|
|
What is the difference between prokaryotic and eukaryotic cells? |
Eukaryotic cells - have a nucleus and membrane bound organelles (larger) Prokaryotic cells - do not have a nucleus or membrane-bound organelles (smaller) |
|
|
Describe how to ID an onion cell at 400 total magnification |
Includes cell wall, cell membrane, and central vacuole Looks like an empty (central vacuole) cell |
|
|

|
|
Describe ways to ID frog skin cells at 400 total magnification |
Includes nucleus and cytoplasm Looks like little purple dots (nucleus), floating in pink (cytoplasm) |
|
|
Found on the outside of the cell and provides a " box" within which the rest of the cell is found |
Cell wall |
|
|
Located inside the cell wall and outside the cytoplasm. Very thin and in plant cells it is pressed up against the cell wall making it difficult to see. |
Plasma membrane, aka cell membrane |
|
|
Appears as a round structure in the center of the cell with small structures seen inside |
Nucleus |
|
|
Appears as a granular material near the cell wall, a very thin layer. |
Cytoplasm |
|
|
A large, water filled space towards the center of the cell. Appears to be empty, due to being full of water. |
Central vacuole |
|
|
Used for movement, attached to the outside of the cell wall. |
Flagella or cilia |
|
|
Elodea leaf |
|
|
Onion cells |
|
|
Frog Skin |
|
|

|
|

No Chloroplasts, no cell wall, multicellular, heterotrophs |
|
|

|
|
ID the components of a solution |
Solutes- dissolved substances Solvents- dissolving agent (substance in which the solute is dissolved) |
|
|
Define diffusion |
Movement of a solute spreading out evenly into the available space |
|
|
Define osmosis |
Passing of a solvent through a semi-permeable membrane |
|
|
Diffusion moves in what direction? |
From where I solute is to wear a solute isn't |
|
|
Osmosis moves in what direction? |
From area of high concentration of solvent to area of low concentration of solvent |
|
Hypertonic or hypotonic? |
Hypertonic |
|
Hypertonic or hypotonic? |
Hypotonic |
|
|
Plant cell that is dehydrated, chloroplasts and central vacuole all shriveled in the middle of the cell. |
Hypertonic |
|
|
Plant cell with excessive water, central vacuole full and chloroplasts pressed against the cell wall |
Hypotonic |
