Term
| List the three parts of cell theory. |
|
Definition
1. All living things are made of cells
2. Cells can only come from other living things
3. The cell is the basic structure and function of the living things. |
|
|
Term
| Who was the scientist who discovered and named the cell? |
|
Definition
|
|
Term
| Identify and organize the levels of organization of multi-cellular organisms. |
|
Definition
| cells -> tissues -> organs -> systems |
|
|
Term
| Identify the distinguishing a characteristics of a prokaryotic cell, eukaryotic cell, and a virus. |
|
Definition
Prokaryotic: Cells without a nucleus or other membrane bound organelles.
Eukaryotic: Have a nucleus and other organelles bound by membranes.
Viruses: non-living strand of genetics that can not replicate on its own, nucleic acid core, protein coat, and can include cells, alter cellular function. |
|
|
Term
| What is the difference between a plant cell and an animal cell? |
|
Definition
| A plant cell has a cell wall and chloroplast and an animal cell does not. |
|
|
Term
| How are viruses and bacteria different? |
|
Definition
Viruses: non-living strand of genetics that can be harmful
Bacteria: Prokaryotes, some are helpful to humans and the environment, small amounts are diseases. |
|
|
Term
|
Definition
| When particles travel from a higher concentrated area to a lower concentrated area. |
|
|
Term
|
Definition
| When water moves across a selectively permeable membrane. |
|
|
Term
| What is active transport? |
|
Definition
| Diffusion going against the concentration gradient requiring energy. |
|
|
Term
|
Definition
| Energy needed for cells to release waste, substances of the plasma membrane. |
|
|
Term
|
Definition
| Energy needed for large substances to enter the cell. |
|
|
Term
| What is facilitated diffusion? |
|
Definition
| passive transport of ions and small particles across the plasma membrane that transport protein. |
|
|
Term
| Compare and contrast how molecules move across the membrane freely or with the use of energy. |
|
Definition
passive transport: no energy is needed for the molecules to move in and out.
active transport: requires the cell to use energy/ substances move against the concentration gradient. |
|
|
Term
| Describe the effects of an isotonic, hypertonic, and hypotonic solution in a cell. |
|
Definition
Isotonic:concentration of the solute is same in and out.
Hypertonic: there is more solute outside the cell.
Hypotonic: there is less solute outside the cell. |
