Types of Cell Transport:

Osmosis

Multiple Choice

Passive transport requires no

concentration gradients

osmosis

motion

energy

Multiple Choice

Where is there a low concentration of perfume?

in the bottle

on the hand

in the room

in the top

Multiple Choice

Where is there a high concentration of water?

in the flower

cannot be determined by picture.

in the vase

in the leaves

Multiple Choice

How long does diffusion last?

Until the concentration of particles in the system is equal

Until a region in the system has a smaller concentration of particles than the other

Until a region in the system has a greater concentration of particles than the other

Until the particles disappear from the system

Multiple Choice

Where is there a low concentration of dye?

at the bottom of cup

in the color

at the top of cup

no concenteraion gradient

Multiple Choice

The picture below is an example of _________________.

osmosis

isotonic

diffusion

active transport

Multiple Choice

_______ regulates what enters and leaves a cell.

Cell Membrane

Nucleus

Mitochondria

Cytoplasm

Multiple Choice

Osmosis is the movement of _____ across a membrane.

food

energy

oxygen

water

Multiple Choice

During osmosis

water moves from high to low concentration

large or oddly shaped molecules move across a cell membrane

water moves when energy is used

proteins are built

Multiple Choice

What is the definition of Selective Permeability?

The movement of materials across the cell membrane that requires NO ENERGY from the cell.

The movement of materials through (or across) the cell membrane

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

The movement of molecules from an area of high concentration to a area of low concentration

Multiple Choice

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

Osmosis

Diffusion

Equilibrium

Multiple Choice

Ideally, your cells should be in a(n) _______ solution

Hypertonic

Hypotonic

Isotonic

Cola

Multiple Choice

An animal cell placed in a hypertonic (salty) solution will

Shrink

Swell

Stay the same

Multiple Choice

Why can't you drink salt water?

It's hypertonic to your cells

It's hypotonic to your cells

It's isotonic to your cells

It's paratonic to your cells

Multiple Choice

If the dots represent sugar which is more concentrated

Inside the cell

Outside the cell

Neither they are equal (equilibrium)

Multiple Choice

If the dots represent sugar, what direction will water flow?

Into the cell

Out of the cell

Into and out equally (equilibrium)

Multiple Choice

A person should never drink salty water because their cells would

shrink

expand
