|---|---|---|---|---|---|
| What are some cell functions? | covering, lining, storage, movement, connection, defense, communication, reproduction.
🗑
|
||||
| Plasma membrane | forms the outer, limiting barrier separating the internal contents of the cell from external materials.
🗑
|
||||
| cytoplasm | general term for all cellular contents between the plasma membrane and the nucleus. Made of cytosol, organelles, and inclusions
🗑
|
||||
| nucleus | the control center of the cell.
🗑
|
||||
| plasma membrane | cell membrane that forms the thin outer border of the cell
🗑
|
||||
| plasmalemma | the plasma membrane is a flexible layer that separates the internal components of a cell from the external environment and extracellular materials
🗑
|
||||
| extracellular fluid | interstitial fluid in the external environment of the cell
🗑
|
||||
| lipids | fats, oils, and steroids that are insoluble in water. the three types in the plasma membrane are phospholipids, cholesterol, and gylcolipids.
🗑
|
||||
| phospholipids | contain both water-soluble and water-insoluble regions as well as the element phosphate. phospholipids are most of the plasma membrane lipids
🗑
|
||||
| cholesterol | a steroid found in 20% of the membrane lipids. scattered in hydrophobic regions of the phospholipid bilayer, where it strengthens the membrane and stabilizes it at temperature extremes
🗑
|
||||
| What are some general functions of the plasma membrane? | communication, intercellular connection, physical barrier, selective permeability.
🗑
|
||||
| What are some protein-specific functions of the plasma membrane? | transport, intercellular attachment, anchorage for the cytoskeleton, enzyme (catalytic) activity, cell-cell recognition, signal transduction.
🗑
|
||||
| What are some factors that influence membrane permeability of transport across the plasma membrane? | transport proteins, plasma membrane structure, concentration gradient, ionic charge, lipid solubility, molecular size
🗑

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.
