|---|---|---|---|---|---|
| Cell | smallest unit that can perform all the life processes
🗑
|
||||
| cell specialization | ability of different cells to perform specific functions in a multicellular organism, such as protection, mobility and reproduction.
🗑
|
||||
| cell wall | Provides structure for the cell. Only found in plant cells.
🗑
|
||||
| Chemical Signals | hormones and neurotransmitters that send "messages" from one cell to another
🗑
|
||||
| Cytoplasm | Fluid material inside the cell. Contains the structures of the cell.
🗑
|
||||
| Eukaryote | complex cell that has nucleus and membrane bound organelles.
🗑
|
||||
| Hormones | substance released by glands to produce change from within.
🗑
|
||||
| Nucleus | organelle that houses the DNA of eukaryotic cells
🗑
|
||||
| Organelle | subcellular structure that has a special function.
🗑
|
||||
| plasma membrane | thin layer on the surface of all cells, consisting mainly of lipids and proteins.
🗑
|
||||
| Prokaryote | a cell without a nucleus
🗑
|
||||
| Ribosome | organelle on which proteins are synthesized.
🗑
|
||||
| Semi-permeable | allows passage of only certain types of molecules
🗑
|
||||
| Cilia | hair like organelles that line the surfaces of some cells that beat in rhythmic waves, providing locomotion
🗑
|
||||
| contractile vacuole | found in many microorganisms that expand, filled with water and then empties contents to the exterior.
🗑
|
||||
| Flagella | Whip-like tail that enables some organisms to move.
🗑
|
||||
| stem cells | can divide (through mitosis) and differentiate into diverse specialized cell types
🗑
|
||||
| Differentiation | The structural and functional divergence of cells as they become specialized during a multicellular organism's development; dependent on the control of gene expression.
🗑

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.
