Gnathostomata
Adaptation to Terrestrial Lide
Mammals: Females have mammary glands (produces milk), have developed brains and hair has multiple functions
Placenta mammals
Marsupials
Monotremes
Birds: Endothermic (constant body temperature) and has four chambers to the heart
Reptiles:Have body scales that create a waterproof barrier that helps prevent dehydration in dry air
Amphibians:Use their moist skin to assist in gas exchange
Fish:have a skeleton of cartilage rather than bone.
Agnethanos
Angiosperms
-Reproduce using flowers, and their seeds are contained in a fruit
Birch trees
Gymnosperms
-Seeds that are exposed on the surface
Coniferous trees
-These plants do not have vascular tissue, and they are dependent on the processes of diffusion and osmosis to transport nutrients
Hornworts (Phylum Anthocerophyta)
Liverworts (Phylum Hepatophyta)
Mosses (Phylum Bryophyta)
-Gametophytes were reduced to tiny, short-lived structures that depend on moisture to carry out sexual reproduction.
Horsetails (Phylum Sphenophyta)
Club mosses (Phylum Lycophyta)
Whisk ferns (Phylum Psilotophyta)
Euglenoids
-Have chloroplasts and conduct photosynthesis, they also have flagella and can absorb nutrients -Autotrophs in sunlight and heterotrophs in the dark
Euglena gracilis
Dinoflagellates
- Have two flagella
Gonyaulax catenella
Diatoms
-Single celled, aquatic -Rigid cell walls with an outer layer of silica -Asexual reproduction
Sporozoans
-parasites of animals, taking the nutrients they need from their hosts
Malaria
Ciliates
-Use cilium for sweeping food and for movement (hair like)
Paramecium
Cercozoans
- Use pseudopods for feeding and locomotion
Amoeba
Flagellates
-Use flagellum for food and movement (tail-like)
Water molds
- Filamentous organisms - extend threads into their host and release digestive enzymes and absorb the resulting nutrients.
Plasmodial slime molds
- Contains many nuclei -feed by engulfing small particles of food into their cytoplasm
Cellular slime molds
-One nucleus each - form pseudoplasmodium when food is scarce
-Release hyphae,"basidia"
Mushrooms
- Develop sacs, asci, during sexual reproduction
Yeast cells
-Mostly unicellular and aquatic (spores have flagella) -Can be parasites or live on decaying plants or insects
Synchytrium endobioticum
Usually do not reproduce sexually and are very diverse
Penicillium
NO Nucleus or membrane-bound organelles
Also have several chemical types of cell walls
They're the oldest organism on the planet
Lives in the most inhospitable areas
Lives in very hot, salty, and acidic conditions
Single-Celled prokaryotic
NO Nucleus or cell membrane or organelle
Have a very rigid cell wall
Capable of withstanding super rough environmental conditions
