| organelle | a membrane bound structure inside of a cell that has a specific job
🗑
|
||||
| nucleus | a membrane-bound structure in eukaryotic cells, the 'brain' of the cell, controls cellular activity and contains the DNA
🗑
|
||||
| cell wall | A tough, protective barrier that surrounds the outer membrane of some types of cells.
🗑
|
||||
| cell membrane | A lipid barrier that encloses the cytoplasm and controls what enters and exits the cell.
🗑
|
||||
| cytoplasm | the jelly-like substance contained within the cell membrane that fills the cell and holds the organelles in place
🗑
|
||||
| chloroplast | an organelle found only in plant cells, site of photosynthesis
🗑
|
||||
| mitochondrion | the power factory of the cell, source of energy production
🗑
|
||||
| vacuole | A large, water filled organelle present in all plant and fungal cells and some animal and bacterial cells.
🗑
|
||||
| cell theory | first stated by Matthias Schleiden and Theodor Schwann in 1838–39, that cells are the basic units of structure and function in living organisms.
🗑
|
||||
| autotroph | any organism capable of self-nourishment by using photosynthesis as a source of energy, most plants
🗑
|
||||
| heterotroph | capable of utilizing only organic materials as a source of food.
🗑

🗑
|
||||
| lysosome | An organelle that contains enzymes capable of breaking down many types of molecules.
🗑
|
||||
| photosynthesis | A chemical reaction during which plants convert radiant energy from the Sun to chemical energy; the reaction converts carbon dioxide and water into sugar (glucose).
6CO2 + 6O2 ------------> C6H12O6 + 6O2
🗑

||||
| cellular respiration | The process of obtaining energy from the breaking of chemical bonds in nutrients.
Cell Food + O2 ---------> ENERGY + CO2
🗑

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.
