microorganisms Flashcards
define organisms
any living thing that can only be seen with a microscope
define micro
extremely small
define consumer/ hetetroph
make their own food
define producers/ autotrophs
get their food/energy from the sun
6 kingdoms of life
plants, animals, protists, fungi, archaebacteria, and eubacteria
what type of cells have NO nucleus
prokaryotic cells
what type of cells HAVE a nucleus
eukaryotic cells
3 basic shapes of bacteria
spirals, rods, and spheres
ways that eubacteria can be good
-they decompose dead stuff - they make: yogurt, cheese, buttermilk, vinegar, olives, pickles, and soy milk
ways eubacteria can be bad
-it can cause leprosy -can cause cholera -can cause pnemonia
ways we can stop or slow the growth of harmful when dealing with food
we can pasteurize the food
where is bacteria found
everywhere
what is in the animal like kingdom
amoebas and paramecium
what is the control in a science experiment
something that is kept the same in an expirament
what are variables
the differing amount or type that is changed by the scientist
where do protists live
in moist environments
sort fungi, protist, bacteria, and virus by size (smallest to largest)
viruses, bacteria, protist, and fungi
what did louis pasteur do
pasteurization (how diseases are spread)
what did Anton van Leeuwenhoek do
created the microscope
what did Edward Jenner do
created vaccine for small pox
what did Marie Curie do
studied radioactive
what did Alexander Fleming do
created pennicillin
what did Joseph Lister do
thought of the idea of washing your hands before doing surgery
what did Jonah Salk do
created vaccine for polio
diseases caused by protists
malaria, african sleeping sickness, and giardia
ways protists can be good
- it produces oxygen - it produces food - it produces toothpaste -DECOMPOSERS
how do fungi reproduce
spores
ways fungi can be helpful
- DECOMPOSERS - we eat them - penicillin is made out of it - helps plants grow healthy
ways fungi can be harmful
- death - white nose syndrome - poisonings - allergies - diseases
what is a lichen
composite organism
what type of kingdoms are involved with lichens
kingdom protista and kingdom monera
how does a virus reproduce
it attaches itself to a host cell
why are viruses not classified into one of the 6 kingdoms of life
Because they are not living, They require a host cell to function and cannot survive independently.
ways protists can be bad
- african sleeping sickness - malaria - giardia - red tide
where can you find archaebacteria
hot springs
what is in the plant like kingdom
red algae, brown algae, green algae, euglenoids, and dinoflagellates
what is in the fungi like kingdom
slime mold and downy midew
