Evolutionary Past Cyanobacteria
Blue- green algae
Photosynthetic
Responsible for the marked increase in Oxygen 2000 million years ago<br>
03
Cyanobacteria Evidence DNA shows the first green plants evolved from prokaryotes between 2500 and 1000 million years ago.
Same chlorophyll in algae and land plants.<br>
04
Endosymbiosis a symbiotic relationship between two organisms in which one of the two organisms (the endosymbiont) lives inside the body of the other one (the host).<br>
05
Classification of Plants Kingdom - Plantae
Division (-phyta)
Class (-opsida)
Subclass (-idae)
Order (-ales)
Family (-aceae)
Genus
Species (Genus + specific epithet)<br>
06
Magnolia grandiflora Plantae--includes all plants
Magnoliophyta--flowering plants
Magnoliopsida--dicots
Magnoliidae--subclass for Magnolia-like plants
Magnoliales--order for Magnolia-like plants
Magnoliaceae--family for Magnolia-like plants
Magnolia--genus that includes all Magnolias
grandiflora--specific epithet<br>
07
Circumscription of Features A new condition is added at each step to set up a category that is MOST specific.
Example:
Things with wheels = buses, cars, bicycles, skates, airplanes, trains, etc.
And is ground transport = buses, cars, bicycles, trains
And can carry more than one person = buses, cars, trains
And runs on rails = trains
Classes of Angiosperms Monocotyledonae (Monocots)
Very few are annuals
Lilies, grasses, cattails, palms, yuccas, orchids, irises
Dicotyledonae (Dicots)
More primative, 1/6 are annuals
Almost all kinds of trees and shrubs
Snapdragons, mints, peas, sunflowers<br>

Parts of the flower PISTIL
Stigma
Style
Ovary
STAMEN
Anther
Filament becomes the seed becomes the fruit<br>
