|---|---|---|---|---|---|
| Cell | Basic unit of life
🗑
|
||||
| Cell theory | Fundamental concept of biology that states- All living things are composed of cells, cells are the basic unit of structure and function in living things and new cells are produced from existing cells.
🗑
|
||||
| Nucleus | A large membrane-enclosed structure that contains the cells genetic material in form of DNA.
🗑
|
||||
| Eukaryote | Cells that contain nuclei.
🗑
|
||||
| Prokaryote | Cells that do not contain nuclei.
🗑
|
||||
| Organelle | Cells that act as if they are specialized organisms.
🗑
|
||||
| Cytoplasm | The portion of the cell outside the nucleus.
🗑
|
||||
| Nuclear envelope | The cooating around cell that allows material to move in and out of the cell.
🗑
|
||||
| Chromatin | The granular material seen in nucleus. Consist of DNA bound to protein.
🗑
|
||||
| Chromosomes | The granular material seen in a nucleus.
🗑
|
||||
| Nucleolus | The small, dense region in a nuclei.Where ribosomes begins.
🗑
|
||||
| Ribosomes | Small particles of RNA and protein found throughout the cytoplasm. Produces protein by following coded instructions that came from the nucleus.
🗑
|
||||
| Endoplasmic Reticulum | The site where lipid components of the cell membrane are asssembled, along with proteins and other materials that are exported from the cell.
🗑
|
||||
| Golgi Apparatus | The function of the golgi apparatus is to modify, sort, and package proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion outside the cell.
🗑
|
||||
| Lysosomes | Small organelles filled with enzymes.Break down lipids.
🗑
|
||||
| Vacuoles | Sacklike structures that store materials such as water, salts, proteins, and carbs.
🗑
|
||||
| Mitochondria | Organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use.
🗑
|
||||
| Chloroplasts | Organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis.
🗑
|
||||
| Cytoskeleton | Supporting structure that gives eukaryote cells their shape and internal organization.
🗑
|
||||
| Centrioles | Located near the nucleus and organise cell division. Not found in plant cells.
🗑
|
||||
| Cell Membrane | Sometimes called the plasma membrane because many cells in the body are in direct contact with the fluid portion of the blood-the plasma.
🗑
|
||||
| Cell Wall | Strong supporting layer in a cell around the membrane.
🗑
|
||||
| Lipid bilayer | The double layered sheet composition of nearly all cell membranes.
🗑
|
||||
| Concentration | The mass solution in a given volume of sollution, or mass/volume.
🗑
|
||||
| Diffusion | When particles move from a more concentrated area to a less conentrated area.
🗑
|
||||
| Equilibrium | The concentration of a solute is the same througout a system it reaches equilbrium.
🗑
|
||||
| Osmosis | The diffusion of water through a selectively permeable membrane.
🗑
|
||||
| Isotonic | When solutions (water and sugar)will be same on both sides of membrane. Means "same strength"
🗑
|
||||
| Hypertonic | The more concentrated sugar. "more strength"
🗑
|
||||
| Hypotonic |
🗑

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.
