- Prokaryotes Vs Eukaryotes
While eukaryotic cells and prokaryotic cells have some characteristics in common, they diverged from their common ancestor billions of years ago, thus accounting for significant differences in overall structure and function. Here we will go over them....
- Prokaryote V.s. Eukaryote Paragraphs
Alexandra RodenNovember 18, 2014Period 3Prokaryote v.s. EukaryoteCells are the basic unit of life as we know it. There are two main categories of cells, Prokaryote and Eukaryote. Both kinds have similarities as well as drastic differences.Both categories...
- Bacterial Gene Numbers Range Over An Order Of Magnitude
KEY CONCEPTS:Genome sequences show that there are 500-1200 genes in parasitic bacteria, 1500-7500 genes in free-living bacteria, and 1500-2700 genes in archaea. Large-scale efforts have now led to the sequencing of many genomes. A range is summarized...
- Unicellular Organism
Unicellular organisms, like the algae in the picture, are organisms that consist of only one cell. Single-celled organisms are mainly bacterias, archaea, protists and some fungi. Most unicellular organisms are microscopic, but some can be seen with the...

Biology
some living descriptions
Protista-
- unicellular eukaryotes, some multicelled forms
- cell sturcture simple to very complex
- some heterotrophs- protozoans
- some autotrophs- algae
- asexual repro, some both sexual, asexual
- motile, non-motile, sizes- most microscopic but some may be 100m in length
- cell walls
- ex. paramecium, amoeba, euglena, diatoms, volvox, dinoflagellates, plasmodium, trypanosomes.
- multicellular Eukaryotic
- chitin cell walls, hyphae for cell forms, Yeasts are ovoid cells
- heterotrophs (saphrophytes, parasites, mutualistic)
- many species show both sexual and asexual
- organisms range from microscopic to many meters in length
- Ex. morels, corn smut, yeasts, bread mold, mildews
- Plantae-multicellular Eukaryotes
- cellulose cell walls
- photosynthetic autotrophs
- sexual repro
- alternation of generations
- sporophyte
- gamophyte
- can be marine, freshwater, terrestrial etc
- starch as stored glucose
- chloroplasts
- vascular have xylem and phloem
- avascular ex: mosses liver worts
- Chlorophyll A.
- Multicellular Eukaryotes
- no cell wall
- heterotrophs
- typically motile
- zygotes formed
- glycogen
- invertebrates/vertebrates
