|---|---|---|---|---|---|
| Diffusion | passive transport where a solute travels from an area of higher concentration to an area of lesser concentration with the gradient.
🗑
|
||||
| Osmosis | passive transport where water (solvent) travels thru a selectively permeable membrane when a concentration gradient is present.
🗑
|
||||
| Facilitated Diffusion | Carrier-mediated passive transport is a variation of diffusion in which a carrier molecule helps a substance move across the membrane
🗑
|
||||
| Filtration | pressure is applied to force water and its dissolved materials across a membrane.
🗑
|
||||
| Active Transport (3 types) | 1. Active Transport Pumps
2. Endocytosis
3. Exocytosis
🗑
|
||||
| Pinocytosis | liquid brining liquid is brought inside the cell using ATP.
🗑
|
||||
| Active Transport Pumps | require ATP energy to move substances against the concentration gradient
🗑
|
||||
| Cell Membrane | surrounds the cytoplasm and provides a protective covering.
🗑
|

🗑
|
||||
| Mitosis, Malignant Tumors | grow rapidly and invade, health cell tissue.
🗑
|
||||
| Mitosis, Metastasis | parts break off and travel thru the blood or lymph system and start tumors in other parts of the body.
🗑
|
||||

| ATP | adenosine triphosphate
🗑
|
||||
| Cytokinesis | division of the cytoplasm and organelles.
🗑

||||
| Bacteria | simple one-celled organisms without a nucleus or many organelles

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.
