|---|---|---|---|---|---|
| cytoplasm | All the material, except the nucleus, inside a cell.
🗑
|
||||
| cell membrane | The thin covering that forms the outer boundary of a cell and that is composed primarily of phospholipids and proteins
🗑
|
||||
| selectively permeable membrane | A membrane that only certain molecules can pass through
🗑
|
||||
| passive transport | The movement of substances across a cell membrane without the use of cellular energy
🗑
|
||||
| diffusion | A form of passive transport in which molecules move from an area of higher concentration to an area of lower concentration
🗑
|
||||
| osmosis | The diffusion of water through a selectively permeable membrane
🗑
|
||||
| active transport | The movement of molecules across a cell membrane, requiring the use of cellular energy
🗑
|
||||
| cell wall | A rigid structure manufactured by cells of plants, fungi, algae, and most bacteria to surround the cell membrane
🗑
|
||||
| organelle | One of the cellular structures found in the cytoplasm that perform the functions needed to keep the cell alive
🗑
|
||||
| mitochondria | The organelles in which aerobic respiration occurs to release usable energy from food
🗑
|
||||
| endoplasmic reticulum | An organelle consisting of a network of membranes that enable substances to be transported throughout the cell
🗑
|
||||
| ribosome | A non-membrane-bound organelle that directs the assembling of proteins
🗑
|
||||
| Golgi apparatus | An organelle that collects chemicals from the cytoplasm, processes them, and secretes them
🗑
|
||||
| vacuole | A membrane-bound sac that stores various substances, such as water, food, or wastes, within a cell
🗑
|
||||
| lysosome | An organelle that contains digestive enzymes for disposing of foreign particles and worn-out cellular structures
🗑
|
||||
| chloroplast | An organelle in plants that contains chlorophyll and other pigments; the organelle in which photosynthesis occurs
🗑
|
||||
| cilia | Short, hairlike extensions from a cell membrane that aid in movement
🗑
|
||||
| flagellum | Long, hairlike extensions from a cell membrane that aid in movement
🗑
|
||||
| nucleus | The organelle in eukaryotes that contains chromosomes; the control center of the cell
🗑
|
||||
| eukaryotes | A unicellular or multicellular organism whose cell or cells have a nucleus and other membrane-bound organelles
🗑
|
||||
| prokaryote | A unicellular organism that does not have a membrane around its genetic material and that lacks membrane-bound organelles; an organism in the kingdom Archaebacteria or Eubacteria
🗑
|
||||
| irreducible complexity | The idea that parts of organisms are so complex and dependent on one another that they cannot be reduced to something less complex and still function, providing evidence for Creation
🗑

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.
