Products Of Evolution Flashcards
Thoroughly describe the organisms in the kingdom Animalia.
Eukaryotes, multi-cellular, complex, specialized cells, internal digestion, nervous system, heterotrophs
Thoroughly describe the organisms in the kingdom Protista
single celled eukaryotes, help most all single celled heterotrophs and autotrophs, sexual and a sexual reproduction
Thoroughly describe the organisms in the kingdom prokaryote (bacteria)
single celled prokaryotes, bacteria, single cells, no organelles, some autotrophs, a sexual reproduction
Thoroughly describe the organisms in the kingdom fungi
eukaryotes, grow from spores, do external digestion, most multicellular, sexual and a sexual reproduction
describe how organisms were divided from 1.Prokaryote 2.Plantae 3.Fungi, Animalia
- membrane band organelles? yes/no
- photosynthesis or not
- reproduce from spores or not/ or internal/external digestion
terms: place in order from largest to smallest: kingdom, order, class, phyla, family, species, genus
kingdom, phylum, class, order, family, genus, species
six unifying principals of biology:
evolution, homeostasis, energy matter organization, continuity, development, ecology
As you work from a kingdom to a species, what happens to the degree of relatedness between organisms?
The organisms become more closely related
One important and very telling characteristic of two organisms if they are the same species is that they will __________
interbreed and produce fertile offspring
Broccoli, cauliflower, cabbage, Brussels sprouts and kohlrabi are all classified as Brassila Oleracea what does this mean?
There are multiple varieties of the same species, these are a result of selective breeding in agriculture
list several reasons why scientists assign scientific names rather than just a common name
- different languages
2. some common names are misleading ex: “starfish”
Does our system for classifying species change over time?
Yes, as we make new discoveries, we adjust the system to reflect it
Which kingdom has the simplest and earliest organisms?
Prokaryote
What do scientists use to classify organisms?
structural and physical data, includes DNA, which is becoming the most important characteristic
Which contains more species a family or class?
a class is larger and contains more species
What does a genus consist of?
a group of closely related species
Describe binomial nomenclature
2 Latin names
1st: genus
2nd: species
When did scientists start using phylogenetic tress?
1930’s and 1940’s
What types of adaptations are important for plants to survive on land?
- waxy material
- vascular tissue
- seeds
- photosynthesis
- internal sexual reproduction
How do vascular plants get water from the environment?
Plants with a plumbing system-use roots to get H2O from the environment
What is an autotroph? How do they feed themselves?
self eater: they feed themselves by photosynthesis
What is a heterotroph? How do they feed themselves?
other eater: they rely on other organisms to get their food
What do all protists have in common?
all are eukaryotes, live in moist habitats, grab bag
Thoroughly describe the organisms in the kingdom Plantae
eukaryotes, do photosynthesis, have cell walls, sexual reproduction and a sexual reproduction
What is Phylogeny?
Evolutionary history f organisms based on inherited features
What is taxonomy?
classifications and naming of living organisms
Describe prokaryote and eukaryote
Prokaryote: no organelles, bacteria
Eukaryote: has organelles, higher order, everything other than bacteria
