|---|---|---|---|---|---|
| Active Transport | the cell uses energy to move molecules against the flow of diffusion (low to high concentration)
🗑
|
||||
| Cell | basic unit of structure and function in living things
🗑
|
||||
| Cell Membrane | thin flexible barrier around the cell; selectively permeable
🗑
|
||||
| Cell Wall | rigid layer around the cell membrane; provides support and protection for the cell; only found in plant cells
🗑
|
||||
| Chloroplast | uses energy from sunlight to make food molecules
🗑
|
||||
| Chromatin | granular material visible within the nucleus
🗑
|
||||
| Cytoplasm | watery material around organelles; most reactions occur here
🗑
|
||||
| Cytoskeleton | maintains cell shape with a network of protein filaments
🗑
|
||||
| Diffusion | process by which molecules of a substance move form areas of high concentration to low concentration; does not require energy; molecules spread evenly (Hint: open a perfume bottle and the smell will eventually fill room)
🗑
|
||||
| Endoplasmic Reticulum | assembles components of the cell membrane and modifies some proteins
🗑
|
||||
| Eukaryote | organism whose cells contain a nucleus (Hint: you)
🗑
|
||||
| Golgi Bodies (Golgi Apparatus) | attaches carbohydrates and lipids to proteins using enzymes
🗑
|
||||
| Mitochondria | uses energy from food to make high energy compounds; the cell's powerhouse; cell's respiration
🗑
|
||||
| Nucleus | controls most cell processes and contains DNA; brain of cell
🗑
|
||||
| Organelle | specialized structures within a cell that perform important cell functions
🗑
|
||||
| Osmosis | diffusion of water through a selectively permeable membrane; must have membrane (Hint: cell placed in fresh water will absorb water until it becomes swollen and may burst; cell placed in salt water will shrink - Salt Sucks!)
🗑
|
||||
| Phagocytosis | process by which extensions of cytoplasm engulf large particles
🗑
|
||||
| Receptor Molecules | receive appropriate cells and trigger some sort of response by the cell (fit together like a puzzle piece)
🗑
|
||||
| Ribosome | make protein (Hint: ribs have some - meat ribs are protein)
🗑
|
||||
| Vacuole | sac life structures for storage of water, salts, proteins, and carbohydrates
🗑

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.
