| The process in which nutrients are broken down releasing the chemical energy stored in them. | Cellular Respiration
🗑
|
||||
| A green organelle in plant cells containing chlorophyll; where photosynthesis takes place. | Chloroplast
🗑

| A body structure made of different kinds of tissues combined to perform a specific function. | Organ
🗑
|
||||
| Several organs working together to perform a specific function. | Organ System
🗑
|
||||
| A structure within a cell that carries out a specific function. Name means "tiny organ." | Organelle
🗑
|
||||
| Made of cellulose and surrounds plant cells. Main function is to prevent loss of water but also provides structural support. | Cell Wall
🗑
|
||||
| Packages proteins for transport out of cell. typically located near the cell membrane | Golgi Body (apparatus)
🗑
|
||||
| Gel like substance inside the cell between the cell membrane and nucleus. | Cytoplasm
🗑
|
||||
| The DNA of the cell, as it appears during mitosis, in its coiled and dense form. | Chromosomes
🗑
|
||||
| The DNA of the cell as it appears during the portion of the cell cycle when the cell is carrying out its normal life functions. | Chromatin
🗑
|
||||
| The idea that all living things are basic structure of form and function are cells, cells only arise from other cells | Cell Theory
🗑
|
||||
| Cells develop in different ways to perform different functions. | Cell Specialization
🗑
|
||||
| One of two structures found only in animal cells. Play important role in mitosis making the spindle fibers. | Centriole
🗑
|
||||
| Membrane surrounding the nucleus of plant and animal cells. | Nuclear Envelope.
🗑
|
||||
| "The brain of the cell." Contains the genetic information of the cell. | Nucleus
🗑
|
||||
| Site of ribosome production inside the nucleus. | Nucleolus
🗑
|
||||
| Name means "storage sac." Rarely found in animal cells, large in plant cells and store food, water and wastes. | Vacuole
🗑
|
||||
| Tiny two part structure in the cytoplasm that is envolved in protein synthesis in association with the rough ER. | Ribosomes
🗑
|
||||
| Protein filament network that helps a cell maintain its shape. | Cytoskeleton
🗑
|
||||
| The mass of a given substance being dissolved (solute) in a given volume of a solvent (the substance doing the dissolving). | Concentration
🗑
|
||||
| The movement of a substance from high concentration to low concentration. | Diffusion
🗑
|
||||
| The diffusion of water. | Osmosis
🗑
|
||||
| The transport of lager molecules through protein channels in the cell membrane. | Facillitated Diffusion
🗑
|
||||
| The concentration of solutes is the same inside and outside the cell. Equilibrium. | Isotonic
🗑
|
||||
| Solution outside the cell has a higher concentratiion than inside the cell. Water is lost. | Hypertonic
🗑
|
||||
| Solution outside the cell has a lower concentration than inside the cell. Water gain. | 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.
