|---|---|---|---|---|---|
| cell | basic unit of all life
🗑
|
||||
| organelle | specialized structures that perform important cellular functions
🗑
|
||||
| What is the difference between a eukaryotic and prokaryptic cell? | prokaryotic cells do not have a nucleus and eukaryotic cells do have a nucleus.
🗑
|
||||
| What makes up the phosopholipid bilayer of a cell membrane? | a phosphate head (water loving and a fatty acid tail (water fearing)
🗑
|
||||
| concentration | The amount of salute in a solution. salute +solvent= salution
🗑
|
||||
| diffusion | Moves small molecules into and out of the cell, moves from an area of high to an area of low concentration, does not use energy
🗑
|
||||
| facillitated diffusion | Moves small molecules into and out of the cell, move from an area of high to and area of low concentration, uses protein channels, no energy
🗑
|
||||
| osmosis | Moves small water only molecules into and out of the cell membrane by way of aquaporins, moves from an area of high to low concentration, no energy required
🗑
|
||||
| isotonic | The concentration of two solutions are the same , equal
🗑
|
||||
| hypertonic | The solution with the greater concentration of solutes, the cell shrinks
🗑
|
||||
| hypotonic | the solution with the lesser concentration of salutes, the cell swells
🗑
|
||||
| Active transport | Movement across the cell membrane, moves from low to high concentration, requires energy.
🗑
|
||||
| molecular transport | movement across the cell membrane using protein pumps, moves large molecules from low to high concentration, requires energy
🗑
|
||||
| endocytosis | movement of large molecules into the cell by engulfing the molecule, surrounding it with a vessicle and pulling it into the cell.
🗑
|
||||
| exocytosis | the releasing of a large molecule by the cell into it's surrounding environment.
🗑
|
||||
| photosynthesis | CO2 (carbon dioxide) +H2O (water) react to make the products C6H12O6 (glucose) + O2 (oxygen)
🗑
|
||||
| pigment | Is a light absorbing molecule
🗑
|
||||
| Chlorophyll | Pigment within plants and other photosynthetic organisms
🗑
|
||||
| What are the two main functions of the cell membrane? | 1. controls what enters and leaves the cell maintaining homeostasis. 2. provides protection and support for the cell.
🗑
|
||||
| What are the three types of passive transport? | 1. diffusion 2. osmosis 3. facillitated diffusion
🗑
|
||||
| What are the three types of active transport? | 1. molecular transport 2. endocytosis 3. exocytosis
🗑
|
||||
| What direction will water diffuse based on the concentrations of two solutions? | Water will diffuse to dilute the solute , water will move into the area with the highest concentration of salute.
🗑
|
||||
| What are the two forms of endocytosis? | 1. phagocytosis-cell eating
2. pinocytosis-cell drinking
🗑
|
||||
| What are the three parts of an ATP molecule? | 1. base-adenine
2. phosphates (3)
3. Bonds - energy is stored between the 2nd and 3rd bonds
🗑
|
||||
| What are the three factors that affect photosynthesis? |
🗑

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.
