DISCUSSION Bryophytes are seedless plants without specialized water conducting tissues. Bryophytes include mosses (phylumBryophyta)‚ liverworts (phylum Marchantiophyta Hepatophyta)‚ and hornworts (phylum Anthocerophyta). They are plants that virtually everyone has seen‚ but many have ignored. The most commonly encountered group is the green mosses that cover rotting logs‚ anchor to the bark of trees‚ and grow in the spray of waterfalls‚ along streams and in bogs. Even though mosses often thrive in

Division: taxonomic term used instead of phylum to group related classes of plants and bacteria 5. Domain: taxonomic group of one or more kingdoms 6. Family: taxonomic group of similar‚ related genera that is smaller than a genus and larger than an order 7. Genus: taxonomic group of closely related species with a common ancestor 8. Kingdom: taxonomic group of closely related phyla or divisions 9. Order: taxonomic group that contains related families 10. Phylum: taxonomic group of related classes

1 of the Phylum Caminalcula. However through the fossil reconstruction‚ the construction of a phylogenetic tree‚ in Exercise 2 Part 4‚ it appeared that organisms 12‚ 2‚ 22‚ 3‚ 4‚ and 9 are closer related to organisms 19 and 20 than otherwise thought in Exercise Part 1. So in Exercise 2 Part 5‚ the orders and families were switched. Also through the fossil reconstruction showed homoplasy. Homoplasy is a characteristic shared by a species but is not common in its ancestors. In the Phylum Caminalcula

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
