|---|---|---|---|---|---|
| Prokaryotic | a unicellular organism that lacks a membrane-bound nucleus mitochondria, or any other membrane-bound organelle.
🗑
|

| Eukaryotic | any organism whose cells contain a nucleus and other organelles enclosed within membranes.
🗑
|
||||
| Organelles | any of a number of organized or specialized structures within a living cell.
🗑
|
||||
| Cell Theory | the properties of cells.
🗑
|
||||
| Selectively Permeable | allows certain molecules or ions to pass through it by means of active or passive transport.
🗑
|
||||
| Phospholipid Bilayer | A thin polar membrane made by two membranes of lipids
🗑
|
||||
| Passive Transport | Movement of biomolocules and other atomic substances
🗑
|
||||
| Concentration Gradient | the process of particles (solutes) move through a gas or a solution from an area with a higher number of particles to an area with a lower number of particles.
🗑
|
||||
| Diffusion | a region in which they are in higher concentration to regions of lower concentration.
🗑
|
||||
| Equilibrium | The state in which the concentrations of the diffusing substance in the two compartments are the same or become equal.
🗑
|
||||
| Osmosis | molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one
🗑
|
||||
| Hypotonic | having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid
🗑
|
||||
| Isotonic | denoting or relating to a solution having the same osmotic pressure as some other solution
🗑
|
||||
| Hypertonic | having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid
🗑
|
||||
| Facilitated Diffusion | the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins
🗑
|
||||
| Active Transport | the movement of ions or molecules across a cell membrane into a region of higher concentration
🗑
|
||||
| Membrane Pore | any of numerous structures with complex openings in a nuclear membrane which allow passage of molecules between the nucleus and surrounding cytoplasm
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
