Biology 12 3rd Exam Reviewer Exercise 9: The Prokaryotes Prokaryotes are subdivided into archaebacteria and eubacteria. Archaebacteria - no peptidoglycan in cell wall Ex. Halob acterium Eubacteria - has peptidoglycan in cell wall Eubacteria - can be differentiated by Gram staining Gram positive: purple-blue‚ mostly peptidoglycan susceptible to penicillin Gram negative: pink-red‚ less peptidoglycan‚ has lipopolysaccharides‚ susceptible to EDTA Gram negative can be further differentiated into

Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

The crab of Phylum Anthropoda is much more advanced and complex than the sponges of Phylum Porifera. One of the main differences that makes crabs more advanced is the fact that crabs have a body cavity which allows them to have different organ systems‚ this is called coelmate. A sponge does not posess a body cavity‚ which is called acolemate‚ but they do posess a Gastrovascular cavity. A Gastrovascular cavity has only one opening‚ the mouth/anus. Being a coelomate is more advanced because it allows

DOLP- Fungi General Structure and Function: For many years‚ fungi were classified into the plantae kingdom because the two kingdoms seemed to be alike; but now‚ we know that they are all too different. In fact‚ the fungi kingdom is more closely related to the animalia kingdom. Some of the only notable similarities between the fungi and plantae kingdoms are that they are both made of eukaryotic cells‚ both immobile‚ both contain cell walls (although made of different material)‚ and both evolved

------------------------------------------------- Annelid The annelids (also called "ringed worms")‚ formally called Annelida (from Latin anellus "little ring"[2])‚ are a large phylum of segmented worms‚ with over 22‚000 modern species including ragworms‚ earthworms and leeches. They are found in marine environments from tidal zones to hydrothermal vents‚ in freshwater‚ and in moist terrestrial environments.They are bilaterally symmetrical‚ triploblastic‚ coelomate organisms.They have parapodia

Through the concept of evolution‚ ecology‚ population‚ community and the environment. Species through different periods evolve physiologically and adapting to new environments. Animals who can’t live or survive in certain regions either migrate or die. Common ancestors often link to present day organisms showing biologically and different

This type of creature actually has many types of animals within its phylum. The phylum of the creature has a few different creatures and numerous types of jellyfish. To focus upon the creature I would like to focus on three types: Hydrozoans‚ Jellyfish‚ and Sea Anemones. The Hydrozoa is a subgroup of the Cnidarian that constantly
