Biology Revision 1

QuestionAnswer
What is DKPCOFGS? Domain, Kingdom, Phylum, Class, Order,Family, Genus, Species D King Philip Comes Over For Great S..
What is DKPCOFGS replaced by? Phylogenetics, so based on monophyletic groups (group that have common ancestors)
What are the 3 domains? 1- Archaea (Prokaryotes) 2- Bacteria (Prokaryotes) 3- Eukarya (Eukaryotes) Reminder that prokaryotes DON'T have a nucleus while eukaryotes do
What are the 4 kingdoms? Sous-catégorie de Eukarya domain: 1-Fungi 2-Plant 3-Animalia 4-protists (no MAJ)
What are the characteristics of Archaea domain? They were the first life form. Small, simple cells found in extreme conditions, but also elsewhere. They have dif. biochem to other bacteria and DON'T have cell walls made of peptidoglycan.
What are the characteristics of Bacteria domain? Small, simple cells. Found everywhere. Some cause diseases, many are essential life forms. Cell walls made of peptidoglycan.
What are the charactetistics of Eukarya domain? Large, complex cells with membrane bound nucleus and organelles.
What are the characteristics of protits kingdom? Example of protists? Large eukaryotic cells, usually unicellular or living in colonies. Varied life strategies. Ex: Amoeba, malaria parasite
What are the characteristics of Fungi kingdom? Examples? Large eukaryotic cells, unicellular or multicellular. Cells organised in strings called hyphae (resemble muscles cells.) Cells have chitin cell walls. They are heterotrophic=feed by absorption. Ex: yeast, mushroom
What are the characteristics of Animal kingdom? Large eukaryotic cells, usually multicellular. Heterotrophic= feed by ingestion. NO CELL WALLS
What are the charactetistics of Plant kingdom? Large eukaryotic cells, unicellular or multicellular. Autotrophic=photosyntesis. Cellulose cell walls
What are the evolutionnary relationship between the 4 kingdoms? Archaea=1st form of life Fungi resembles animals= common ancestor Plants separated from animal/fungi early on Eukaryotic cells come from Archaeal ancestor that lost cell wall and formed doucle membrane nucleus
Explain the emdosymbiosis theory. internalization of prokaryotes by ancestral eukaryotic cells that resulted in chloroplast and mitochondria
Nomenclature? Genus (Homo)= MAJ species (sapiens)= lower case
Created by: Malayka

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.
