What is the overall goal of ALL cellular transport?

• to make a gradient

• to maintain homeostasis

• to make the cells shrink

• to keep molecules where they are

What characteristic does the cell membrane have that describes it's ability to let some things in and keep other things out of the cell?

• selectively permeable

• impermeable

• controlling

• fluid

When water moves across the cell membrane, is energy used?

• Yes, it is active transport

• Yes, it is passive transport

• No, it is active transport

• No, it is passive transport

Which type of transport does NOT use vesicles and energy?

• Facilitated Diffusion

• Endocytosis

• Exocytosis

The difference between passive and active transport is that active transport

• uses energy

• does not use energy

• goes from HIGH to LOW

• moves molecules randomly

Does facilitated diffusion require energy?

• Yes

• No

Does endocytosis require energy?

• Yes

• No

Does osmosis require energy?

• Yes

• No

Which type of transport moves molecules from an area of HIGH concentration to an area of LOW concentration?

• Active

• Passive

What type of transport is this?

• Osmosis

• Endocytosis

• Exocytosis

• Protein Pump
