QuestionAnswer
Name the rules for Binomial Nomenclature Rules--The first letter of the genus name is always capital and the rest are lower case, when printed it is italicized, when hand written it should be underlined.
List the Taxonomy Groups Domain-broadest Kingdom Phylum Class Order Family Genus Species-most specific
Name the three domains and kingdoms with them The three domains are Bacteria, Archaea, and Eukarya. The six kingdoms are Bacteria, Archaea, Protists, Fungi, Plantae, and Animalia. Eubacteria are prokaryotes whose cell walls contain peptidoglycan.
Explain the difference between bacteria and archaea Eubacteria-Very strong cell walls, Contain peptidoglycan, some have a second cell wall. They can live mostly anywhere except extreme environments. Archaebacteria live in three different environments which are 1. Thermoacidophiles live in hot, acidi
Shapes and names of bacteria 1. Spherical=Cocci 2. Rod-shaped=Bacilli 3. Spiral-shape=Spirochetes
Know the three extremophiles Thermoacidophiles live in hot, acidic environments Halophiles live in very salty environments Methanogens cannot live in the presence of oxygen.
Bacterial survival individually and population The endospore helps them survive extreme heat, extreme cold, dehydration, and large amounts of ultraviolet radiation. On a population level they survive on mutations. This leads to new gene combinations, new characteristics, and genetic diversity.
Three ways bacteria are beneficial Nutrient cycling and nitrogen fixation. Bacteria are decomposers, returning vital nutrients to the environment. Nitrogen-fixing bacteria live in a symbiotic relationship in the root nodules of plants such as soybeans, clover, and alfalfa
Three reasons viruses are not living Viruses is a nucleic acid surrounded by a protein coat, do not have cells, and are not considered to be living things.
How protist are classified, why might that change, and the three groups of protist All protists are eukaryotes Some reproduce asexually by mitosis while others exchange genetic material during mitosis. Classified by the way they obtain their nutrients Protozoans are heterotrophs and usually ingest bacteria, algae, or other protozoans

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
