🗑
|
||||

🗑
|
||||
| what is a microtubules | in cytoplasm. supports cytoplasm. assists in cell division and forms components of cilia and flagella.
🗑
|

| what is a cilia | on cell surface with many on each cell. cilia move substances over surface of certain cells
🗑
|
||||

🗑
|
||||
| what is a microvilli | extensions of cell surface with many on each cell. increase surface area of certain cells.
🗑
|
||||
| what is a ribosomes | organelles where proteins are produced
🗑
|
||||
| what is a cytoskeleton | consists of proteins that support the cell, hold organelles in place and enable the cell ot change shape.
🗑
|
||||
| what are four ways molecules can pass through the cell membrane | 1. moves through phospholipids membrane
2. carrier molecules brings things in/out
3. through the membrane channels
4. through vesicles
🗑

🗑
|
||||
| what is a solvent | the substance that does the dissolving
🗑
|
||||
| what is diffusion | movement of molecules from an area of higher concentration to an area of lower concentration
🗑
|
||||
| what is the concentration gradient | measure of the difference in the concentration of solute in a solvent
🗑
|

🗑
|
||||
| what is osmotic pressure |
🗑
|
||||
| what is hypotonic | low solute concentration inside of a cell
🗑
|
||||
| what is isotonic | concentration of solutes is equal both inside and outside of the cell
🗑
|
||||
| what is hypertonic | high solute concentration inside of the cell
🗑
|
||||
| what is faciliated diffusion | larger molecules use carrier protein to help them pass through the cell membrane
🗑

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.
