When you sit in the bathtub, your fingers get wrinkly because of the water entering your skin cells. The bathtub water is a ____________ solution compared to your skin cells

hypotonic

Hypotonic isotonic hypertonic

This type of transport is called

_______________endocytosis

Diffusion continues

until the concentration of molecules is equal throughout the space.

This is called ___________________equilibrium

____________ transport can move molecules AGAINST the concentration gradient.

Active Passive

ACTIVE

Name a kind of transport that uses vesicles to move substances acrossa membrane

Exocytosis, endocytosis

Name the kind of transport thatmoves WATER across cell membranes

OSMOSIS (Facilitated diffusion with aquaporins)

A freshwater fish has about 1% salt in his body. Freshwater is close to 0% salt.

Will water move into or out of this kind of fish?

More solute molecules insidethe fish’s cells than in the freshwater.(HYPOTONIC)Water will moveINTO the fish

The white circles stand for oxygen molecules.

Use what you know about diffusion of molecules to predict which way the oxygen will move.

From the lungs into the blood(Move from a High concentration to low concentration)

The shrinking away of the cell membrane from the cell wall in a plant cell when placed in a HYPERTONIC environment

plasmolysis

An INTEGRAL MEMBRANE PROTEIN that moves molecules PASSIVELY across cell membranes by attaching, CHANGING SHAPE, and flipping to the other side like a revolving door

carrier protein

______________exocytosis

The energy for active transportcomes from this molecule

HYPERTONIC HYPOTONICISOTONIC

Healthy cells work to “maintain stable internal conditions” also called ____________. If this doesn’t happen, cells can be damaged.

(That is what happens when cells shrink or swell in hypotonic or hypertonic solutions.)

homeostasis

HOW are pumps different from facilitated diffusion carriers and channels?

Pumps require energy (active transport)and carriers and channels don’t needenergy (passive transport)

Pumps move against the gradient (low →high)Carriers/channels move with the gradient (high → low)
