|---|---|---|---|---|---|
| active transport | moving material across cell membrane against concentration gradient requiring energy
🗑
|
||||
| passive transport | movement of materials across cell membrane from high to low concentration not requiring energy (diffusion and osmosis)
🗑
|
||||
| hypertonic | solution with a greater concentration of solutes than the cell (in our case)
🗑
|
||||
| hypotonic | solution with lower concentration of solutes than the cell (in our case)
🗑
|
||||
| isotonic | when the concentration of two solution is the same
🗑
|
||||
| cell | basic unit of all living things enclosed in a barrier that separates its inside from its surroundings
🗑
|
||||
| prokaryote | cell with no true nucleus or no other membrane bound organelles, all unicellular
🗑
|
||||
| eukaryote | organized cell with a nucleus and other bound organelles that make up all plants and animals
🗑
|
||||
| organelle | specialized structures that perform important cellular functions in eukaryotic cells
🗑
|
||||
| ATP | adenosiine triphosphate. The energy used in the cell.
🗑
|
||||
| semi-permeable | a membrane that only allows certain molecules to pass through it
🗑
|
||||
| diffusion | the action of molecules moving from an area of high concentration to an area of low concentration
🗑
|
||||
| osmosis | diffusion of water through a semi-permeable membrane
🗑
|
||||
| photosynthesis | carbon dioxide and water get together in sunlight to form glucose and oxygen
🗑
|
||||
| aerobic cellular respiration | glucose and oxygen get together with some energy to form carbon dioxide and water
🗑
|
||||
| chloroplast | site of photosynthesis
🗑
|
||||
| mitochondria | site of cellular respiration
🗑
|
||||
| anaerobic respiration | producing ATP in a cell without any oxygen present
🗑
|
||||
| xylem | this is responsible for taking water from the roots to the rest of the plant
🗑
|
||||
| green | chloroplasts can absorb all light from the visible light spectrum except this col
🗑
|
||||
| carbon dioxide | product of cellular respiration and reactant of photosynthesis, we exhale it
🗑
|
||||
| oxygen | product of photosynthesis and reactant in aerobic respiration, we inhale it
🗑
|
||||
| stomata | tiny openings in leaves that allow carbon dioxide into the plant and oxygen and water out
🗑
|
||||
| chlorophyll | green pigment in chloroplast that traps light energy for photosynthesis
🗑
|
||||
| autotroph | an organism that manufactures its own food
🗑
|
||||
| heterotroph | an organism that is dependent on taking in other organisms for nutrition
🗑
|
||||
| roots | the majority of water taken in by plants enters here
🗑
|
||||
| algae | single cell organism that along with plants does photosynthesis supplying the Earth with oxygen
🗑

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.
