Cellular Transport

Engulfing a large substance from the inside of the cell to move it outside of the cell. 
Uses energy. 

• exocytosis
• endocytosis
• photosynthesis
• diffusion

Particles move from high concentrations to low concentrations.
Doesn't need energy

• passive transport
• facilitated transport
• active transport
• exocytosis

A cell in an isotonic solution will

• swell
• shrink
• stay the same size
• impossible to tell

When a cell is placed in a hypertonic solution water

• moves from the inside of the cell to the solution
• moves from the solution to the inside of the cell
• moves equally in and out of the cell
• none of these

The cell membrane is solid and rigid

• true
• false

What are the channels that aid in facilitated Diffusion made of?

• carbohydrates

• lipids

• nucleic acids

• proteins

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole
• nucleus
• cell membrane
• cell wall

When there are roughly equal numbers of molecules moving in either direction across a semipermeable membrane, and there is no further change in concentration on either side of the membrane, this has been reached.

Which of the following types of cellular transport is demonstrated by the illustration above?

• Active Transport

• Facilitated Diffusion

• Endocytosis

• Diffusion

Water bonds are considered polar bonds because of what characteristics of water molecules?

• the hydrogen and oxygen atoms are ions, meaning they have complete positive and negative charges.

• the oxygen atom is slightly positive, and the hydrogen atoms are slightly negative.

• shared electrons spend more time around the hydrogen atoms than the oxygen atoms.

• the oxygen atom is slightly negative, and the hydrogen atoms are slightly positive.
