Class Act
This is the highest level of classification in the current system.
Domain
Bacteria belong to this domain of life.
Bacteria
Organisms composed of cells that have a visible nucleus
Eukaryotes
A group of organisms that can mate with one another and produce fertile offspring
Species
Father of the Ladder of Life
Aristotle
In the classification hierarchy, this rank comes after Kingdom.
Phylum
Bacteria are this type of organism, meaning they have no nucleus.
Prokaryotic
This cellular structure, found in eukaryotic cells, is responsible for producing energy.
Mitochondrion
Non-green organisms that reproduce from spores and absorb their food.
Fungi
The lowest rung
Non-living things
This is the specific level of classification that groups organisms capable of interbreeding and producing fertile offspring.
Species
Bacteria reproduce asexually by this process, where one cell divides into two identical cells.
Binary Fission
Eukarya is divided into these four major kingdoms.
Protista, Fungi, Plantae, and Animalia
An organism that has a nucleus but is not an animal, plant or fungus
Protist
You can't have a backbone to reside on this rung.
Second Rung
Organisms in this classification group share similar physical traits but are divided into different species.
Genus
True or False: Bacteria are useful organisms because they decompose dead materials and help recycle nutrients.
True
Eukaryotic cells have membrane-bound structures called these.
Organelles
An organism formed by a fungus and an algae or cyanobacterium
Lichen
Top rung residents
Mammals
One type of organism that is not classified into one of the kingdoms
Virus
Sometimes called blue-green algae
Cyanobacteria
The domain Eukarya includes both unicellular and this type of organism.
Multicellular Organisms
Consisting of two names
