Biology 5.1-5.2 Flashcards
process of arranging organisms into groups based on similarities
taxonomy
devised a simple, practical method of scientific classification
Carolus Linnaeus
an English clergyman who devoted much time to natural studies and became well known for his work with plants
John Ray
main groups
kingdoms
kingdoms are divided in to what
phylas
Each phylum is divided according to a different set of characteristics into what
classes
classes are divided into what
orders
the orders are divided into what
families
families are divided into what
genera
genera is divided into what
species
a group of similar organisms that are all descended from a single group of originally created organisms and may refer to a species, a genus, or a family
kind
system for assigning scientific names
binomial nomenclature
The what kind is usually broader than our
modern species
biblical
have membrane bound nuclei and membrane enclosed organelles
eukaryotes
green plants; multicellular eukaryotes that have cell walls and usually perform photosynthesis
Plantae
all fungi, including yeasts, molds, and mush rooms; multicellular eukaryotes that have cell walls and do not conduct photosynthesis
fungi
multicellular animals; eukaryotes without cell walls; usually can move and collect food
Animalia
eukaryotes that are not green plants, fungi, or multicellular animals; mostly unicellular organisms, such as amoeba, euglena, and paramecium
Protista
true bacteria, including common disease causing bacteria; prokaryotes with cell walls made of the substance peptidoglycan
Eubacteria
prokaryotes that do not contain peptidoglycan in their cell walls and have other key differences from true bacteria; many live in extreme environments
Archaebacteria
the six kingdoms are grouped into what
domains
the supposed evolutionary relationships of organisms.
phylogeny
assumes that how closely related two organisms are determines how many characteristics they have in common
cladistics
which depict all forms of life coming from a single life form
phylogenic trees
have vascular tissue for conducting water and minerals from the roots to the leaves and sugar from the leaves to all parts of the plant
vascular plants
includes angiosperms and gymnosperms
seed plants
includes ferns, mosses, and others
non-seed plants
including mosses and liverworts.
non-vascular plants
Plants that produce seeds
but do not produce flowers
gymnosperms
cone-bearing gymnosperms.
conifers
pollen producing cones
staminate cones
seed-producing cones.
ovulate cones
one of the biggest trees
Douglas Fir
some of the oldest living things on Earth
bristlecone pines
grows in Australia, has bright green leaves that are broad for a conifer
bunya-bunya
have unusual knobby textured bark and waxy, fern-like leaves. In size, they are comparable to other conifers
Wollemi pines
resemble palm trees, grow today only in certain tropical and subtropical regions
cycads
an oriental gymnosperm with two-lobed, fan shaped leaves
ginkgo
a small phylum of gymnosperms with varied characteristics
gnetophytes
