Question

compare/contrast the kinds of transport
is the following solution hypertonic, hypotonic, or isotonic?
where is there more water? in the solution or inside the cell?
which way does the water diffuse?
what will happen to the cell?
if the solute molecules can move, which way would they move?
diffusion
facilitated diffusion
osmosis
protein pumps
endocytosis (phagocytosis)
endocytosis (pinocytosis)
exocytosis
active or passive
does it need energy?
do the molecules move down or against the concentration gradient?

Explanation:

Diffusion is passive transport where molecules move down the concentration gradient without energy. Facilitated diffusion is also passive, using transport proteins to move molecules down the gradient. Osmosis is the passive movement of water across a semi - permeable membrane. Protein pumps are active transport, using energy to move molecules against the concentration gradient. Endocytosis (phagocytosis and pinocytosis) is active, engulfing substances into the cell, and exocytosis is active, releasing substances out of the cell. For hypertonic solutions, water moves out of the cell; for hypotonic, water moves in; and for isotonic, there is no net water movement.

Answer:

Transport Type	Active or Passive	Does it need energy?	Do the molecules move down or against the concentration gradient?	Is solution hypertonic, hypotonic, or isotonic (general concept)	Where is more water (general concept)	Which way does water diffuse (general concept)	What will happen to the cell (general concept)	If solute molecules can move, which way would they move (general concept)
Facilitated Diffusion	Passive	No	Down	N/A	N/A	N/A	N/A	Down the gradient
Osmosis	Passive	No	N/A (water movement)	Hypertonic: outside has more solute; Hypotonic: inside has more solute; Isotonic: equal solute	Hypertonic: inside cell; Hypotonic: outside cell; Isotonic: equal	Hypertonic: out of cell; Hypotonic: into cell; Isotonic: no net movement	Hypertonic: cell shrinks; Hypotonic: cell swells; Isotonic: stays the same	N/A
Protein Pumps	Active	Yes	Against	N/A	N/A	N/A	N/A	Against the gradient
Endocytosis (phagocytosis)	Active	Yes	N/A	N/A	N/A	N/A	N/A	N/A
Endocytosis (pinocytosis)	Active	Yes	N/A	N/A	N/A	N/A	N/A	N/A
Exocytosis	Active	Yes	N/A	N/A	N/A	N/A	N/A	N/A
