|---|---|---|---|---|---|
| Protein Synthesis | The creation or process of generating new proteins.
🗑
|
||||
| Polar Bodies | In females, out of the four gamete cells in meiosis, only one is used. The other three unused eggs are called polar bodies.
🗑
|
||||
| Meiosis | The formation of gametes. The 46 chromosomes are cut in half to 23. This produces sex cells.
🗑
|
||||
| Mitosis | The process by which the nucleus of a cell is divided into 2 identical parts. (46 chromosomes)
🗑
|
||||
| Nucleolus | Can be up to 4 in a nucleus. It is the site of rRNA synthesis, and then it joins with proteins.
🗑
|
||||
| Golgi Apparatus | Stacks of curved, membrane-bound sacs. It's function is to receive, modify, package, and distribute proteins and lipids coming from the E.R.
🗑
|
||||
| Transcription | The copying of RNA
🗑
|
||||
| Translation | The creation of the proteins.
🗑
|
||||
| Cilia | Project from the surface of the cell. Can range from 1 to thousands per cell.
🗑
|
||||
| Prophase | Longest phase of Mitosis. The chromatin become condensed and exist as chromosomes. Centrioles separate and spindle fibers form. The nuclear envelope breaks down.
🗑
|
||||
| Cytokinesis | Division of the cytoplasm. Cell division is now complete.
🗑
|
||||
| Anaphase | Centromere that joins sister chromatids split. Chromatids now separate and move to opposite ends of the cell.
🗑
|
||||
| Flagella | Structure is similar to cilia, but longer. Usually one per cell. In humans, it is only found on sperm cells.
🗑
|
||||
| tRNA | Transfers amino acids to the ribosomes, to help make the proteins.
🗑
|
||||
| mRNA | Makes a copy of the instructions.
🗑
|
||||
| Ribosomes | Where proteins are produced. Free ribosomes are unattached, while some are attached to the E.R.
🗑
|
||||
| Gametes | A male or female sex cell.
🗑
|
||||
| Plasma Membrane | The membrane of lipids or proteins that form either the outer edge of the cytoplasm of a cell, or the membrane that encloses a vacuole. Regulates what enters and leaves the cell.
🗑
|
||||
| Hypotonic | Lower concentration of solutes. (Higher water concentration)
🗑
|
||||
| Hypertonic | Solution with higher concentration of solutes, and therefore a lower concentration of water.
🗑
|
||||
| Isotonic | Concentration of solutes and water is equal.
🗑
|
||||
| Proteins | Chains of Amino Acids. Created in the ribosomes. The code for making proteins is found in DNA.
🗑

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.
