1. Angiospermae
A major division of the plant kingdom, commonly called flowering plants as their reproductive organs are in flowers, having seeds which develop in a closed ovary made of carpel s, a very reduced gametophyte , and endosperm develop from a triple fusion nucleus.

2. Animalia
Animal kingdom. Multicellular eukaryotic group characterized by heterotrophic nutritional mode, usually organ and tissue development, and motility sometime during the organism's life history.

3. Arachnid
An organism of the class Arachnida in the kingdom Animalia. For example, a spider.

4. Archae (Archaebacteria)
This is a super-classification of odd bacteria that are neither prokaryote s nor eukaryote s; some scientists believe they represent a separate kingdom. The primary genus is Archaebacteria, whose members fall in three categories: microbes that can live in extremely salty environments (halophiles), microbes that produce methane (methanogens), and microbes that can live in extremely hot environments (thermophiles). All are of interest to biotechnologists because they have unique biochemical features (e.g., the enzyme s of the theromophiles are extremely stable at high temperatures).

5. Archaea
Proposed, but not widely accepted, sixth taxonomic kingdom that would include the archaebacteria.

6. Archaebacteria
Ancient (over 3.5 billion years old) group of prokaryotes; some biologists want to place this group into a separate kingdom, the Archaea. Most currently place it within the kingdom Monera .

7. Bacteria (Eubacteria)
A super-classification (above kingdom level) of all prokaryote s; excludes Archaebacteria .

8. Brassica (Brassicaceae, Cruciferae)
A genus of plants belonging to the mustard family Brassicaceae. The whole family includes a total of 376 different genera and 3,200 different species . The family is also known as "Cruciferae" because the four petaled flowers of these plants look like crosses. The plants are distributed worldwide and have annual (living one year), biennial (living two years) and perennial (living many years) members. Member species of genus Brassica include Brassica napus which produces rapeseed or canola oil; Brassica nigra which produces yellow mustard; Brassica oleracea whose subspecies and strains include kale and collard greens (B. oleracea acephala), broccoli (B. oleracea botrytis), cauliflower (B. oleracea cauliflora), head cabbage (B. oleracea capitata), brussel sprouts (B. oleracea gemmifera), and kohlrabi (B. oleracea gongycoides); and Brassica rapa, whose subspecies include pak choi (B. rapa chinensis), Chinese cabbage (B. rapa pekinensis), and turnip (B. rapa rapifera). Also, one subspecies of B. rapa is used as a model organism to study genetics , molecular biology , plant breeding, cell biology , and physiology ; it is called the "rapid cycling" Brassica or RCBr or the Wisconsin Fast PlantTM , and was developed specifically for scientific study. Additionally, the radish Raphanus sativus is a member of the Brassicaceae family. The full taxonom ic classification is kingdom Plantae, division Tracheophyta, subdivision Spermatophyta, class Angiospermae, subclass Dicotyledeonae, order Papaverales, family Brassicaceae.

9. Caenorhabiditis elegans
This is a free-living (non parasitic) species of nematode which makes a good model organism for biological study because it has a small genome of only six chromosome s. It also has a short generation time of about three days (at room temperature), and is easy to grow at high densities (up to 10,000 worms on one Petri dish). C. elegans has been thoroughly studied by geneticist s, developmental biologist s and neurologists. The worms can be used to study genetic manipulation , gene therapy , and the molecular basis of differentiation during development. Much of the world's knowledge about aging, inheritance, and the factors which control gene expression during development comes from studying this and other nematodes. The full taxonomic classification of C. elegans is: kingdom Animalia, phylum Nematoda, class Secernentea, subclass Rhabditia, order Rhabditida, family Rhabditidae.

10. Division
* The act of dividing. * The second highest taxonomic classification for the kingdom s Plantae (plants) and Fungi, between kingdom level and class level.
