List the two types of cells.

Eukaryotic & Prokaryotic

100

The uneven distribution of electrons makes water

Polar

100

Transport that requires no energy and materials move from an area of high concentration to low concentration

Passive Transport

100

Active transport where small pockets of liquid are taken into the cell

Pinocytosis

100

Purpose of the cell membrane

Regulates what enters and leaves the cell

200

Identify the prokaryotic and eukaryotic cell

A= prokaryotic B= eukaryotic

200

A solution that resists a change in pH when strong acids or bases are added

Buffer

200

Three types of passive transport

Diffusion, Osmosis, Facilitated diffusion

200

Active transport where the cell bringing a molecule (particle) INTO the cytoplasm

Endocytosis

200

The phosphate head

Hydrophilic/polar

300

What is the cell theory?

1. all cells come from pre-existing cells 2. cells are the basic unit of structure and function of living things 3. all living things are made up of one or more cells

300

When pH is high, Hydrogen ion concentration is

Low

300

When a normal cell is placed in a hypertonic solution it

There is a net movement of water out of the cell and will shrink due to osmotic pressure.

300

The two types of endocytosis

Phagocytosis (large solid molecules) and pinocytosis (molecules dissolved in liquid)

300

Material that channels and pumps are made of 

Proteins

400

If viewing a cell under a microscope, how would you be able to identify the cell as either a plant or animal cell.
Plant- square, cell wall, LARGE central vacuole and chloroplast animal cell- round, small vacuoles (if any)

400

The characteristic of water molecules sticking to other surfaces

Adhesion

400

In a hypotonic solution

Water enters cell, it swells and internal pressure increases. Animal cells may break (lyse), plant cells are supported by cell walls and will not break



400

Exocytosis.

Vesicles are filled with molecules in the inside of the cell and then fuse with the plasma membrane and deposit the molecules outside the cell.

400

An animal cell with an internal concentration of 1.0% is placed in a solution with a salt concentration of 0.3%

The cell will swell and burst due to the solution being hypertonic with respect to the cell, causing a movement of water into the cell

500

Describe what is happening to the cells in the image below. Be sure to mention all organelles and concentrations involved.

cell was placed in a hypertonic solution and water is diffusing out of the cell through the process of osmosis.

500

The concentration of H+ in solution, or the measure of how acidic or basic a solution is

pH

500

Type of passive transport would be used to move the following molecules across the cell membrane: glucose, small molecules in solution, and water

glucose-facilitated diffusion, small molecules in solution-diffusion, water-osmosis

500

What type of transport is represented and why?
Active transport: energy is being used and molecules are moving from low to high concentration.

500

Keeps membrane “fluid” by preventing fatty acid tails from sticking together
