Biological Diversity
Diverse species throughout the world. There are 1 million species on the planet. These species
are catagorized by broad to detailed.
Domains
a taxonomic category above the kingdom level; the three domains of life are Archaea, Bacteria,
and Eukarya
3 Domain Names
1. Domain Bacteria 2. Domain Archaea 3. Domain Eukarya
Every living thing (that we know of) belongs to one of these categories.
Domain Bacteria
(simple) Prokaryotes. most abundant life form.
prokaryote
dont have any organelles (means that w/n organism theres no smaller compartments) see this
image under microscope.
Domain Archaea
also prokaryotes (but not bacteria). unlike bacteria b/c live in unbarable condi*ons like hot
springs & volcanoes.
Domain Eukarya
eukaryotes. Includes pro*st(a), plants, fungi, and animals.
eukaryotes
organisms made up of one or more cells that have a nucleus and membrane-bound organelles.
Under a microsocpe you can see many of these compartments. These compartments provide
services for the cell. These can turn into complex organisms. looks like this under microscope.
pro*st(a)
usually single celled things.
, plantae
photosynthesise
fungi
range from mushrooms to athletes foot to STDs. Classified by their type of reproduc*on.
animalia
usually cri2ers bigger than 1 cell. [ex] cats, dogs, humans. they are mul*cellular (as opposed to
a pro*st)
a cell
smallest unit of living ma2er. seperated from external environment by membrane(s). all living
things are composed of these.
evolu*on
Species change over *me by a means of natural selec*on. species have to change in order to
survive in their environment.
Charles Darwin's Theory of Evolu*on
pulished theory in 1850's. He called it DESCENT W/ MODIFICATION (things change throughout
genera*ons). Organisms adapt to their environment. Each organisms have challenges that cause
them to modify their condi*ons.
natural selec*on
species either live long enough to pass on their genes, or dont.
Biology as a Real Science refers to...
using the scien*fic method to help solve whats causing curiosity.
5 steps of scien*fic method
1. make observa*on 2. ques*ons (about your observa*on) 3. make up a hypothesis (educated
guess) 4. make predic*on 5. test/expirament (to see if your predic*on or hypothesis will work, if
fails, have to make a new predic*on or hypothesis).
biology
the study of organiza*on
How is life organized?
