🗑
|
||||
| goligi apparatus | a cell organelle that helps make and package materials to be transported out of the cell
🗑
|

🗑
|
||||
| mitochondrion | in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP

| cell wall | a rigid structure that surrounds the cell membrane and provides support to the cell
🗑
|
||||
| chloroplast | an organelle found in plant and algae cells where photosynthesis occurs
🗑
|
||||
| cell membrane | a phospholipid layer that covers a cell’s surface and acts as a barrier between the inside of a cell and the cell’s environment
🗑
|
||||
| phospholipid | a lipid that contains phosphorus and that is a structural component in cell membranes
🗑
|

🗑
|
||||
| diffusion | the movement of particles from regions of higher density to regions of lower density
🗑
|
||||
| concentration gradient | a difference in the concentration of a substance across a distance
🗑
|
||||
| osmosis | the diffusion of water or another solvent from a more dilute solution (of a solute) to a more concentrated solution (of the solute) through a membrane that is permeable to the solvent
🗑
|
||||
| isotonic |
🗑
|
||||
| hypertonic | describes a solution whose solute concentration is higher than the solute concentration inside a cell
🗑
|
||||
| hypotonic | describes a solution whose solute concentration is lower than the solute concentration inside a cell
🗑
|
||||
| facilitated diffusion | the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins
🗑
|
||||
| active transport | the movement of chemical substances, usually across the cell membrane, against a concentration gradient; requires cells to use energy
🗑
|
||||
| endocytosis | the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
🗑
|
||||
| phagocytosis | the process by which a cell engulfs large particles or whole cells, either as a defense mechanism or as a means to obtain food
🗑
|
||||
| excocytosis | the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out
🗑

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.
