small substances.

• Active transport moves things from high to low concentration. Passive moves things from low to high concentration.

Substances too large to pass through the cell membrane enter the cell in a process called

• endocytosis

• exocytosis

• passive transport

• active transport

The passive transport of water through a membrane is

• osmosis

• equilibrium

• fermentation

• active transport

What do mitochondria do?

• produce proteins

• contain chlorophyll

• release energy from broken down food molecules

• store food, water and waste materials

How are osmosis and diffusion related?

• osmosis is the active transport of water

• osmosis is the passive transport of water through a membrane by diffusion

• osmosis is the movement of water from low concentration to high concentration

• osmosis is the movement of water without a membrane

Why is water necessary for life?

• Water makes up approximately 75% of a cell's volume

• Water dissolves many substances and carries them across the cell membrane

• Water play an important role in many chemical reactions

• All of these
