|---|---|---|---|---|---|
| virus | a structure that contains strands of DNA or RNA surrounded by a protective protein coat; it cannot live independently outside of cells
🗑
|
||||
| capsid | the outer protein layer that surrounds the genetic material of a virus
🗑
|
||||
| replication | the fundamental process of all cells, in which the genetic material is copied before the cell reproduces
🗑
|
||||
| lytic cycle | the replication process in viruses in which the virus's genetic material used the copying machinery of the host cell to make new viruses
🗑
|
||||
| lysogenic cycle | the replication process in viruses, in which the viral DNA enters the host cell's chromosome; it may remain dormant and later activate and instruct the host cell to produce more viruses
🗑
|
||||
| prion | an infectious particle that causes damage to nerve cells in the brain, and that appears to consist mostly or entirely of a single protien
🗑
|
||||
| bacterium (bacteria) | an individual prokaryotic cell or a single species that is in the domain Bacteria
🗑
|
||||
| archaeon (archaea) | an individual prokaryotic cell or a single species that is in the domain Archaea
🗑
|
||||
| bacillus (bacilli) | a micro-organism whose overall morphology is rod-shaped
🗑
|
||||
| methanogenesis | a biological (or chemical) process that produces methane as an by-product
🗑
|
||||
| extremophile | an organism that lives in habitats characterized by extreme conditions
🗑
|
||||
| mesophile | an organism that lives in habitats characterized by moderate conditions
🗑
|
||||
| binary fission | the asexual form of reproduction used by most prokaryotes (and some eukaryotic organelles), in which a cell divides into two genetically identical cells (or organelles)
🗑
|
||||
| conjugation | a process in which there is a transfer of genetic material involving two cells
🗑
|
||||
| endospore | a dormant bacterial cell able to survive for long periods during extreme conditions
🗑
|
||||
| Gram stain | a stain that separates bacteria into two major divisions (Gram positive and Gram negative) based on the cell wall's response to the stain
🗑
|
||||
| endosymbiosis | theory that explains how eukaryotic cells evolved fro the symbiotic relationship between two or more prokaryotic cells
🗑
|
||||
| endosymbiont | a cell that is engulfed by another cell in endosymbiosis
🗑
|
||||
| host cell | a cell that engulfs another cell in endosymbiosis
🗑
|
||||
| protist | a eukaryotic organism, usually unicellular, that is not a fungus, plant, or animal
🗑
|
||||
| parasite | an organism that benefits by living in or on another organism at the expense of that organism
🗑
|
||||
| pseudopod (pseudopodia) | a temporary cytoplasmic extension that amoebas use for feeding and movement
🗑
|
||||
| cilium (cilia) | a short, hair-like projection that functions in cell movement and particle manipulation when coordinated with other cilia
🗑
|
||||
| flagellum (flagella) | a long, hair-like projection extending from the cell membrane that propels the cell using a whip-like motion
🗑
|
||||
| red tide | a coastal phenomenon in which dinoflagellates that contain red pigments are so concentrated that the seawater has a distinct red colour
🗑

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.
