The Incredible Tree of Life

Emily Burke

Domain Eukarya

Includes Kingdoms Plantae, Fungi, and Protista

Cells contain a "true" nucleus and specialized organelles in the cytoplasm. They divide using mitosis or meiosis which is characteristic of all life forms except bacteria, blue-green algae, and other primitive microorganisms.

Kingdom Protista

Domain: Eukarya

Kingdom: Protista

Cell Type: Eukeryote

Cell Structure: Cell walls of cellulose and some have chloroplasts

Number of Cells: Most unicellular, some colonial or multicellular

Nutrition: Autotroph or Heterotroph

Examples: Ameoba, Paramecium, Molds, or Giant Kelp

Most live in water. A protist is any organism that is not a plant, animal or fungus. Protista means "the vary first". Protists are classified by: how they obtain nutrition and how they move.

Animal-like Protists: also called protozoa (means “first animal”) – heterotrophs

Plant-like Protists: also called algae – autotrophs

Fungus-like Protists: heterotrophs, decomposers, external digestion

Kingdom Fungi

Domain: Eukarya

Kingdom: Fungi

Cell Type: Eukaryote

Cell Structures: Cell walls of Chitin

Number of Cells: some unicellular, most multicellular

Mode of Nutrition: Heterotroph

Example: Muchrooms or Yeast

The organisms in this kingdom include mushrooms, yeasts, molds, rusts, smuts, puffballs, truffles, morels, and molds. They live in the air, water, land, soil, and on or in plants and animals. Some are microscopic and others cover large plots of land. Mycology is the study of fungi. Fungi appear like plants but are suprisingly closely related to animals. They are not capable of producing their own food, so they recieve their nourishment from other sources.

Domain (Eu)bacteria

Domain: Bacteria

Kingdom: Eubacteria

Cell Type: Prokaryote

Cell Structure: Cell walls with peptidogylcans

Number of Cells: Unicellular

Nutrition: Autotroph or Heterotroph

Example: Strep or E.coli

Bacteria are the most abundant organisms on earth. They replicate FAST.

They use both aerobic and anaerobic respiration. Some eubacteria carry out photosynthesis. Some use carbon dioxide in photosynthesis as plants do, but other eubacteria use other organic compounds as a source of carbon for photosynthesis.

Other eubacteria fix nitrogen as a by-product of their respiration. These eubacteria need an anaerobic environment to survive. Plants provide nodules on their roots for these bacteria that are oxygen free. The plants gain nitrogen and the eubacteria somewhere to live. This is an example of symbiosis: a close mutually dependent relationship between two organisms.

Domain Archaea

Domain: Archaea

Kingdom: Achaebacteria

Cell Type: Prokaryote

Cell Structure: Cell walls without peptidoglycans

Number of Cells: Unicellular

Nutrition: Autotroph or Heterotroph

Example: Methanogens or Halophiles

Archaea are less widespread than Bacteria. Archaea is derived from the Greek word archaios, meaning “ancient” or “primitive”.

Many of them are methanogens which means that to produce energy they use H2 gas to reduce CO2 to methane, which releases energy.

Many Archaebacteria are adapted to extreme environments.

Thermophiles: “heat lovers.” Inhabit hot springs. Tolerate temps from 70 -- >110°C.

Halophiles: “salt lovers.” Require water that is 15-20% salt (seawater only 3% salt).

Archaebacteria more closely related to the Eukarya than are the Eubacteria.

Kingdom Plantae

Domain: Eukaryote

Kingdom: Plantae

Cell Type: Eukaryote

Cell Structures: Cell walls with cellulose; chloroplasts

Number of Cells: Mulitcellular

Mode of Nutrition: Autotroph

Example: Moss, ferns, or flowering plants

This Kingdom includes all types of eukaryotic, multicellular, photosynthetic plants. Most of the organism in this kingdom are autotrophs, which synthesize their own food with the help of solar energy. They are the source of food for all other living things on this planet. Most of the plants are eukaryotic and chlorophyll containing organisms and lack motility. They have the ability to grow by cell division and have both organs and organ systems. Plants reproduce both by sexual and asexual (alternation of generations). Plants develop self defense mechanisms to protect them from being destroyed by animals, fungi and other plants.
