List the two types of cells.
Eukaryotic & Prokaryotic
The uneven distribution of electrons makes water
Transport that requires no energy and materials move from an area of high concentration to low concentration
Active transport where small pockets of liquid are taken into the cell
Purpose of the cell membrane
Regulates what enters and leaves the cell
Identify the prokaryotic and eukaryotic cell
A= prokaryotic B= eukaryotic
A solution that resists a change in pH when strong acids or bases are added
Three types of passive transport
Diffusion, Osmosis, Facilitated diffusion
Active transport where the cell bringing a molecule (particle) INTO the cytoplasm
The phosphate head
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
When pH is high, Hydrogen ion concentration is
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.
The two types of endocytosis
Phagocytosis (large solid molecules) and pinocytosis (molecules dissolved in liquid)
Material that channels and pumps are made of
The characteristic of water molecules sticking to other surfaces
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
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.
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
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.
The concentration of H+ in solution, or the measure of how acidic or basic a solution is
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
Keeps membrane “fluid” by preventing fatty acid tails from sticking together
