This molecule powers the sodium-potassium pump

ATP

Which of the following is not a type of passive transport?

Endocytosis

which of the following is not a type of passive transport

Endocytosis

A form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane.

Exocytosis

Which type of passive transport uses proteins to help molecules pass through the membrane?

Facilitated diffusion

The cells seem to be swelling and about to burst what type of solution are they most likely in?

Hypotonic

An example of pump transport is

Na+/K+ Pump

Most abundant type of lipid in the cell membrane

Phospholipids

This plant would most likely be

Stiff and rigid

Cell membranes are described as selectively permeable. Four students were asked to explain what this means. Which one is correct?

Student 3: Cell membranes regulate which substances can enter and exit the cell.

What will happen to the cell in the given solution?

Swell up

What would happen to a cell placed in a hypertonic solution

The cell would shrink

What is the force inside the central vacuole called?

Turgor Pressure

In this picture, which way will the water move?

Water will move into the cell

Movement of SOLUTE through the cell membrane from high to low concentration is called.....

diffusion

Nemo and other ocean dwelling fish cannot survive in freshwater because

freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burstfreshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst

What type of solution is this cell in?

isotonic

Moving from areas of LOW concentration to areas of HIGH concentration is called?

Active Transport

Passive Transport

Does NOT require cell energy

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

Equilibrium

In this picture, how do you classify the solution?

The solution is hypotonic

What type of organelle is used during endocytosis and exocytosis?

Vesicle

what type of organelle is used during endocytosis and exocytosis

Vesicle

What is the difference between active and passive transport?

Active uses ATP (energy) and passive does not need energy

white blood cells engulfing invading bacteria is an example of

Endocytosis

Which type of transport gets rid of wastes?

Excoytosis

The cells seem to be shriveled and dehydrated what type of solution are they most likely in?

Hypertonic

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

Into the cell

This plant will most likely be ( look t the right side)

Limp or wilted

Energy from ATP changes the carrier protein's _______ to move molecules in and out of the cell.

Shape

What is diffusion?

The movement of particles from high conc. to low conc. in a given space

What protects carrot cells from swelling too much when it rains?

They have cell walls that keep them from swelling too much.

In plant cells, the force, exerted by the flow of water, within the cell that pushes the plasma membrane against the cell wall. This force gives plants structure and helps them stand up and not wilt.

Turgor Pressure

Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. To move these molecules against their concentration gradient, a ___________ protein is needed.

carrier

Active transport across a cell membrane from low to high concentration, requires

energy (ATP)

What type of solution allows water to enter the plant cell?

hypotonic solution

In an isotonic solution which way will the water flow

it will flow both ways at equal rates

Active transport is the movement of large materials across a cell membrane from ______ to ______ concentration

low to high

The movement of water through a semi-permeable membrane is called

osmosis

What type of transport is this?

endocytosis

What type of solution is this cell in?

hypotonic
