Question

For the following question, please answer in essay format( a page and half long minimum)( if hand written please print legibly and be clear about which part of the question are answering, in complete sentences, with as much detail as possible. Thanks!

The taxonomic system proposed by Carl Woese (in 1977) recognizes two prokaryotic kingdoms and

four eukaryotic kingdoms. List these six kingdoms, along with their distinguishing characteristics, and

describe any biochemical substances that could be used to classify living things into each of these kingdoms.

Answer 1

The two paryotic kingdoms proposed by Carl Woese are Eubacteria and Archaebacteria. The four Eukaryotic kingdoms are Protista, Fungi, Plantae and Animalia.

Archaebacteria is the most oldest living organisms on earth. They are prokaryotes and unicellular. The Eubacteria are more complex and common. Eubacteria can live in more neutral conditions than Archaebacteria.

Protista are simple, predominately unicellular eukaryotic organisms. Examples include slime moulds, algae and protozoans.

Fungi are unicellular or multicellular organisms with eukaryotic cell types. The cells have cell walls but are not organized into tissues. They do not carryout photosynthesis and obtain nutrients through absorption. Examples are sac,fungi, yeasts and mould.

Plantae kingdom contain plants which are multicellular organisms composed of eukryotic cells. They obtain nutrients by photosynthesis and absorption. Examples are Mosses, ferns, conifers and flowering plants.

Animalia contain animals which are multicellular organisms composed of eukaryotic cells. The cells are organized into tissues and lack cell walls. They do not carryout photosynthesis and obtain nutrients primarily by injestion. Examples are sponges, worms,insects and vertebrates.
