Taxa
|
Dumb Kings Play Chess On Green Sand.
•Domain •Kingdom •Phylum •Class •Order •Genus •Species |
|
|
Systematics
|
The study of evolutionary relationships.
|
|
|
Eukaryotes
|
•Chromosomes are long, linear DNA with histone protein.
•Nucleus •membrane organelles •flagella and cilia with Tubulin in (9+2) arraignment. |
|
|
Prokaryote
|
•Circular plasmid DNA
•no nucleus •no membrane organelles •flagella made from flagelin. |
|
|
Facultative anaerobe
|
Grows in the presence of oxygen but can switch to anaerobic respiration when O2 is absent.
|
|
|
Domain Archea differs from the other domains by the following
|
1. Cell walls are not peptidoglycans(bacteria) or cellulose(plants) or chitin(fungi).
2. Archeal plasma membranes contain different phospholipids. |
|
|
Domain Archea is similar to eukaryotes by the following
|
1. DNA both have histones; bacteria does not.
2. Ribosome in both Archea and eukaryotes is not inhibited by antibiotics streptomycin and chloramphenicol. As it is in bacteria. |
|
|
Major groups of domain Archea.
|
1. Methanogens - obtain energy from H2 and fixing CO2.
2. Extemophiles. - halophiles(salt) and thermophiles(heat). |
|
|
Domain Bacteria classified into three shapes.
|
Cocci -spherical
Bacilli - rod Spirilla - spirals |
|
|
Bacteria are distinguished into two major groups by their cell wall.
|
Gram positive - thick peptidoglycan wall. Gram negative - thin peptidoglycan wall.
|
|
|
Common groups of bacteria include.
|
•Cyanobacteria - photosynthetic with accessory pigments call phycobilins and nitrogen fixing enzymes called heterocysts.
•Chemo synthetic bacteria. •Nitrogen fixing bacteria. •Spirochetes - move in a corkscrew motion. |
|
|
Domain Eukarya kingdoms?
|
•Kingdom Protists.
•Kingdom Plantae. •Kingdom Fungi. •Kingdom Animalia. |
|
|
Animal Phyla
|
Porifera, Cnidaria, platyhelminthes, Nematoda, Rotifera, Mollusca, Annelida, Arthropoda, Echinodermata, and Chordata.
|
|
|
Pronto some vs deutersome
|
Protosome - spiral cleavage, archenteron mouth, coelom from split in tissue at sides or archenteron.
Deuterosome - radial cleavage, archenteron anus, coelom from outpouching or archenteron wall. |
|
|
Archenteron
|
Internal cavity formed when blastula folds in.
|
|
|
Coelom
|
A liquid filled cavity forms from mesoderm. It serves to cushion the internal organs and allows for their expansion and contraction.
|
|
|
Eumetazoa vs Parazoa
|
Eumetazoa cells organized into tissues and posses germ layers.
Parazoa lack tissues and do not develop organs. |
|
|
Kingdom protista
|
Organisms in this kingdom may be algae like, animal like, fungus like, unicellular, or multicellular.
|
|
|
Tubulin
|
Flagella in eukaryotes.
|
|
|
Flagellin
|
Flagella is composed of in prokaryote.
|
|
|
Radial symmetry vs bilateral symmetry
|
Radial symmetry(cnidarians) gives rise to dipoblast(ecto and endoderms) whilst bilateral symmetry gives rise to trip oblast. Sponges are unique because they only have single germ layer.
|

|
Radial symmetry vs bilateral symmetry
|
Radial symmetry(cnidarians) gives rise to dipoblast(ecto and endoderms) whilst bilateral symmetry gives rise to trip oblast. Sponges are unique because they only have single germ layer.
|
|
|
Endoderm
|
The endoderm forms: the digestive system, the liver, the pancreas, the urinary bladder, the epithelial parts of the trachea, the lungs, the thyroid, the parathyroid.
|
|
|
Mesoderm
|
The mesoderm forms: muscle (smooth and striated), bone, cartilage, connective tissue, adipose tissue, circulatory system, lymphatic system, dermis, genitourinary system, serous membranes, and notochord.
|
|
|
Ectoderm
|
Nervous system, eyes, teeth, skin and hair.
