Cell Transport

Which is true about active transport?

• It requires energy
• it does not require energy
• It moves substances down the concentration gradient
• it moves material from high to low concentration

This picture represents which type of cellular transport?

• passive transport
• endocytosis
• exocytosis
• osmosis

Large particles of food can be moved into the cell by ________________________.

• endocytosis
• pinocytosis
• exocytosis
• osmosis

The most important part of the cell in cell transport

• E.R.
• cytoplasm
• nucleus 
• cell membrane

What are two types of passive transport?

• endo and exocytosis 
• cookies and milk
• active and passive 
• Osmosis and diffusion

The cell membrane is made mostly of

• phospholipid single layer with proteins
• phospholipid double layer with proteins
• proteins and carbohydrates with ribosomes
• carbohydrates surrounded by golgi bodies

What does it mean that a cell membrane is, "selectively or semi-permeable?"

• It allows all substances in
• It allows some substances in but not others
• It allows nothing in

This is a diagram of...

• exocytosis
• active transport
• osmosis
• equilibrium

Special proteins help move particles, but NO energy is needed. This is..

• facilitated diffusion
• exocytosis
• active transport
• equilibrium

why do cells move things in and out?

• they are bored
• why not
• homeostatis, yo!
