Eukaryote Vs. Prokaryote

• Eukarya includes multicellular (us and all other animals, plants, fungi, and some single-celled, or uni-cellular protists).
• all Eukarya are organisms whose cells have nuclei to enclose their DNA apart from the rest of the cell.
• Eukaryotic cells contain membrane-bound organelles that perform specific functions within the cell.
• The 4 kingdoms of the domain Eukarya are: Animalia, Plantae, Protista, and Fungi

Eukarya

• Bacteria are prokaryotes, meaning they are microscopic unicellular organisms that do NOT have a nucleus or organelles (except for ribosomes), and DNA floats freely within the cell.
• Bacteria species are very diverse and include many pathogens (disease-causing bacteria), probiotics (beneficial bacteria), and cyanobacteria.
• Exs of bacteria are: E. coli, Salmonella, Streptococcus

Bacteria - Eubacteria "True Bacteria"

• Like Bacteria, Archaea are also prokaryotes, and lack a nucleus, are uni-cellular, but have a genome that is very different from bacteria.
• They are more primitive than Bacteria. Many Archaea are extremophiles that live in harsh environments, such as areas with high volcanic activity.
• 3 types of Archaean bacteria- thermophiles, halophiles, and methanogens.
• Thermophiles- heat loving and live in extreme environments like hydrothermal vents and geysers.
• Halophiles- salt loving and live in areas with high salt content (ex: dead sea)
• Methanogens- methane producing, and are found in swampy areas, lanndfills, and in the stomachs of some organisms.

Animals are multicellular organisms with eukaryotic cells. This kingdom includes elephants, grasshoppers, dogs, earthworms, octopi, and humans. The animal kingdom is the largest, with over 1 million known species. Animals are heterotrophs, which means they must find and ingest their own food.

Kingdom:Animalia Domain: Eukarya

Kingdom:Plantae Domain: Eukarya

Back

Plants are also multicellular and eukaryotic, but they are autotrophs, which means they make their own food. They use sunlight, air, and water to make sugars and oxygen in the process of photosynthesis.

Kingdom:Protista Domain: Eukarya

Back

Protists are a very diverse kingdom, full of organisms that don't really fit anywhere else. Some protists are animal-like, some are plant-like, and some are fungus-like. Protists are mostly unicellular, but not always. Some are heterotrophs, and some are autotrophs. Some have cell walls, while some do not. Protists are mostly harmless to humans, but some protist diseases can be carried by mosquitoes, flies, or water. Some of the better-known protists are amoeba and algae. Most protists are microbes, which cannot be seen without a microscope.

• Bacteria (or eubacteria) are also unicellular prokaryotes, but their DNA structure is different from archaea.
• They are microbes or microorganisms, meaning they are so small they can only be seen with a powerful microscope. One pinch of dirt, or one drop of water, contains millions of bacteria.
• They reproduce by splitting themselves in two, and they come in many shapes: spirals, spheres, and rods.
• Bacteria are found everywhere - soil, air, water, and on and in plants and animals. In fact, in your own body, there are more bacteria than human cells! There are many different kinds of bacteria. Some live inside your body that can make you sick! Other bacteria live in your digestive system and help keep you healthy. Some bacteria live in the soil and decompose dead plants or animals. Some bacteria live in food and help to make yogurt, cheese, and pickles.

Kingdom:Fungi Domain: Eukarya

Back

Fungi is the kingdom that includes mushrooms, yeasts, molds, and mildew. They are eukaryotic and mostly multicellular. Like plants, they have cell walls, but unlike plants, they do not make their own food. They have to absorb nutrients for energy. Fungi are important in many ways: they are decomposers that help to recycle nutrients in ecosystems. Some important antibiotic medicines, such as penicillin, come from fungi. Yeast is an organism that makes dough rise into delicious loaves of bread. Some fungi, like mushrooms, are tasty to eat. However, certain kinds of fungus can cause diseases in plants and animals. Fungi range in size from too small to be seen (microscopic) to the largest organism on Earth: a fungus in Oregon that covers more than 3 miles!

Back

Archaea are prokaryotes, meaning that they are single-celled organisms that do not have a nucleus. They are said to be "extremophiles," meaning that they live in harsh, extreme environments where other organisms could not survive, such as hot springs, deep ocean volcanic vents, sewage treatment plants, and the insides of some animals. They can be found in boiling water, very salty water, and environments with lots of acid or no oxygen. Archaea are pretty tough little creatures!
