Lycophyta

Comes in 3 different shapes: coccus,bacillus or spirillum

Has a cell wall which containspeptidoglycan

It is either arranged in: Diplo (pairs),Statphlo (Clumps) or Strapto (strings)

Most are heterotrophic

Are either: Obligate Aerobes (bacteria thatneed oxygen to live), Facultative Aerobes

Their lifestyle is either: unicellular, colony orfilamentous

they inhabit extreme environments such ashot springs, arctic ice, highly acidic water,intestines of mammals

They do not cause diseases unlike bacteria

oldest organism on earth

cell membrane and cell wall lackpeptidoglycan

reproduces through binary fission andconjugation

has no cell wall

single or multi cellular organisms

genetic material organized into a nucleus

possess organelles

huge range in diversity

are enclosed by a cell wall

warm blooded

high metabolic rate

have hair on their bodies

produce milk through mammary glands tofeed their youngs

have a single bone in their lower jaw

have three middle ear bones

Examples: Echidnas, Duck billed platypuses

most of the young children are carried inpouches

A young marsupial is born after only a fewweeks as an embryo

It has large front paws that it uses to climbthrough the mother's fur to reach thepouch.

Examples: Kangaroos, Koalas, Possums,Wombats and Tasmanian devils

Largest group

have 4000 different species

Examples: Humans, elephants, whales,shrews, dogs and cats, horses, cattles

exchange of nutrients and wastes betweenthe blood of the mother and that of thefetus

The placentals include all living mammalsexcept marsupials and monotremes.

1. Hexapoda

2. Crustacea

3. Chelicerata

Examples: Ascidians, Copelata, Larvacea

Are prokaryotic

Are unicellular

contains peptidoglycan layer

autotrophs/ heterotrophs

does binary fission as its primary means ofreproduction

Three morphologies: cocci, rod and spiral

Cocci: diplo

Rod: Mycobacteria

archaea cell walls and cell membranes are much more resistant to physical andchemical disruptions

Archaea contains polysaccharides andproteins

Lacks peptidoglycan

Unicellular and prokaryote

Autotroph/Heterotroph

Representative species: Methanogens, halophiles, extreme thermophiles andphyscrophilles

Eukaryote

Unicellular or multicellular

cellulose in some; occasionally no cell wall

autotrophs/ heterotrophs

reproduce asexually/sexually

Gymnosperm: (ex: cycas)

Photoautotrophs chloroplasts: can dophotosynthesis and eat food.Heterotrophs. Mixotrophs threefeeding approaches have arisenindependently multiple times

The three feeding strategies are: animallike, fungilike and plantlike protists

Are eukaryote

Mostly multicellular

Cell wall made from chitin

Mostly heterotrophs

Usually reproduce sexually

5 major phyla: Chytridiomycota,Zygomycota, Glomeromycota, Ascomycota,Basidiomycota

major decomposers on earth, produceimportant antibiotics and are naturalpesticides

3 types of fungal nutrition: Parasitic,Predatory and Mutualistic

have chloroplasts that contain chlorophyll

cell walls which are rich in cellulose

Plants are generally autotrophic

oxygen evolving photosynthesis

Bryophytes: (ex: rica)

Seedless vascular: (ex: clubmosses)

Angiosperm: (ex: sunflower)

are eukaryote

multicellular

heterotrophs: feeds on plants,animals ,fungi, protists and each other

use oxygen for aerobic respiration

do not have a cell wall

usually motile or the ability to move inatleast one stage of their life

reproduce sexually

produce an embryo that undergoes stages

Examples: Jawless vertebrates, Lampreys

Example: Cartilaginous fish

Examples: Bony fish

Examples: Amphibians

Examples: reptiles

Example: Birds

Example: mammals
