Test 1 - DIVERSITY Flashcards
Who is the father of taxonomy
Carlos Linnaeus
7 Classification levels
Kingdom phylum class order family genus species
what are the three domains
domain archea, domain bacteria, domain eukarya
6 kingdoms of life
eubacteria archaebacteria fungi protista animilia plantae
3 definition of species
morphological- physical characteristics
biological - reproduction
phylogenetic - using evolutionary history
characteristics of bacteria
prokaryotes, smaller than eukaryotic cells, no nucleus or organelles
what are the three shapes of bacteria
spherical cocci. rod shaped bacilli. spiral spirilla
difference between prokaryotic cells and eukaryotic cells
eukaryotes are bigger, have a true nucleus and complex organelles
parts of bacterial cells and their functions
flagellum - movement
capsule- lets bacteria stick to one another
pillus- hairlike that help attach to its host transfer DNA
Benefits of education why sexual reproduction is important
Conjugation is good because it changes the DNA in the cell which helps with diversity if the certain cells not surviving good the conjugation will create new cells with DNA that could help them survive the conditions
Transformation and transduction
Information when a sell picks up loose DNA from its surroundings
Transduction when viruses infect bacteria and carry genes from one cell to another
good bacteria does …
its majority of our bodys cells, they decompose, and produce vitamins
bad bacteria
cause desieses, infections, realizing toxins into the body, invading and killing cells
are antibiotics used on just bacteria
they can only be used on infections caused by bacteria
what kingdom came first
archaebacteria
why are viruses non living
lifeless particle, no metabolic process, doesn’t produce or release energy, cannot reproduce, requires a host cell to function.
name of virus that affects bacteria cells
bacteriophages
why do we get vaccines each year
inserting weakened forms of viruses to help build immunity, every year because there can be changes to the virus
lytic acronim
APRAR attach, penetrate, replicate, assemble, release
Protista characteristics
unicellular, eukaryotic, reproduce asexually, thrive in moist enviroments
fungi characteristics
heterotrophs, eukaryotic, cycle nutriens, reproduce by buddying
symbotic relationship
a releashionship between 2 organisms where they both benefit
plantae characteristics
eukaryotic, multicellular, carry out photosynthesis, cell walls
asexual reproduction in plants (vegetive repro)
Where is produced. Disposable divide and grow into a new plant
Gymnosperms in brackets cones
cones for reproductive tool, sexual reproduction occurs between male and female cones in these plants
Angiosperms brackets flowers
Flower, reproduce sexually through pollination, seeds are protected with walls of fruit
difference between vascular and non vascular plants
vascular- taller, tissues to transport water and nutiens, spores or seeds to reproduce
non vascular- lack true roots, no tissues, reproduce sexually or asexually
anamalia characteristics
heterotrophs, multicellular, eukaryotes, cells lack cell walls but have cell membranes, nerve and muscle tissue, most reproduce sexually
how food chains and ecosystems can be affected if a species is lost
species can become extinct or gradually disappear because of lack of prey/food
