| cell membrane | the outer layer of a cell
🗑
|

| purpose of cell membrane | to control what goes in and out of the cell
🗑
|
||||
| cytoplasm | the gel-like substance that fills most of the inside of the cell
🗑
|
||||
| nuclear membrane | surrounds the nucleus, controlling what goes in and out of the nucleus
🗑
|
||||
| nucleus | the control center of the cell that contains the genetic material
🗑
|
||||
| organelles | parts of a cell that have specific functions
🗑
|
||||
| cell | the smallest unit of living things
🗑
|
||||
| Cell Theory | the idea that all living things are made of one or more cells and that cells reproduce to make more cells.
🗑
|
||||
| Germ Theory of Disease | the idea that germs (certain microbes) cause diseases
🗑
|
||||
| multicellular | organisms that are made of many parts with different functions that help the whole organism survive
🗑
|
||||
| cellular respiration | the process that all cells do that uses food (sugar) and oxygen to get energy
🗑
|
||||
| carbon dioxide and water | the waste products of cellular respiration
🗑
|
||||
| why we breathe | to get the energy from food (with cellular respiration)
🗑
|
||||
| semipermeable | describes the fact that membranes can let certain things in but stop others
🗑
|
||||
| mitochondria | where much of cell respiration takes place (in eukaryotes), converts energy for the cell
🗑
|
||||
| makes bread rise | yeast respiring and giving off carbon dioxide
🗑
|
||||
| zygote | fertilized cell
🗑

🗑
|
||||
| specialization | The process of cells taking on specific shapes and functions, different from many other cells of the same organism.
🗑
|
||||
| differentiation | The differences in cells in an organism. For example, skin cells are very different from nerve cells, which are very different from muscle cells.
🗑
|
||||
| organelles found in plant cells but not animal cells | chloroplasts and cell wall
🗑
|
||||
| advantage of cells being smaller | There is more total surface area, so the cell can absorb more nutrients and oxygen and get rid of wastes more easily.
🗑
|
||||
| "ingredients" for cellular respiration | oxygen and nutrients
🗑
|
||||
| main waste product from cellular respiration | carbon dioxide
🗑
|
||||
| virus | nonliving thing with genetic material that cause illness
🗑
|
||||
| unicellular | organisms that are made of just one cell
🗑
|
||||
| microbe | organisms too small to see without a microscope, could be one cell or more than one cell

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.
