Lab Q1 Flashcards
How many cells in our body’s?
50-100 trillion
What are the two main types of cells?
Prokaryotic- no defined nucleus
Eukaryotic- have a nucleus/more complex
What three domains do we use to classify organisms?
Bacteria, archaea, eukaryota
Traveling to from the bottom of the tree of life to the top would take how many years of evolution?
4 billion years of evolution
How many zooms in the tree of life to find humans?
4
Where are cells found?
Single called organisms to multicellular plants and animals.
Briefly describe Archeae
Single celled organisms that are prokaryotic, live in extreme environments
Where do some Archeae live?
Salt lakes, hot springs, oceans, plankton, soil, asshole
What’s does anaerobic mean?
Don’t need oxygen
Describe domain bacteria
Single celled, prokaryotic, absorbs food from environment
What are the types of bacteria and how do they get there food?
Autotrophic- make own food
Heterotrophic- outside source, can’t make food
Saprophytic- dead organic matter
Parasitic- inside of bodies, cause diseases
How do we use bacteria?
Food, medicine, genetic engineering, digest food, vitamin k
How do bacteria cause diseases?
Pathogenic-destroys cells and tissue
What do bacteria look like?
Cocci- balls
Rod
Spiral
What is Domain Eukarya.
Includes unicellular eukaryotes and multicellular eukaryotes
How many kingdoms are in the domain Eukarya?
4
Protista, fungi, plantae, animalia
Briefly describe kingdom Protista.
Unicellular eukaryotes, mostly single celled creatures
What are the 3 types of Protista?
Animal like Protists- flagella, cilis, ingest food
Fungus like Protists- heterotrophic, mold
Plant like Protists- photosynthesis ingest
Who supply’s half he worlds O2?
Protists
Name 2 diseases of Protists.
Malaria, African sleeping sickness
What are 3 examples of Protists that we looked at in class?
Diatoms, amoeba, paramecium
Briefly describe kingdom fungi
Heterotrophs and decomposers
Give two ways we use fungi?
Bread, alcohol
What are lichens?
Kingdom fungi, 2 organisms living together,
What does each organism contribute in lichens?
Fungi host- absorb water, minerals, anchors to substance
Algae- photosynthesis
Give several examples of kingdom plantae, domain Eukarya
Grass, tress, moss, elodea-aquatic plant, onion root tip
How do plantae obtain food?
Autotrophs
Guve examples of kingdom animalia
Dogs, fish, humans
What is binary fission and what domain uses it?
Common form of replication in parrokaryotics
