| cell wall | show 🗑
|
||||
| show | fundamental structural component of biological membranes, consisting of two layers of lipids (primarily phospholipids) and proteins
🗑
|
||||
| show | a membrane (like a cell membrane) that allows certain substances to pass through while restricting others
🗑
|
||||
| show | describes the structure of cell membranes as a flexible, dynamic mosaic of phospholipids, proteins, cholesterol, and carbohydrates
🗑
|
||||
| passive transport | show 🗑
|
||||
| show | the passive movement of molecules or particles from an area of high concentration to an area of low concentration across a semipermeable membrane; example is gasses pass through
🗑
|
||||
| facilitated diffusion | show 🗑
|
||||
| show | specialized membrane proteins that function as water channels, facilitating the movement of water across cell membranes
🗑
|
||||
| osmosis | show 🗑
|
||||
| show | the ability of a solution to affect the volume of a cell by causing osmosis, the movement of water across a semipermeable membrane.
🗑
|
||||
| show | one where the concentration of solutes (dissolved substances) is equal to the concentration of solutes inside a cell. This
🗑
|
||||
| show | a solution that has a lower concentration of solutes than the cell it is compared to
🗑
|
||||
| show | a solution that has a higher concentration of solutes (and thus a lower concentration of water) compared to another solution or a cell
🗑
|
||||
| osmotic pressure | show 🗑
|
||||
| turgid | show 🗑
|
||||
| show | a plant cell or tissue that is soft, limp, and lacks turgor pressure. T
🗑
|
||||
| show | the process of a cell breaking down and dissolving, typically due to damage to its membrane or cell wall
🗑
|
||||
| active transport | show 🗑
|
||||
| show | a protein embedded in a cell membrane that uses energy to move molecules, like ions or other solutes, across the membrane against their concentration gradient
🗑
|
||||
| bulk transport | show 🗑
|
||||
| show | an active transport process where a cell's membrane engulfs external substances, forming vesicles or vacuoles that bring materials into the cell
🗑
|
||||
| exocytosis | show 🗑
|
||||
| show | the body's ability to maintain a stable internal environment despite external changes.
🗑
|
||||
| show | a specialized molecule, often a protein, that binds to a specific signaling molecule called a ligand and initiates a response within the cell
🗑
|
||||
| show | a eukaryotic cell that is a building block of all animal organisms.
🗑
|
||||
| show | a eukaryotic cell that makes up the building blocks of all plants.
🗑
|
||||
| show | the physical dimensions of a cell, typically measured in micrometers (μm) or nanometers (nm)
🗑
|
||||
| show | the total area of the outer boundary of an organism, cell, or structure, over which substances and heat can be exchanged with the environment. Relates to cell membrane
🗑
|
||||
| show | the three-dimensional space occupied by a cell. Relates to the cytoplasm.
🗑
|
||||
| surface area to volume ratio | show 🗑
|
||||
| show | The process by which cells reproduce.
🗑
|
||||

🗑
|
||||
| mitosis | show 🗑
|
||||

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.
