|
|
||||
|---|---|---|---|---|---|
| cell | the smallest living unit of any organism
🗑
|
||||
| nucleus | a large membrane-enclosed structure that contains the cell's activities
🗑
|
||||
| eukaryotes | cells that enclose their DNA in nuclei
🗑
|
||||
| prokaryotes | cells that do not enclose DNA in nuclei
🗑
|
||||
| cytoplasm | the gel portion of the cell outside the nucleus
🗑
|
||||
| organelles | cellular structures that act as if they are specialized organs. Literally translated as "little organs"
🗑
|
||||
| vacuoles | store materials like water, salts, proteins, and carbohydrates
🗑
|
||||
| lysosomes | break down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell
🗑
|
||||
| cytoskeleton | helps the cell maintain its shape and is also involved in movement
🗑
|
||||
| microfilaments | threadlike structures made up of a protein called actin. They form extensive networks in some cells and produce a tough, flexible framework that supports the cell
🗑
|
||||
| microtubules | hollow structures made up of proteins known as tubulins. They play critical roles in maintaining cell shape.
🗑
|
||||
| centrioles | located near the nucleus and help to organize cell division. They are not found in plant cells.
🗑
|
||||
| ribosomes | small particles of RNA and protein found throughout the cytoplasm in all cells. They produce proteins by following coded instructions that come from DNA.
🗑
|
||||
| golgi apparatus | modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for the storage in the cell or release outside the cell.
🗑
|
||||
| endoplasmic reticulum | where lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell
🗑
|
||||
| chloroplasts | capture the energy from the sunlight and convert it into compounds that are more convenient for the cells to use
🗑
|
||||
| cell membrane | regulates what enters and leaves the cell and also protects and supports the cell
🗑
|
||||
| mitochondria | convert the chemical energy stored in food into compounds that are more convenient for the cells to use
🗑
|
||||
| cell walls | lie outside the cell membrane and most are porous enough to allow water, oxygen, carbon dioxide, and certain other substances to pass through easily. Their main function is to provide support and protection for the cell.
🗑
|
||||
| lipid bilayer | a double-layered sheet which gives cell membranes a flexible structure and forms a strong barrier between the cell and its surrondings
🗑

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.
