Ch 8 - Cell Transport

Which part of the cell is responsible for moving things in and out of the cell?

• endoplasmic reticulum
• cell membrane
• nucleus
• cilia

Osmosis and diffusion are types of:

• Active transport
• Passive transport
• Potential transport

Diffusion is the movement of molecules from an area of _________ concentration.

• hypotonic to hypertonic
• low to high
• high to low
• outer to inner

What is being shown in the image?

• osmosis
• diffusion
• active transport
• facilitated diffusion

The cell membrane is most similar to a(n):
