what is the main defrance between yeast and Bacteria.?

Answer 1

Yeasts are single-celled (unicellular) fungi, a few species of which are commonly used to leaven bread, ferment alcoholic beverages, and even drive experimental fuel cells. Most yeasts belong to the division Ascomycota, though some are Basidiomycota. A few yeasts, such as Candida albicans, can cause infection in humans (Candidiasis). More than one thousand species of yeasts have been described. The most commonly used yeast is Saccharomyces cerevisiae, which was domesticated for wine, bread, and beer production thousands of years ago. Yeast, paricularly baker's yeast, may have an unpleasant smell.


Bacteria (singular: bacterium) are a major group of living organisms. The term "bacteria" has variously applied to all prokaryotes or to a major group of them, otherwise called the eubacteria, depending on ideas about their relationships. Here, bacteria is used specifically to refer to the eubacteria. Another major group of bacteria (used in the broadest, non-taxonomic sense) are the Archaea. The study of bacteria is known as bacteriology, a subfield of microbiology.

Answer 2

BOTH bacteria and yeasts are unicellular (single celled)
Bacteria are NOT animals
Bacteria are no longer considered MONERANS
Bacteria are not the only "GERMS" (although that term is no longer used, it could refer to any small pathogenic organism, not just bacteria)

the main difference is that bacteria are prokaryotes "first seed" (which do NOT have membrane bound organelles, this includes a nucleus, but also mitochondria, ER, Golgi bodies, chloroplasts etc)
and yeasts are eukaryotes "true seed" (which DO have membrane bound organelles)

then there are all the other differences as well, such as (but not imited to...)
size
shape of DNA
amount of DNA (# of chromosomes)
size and # of subunits of ribosomes
structure of cell wall (peptidoglycan vs chitin)
how they make energy
where they are found

etc

Answer 3

Many of us know bacteria only as “germs,” invisible creatures that can invade our bodies and make us sick.

Some microbes live on our skin and protect us from many harmful agents. The drier areas, like the back, have few microbes; moist areas, such as under the arm, have many more.
Few know that many bacteria not only coexist with us all the time, but help us do an amazing array of useful things like make vitamins, break down some garbage, and even maintain our atmosphere.
Bacteria can be found virtually everywhere. They are in the air, the soil, and water, and in and on plants and animals, including us.
Fungi straddle the realms of microbiology and macrobiology.

They range in size from the single-celled organism we know as yeast to the largest known living organism on Earth — a 3.5-mile-wide mushroom.
It started out 2,400 years ago as a single spore invisible to the naked eye, then grew to gargantuan proportions by intertwining threads of cells called hyphae.

Under a microscope, hyphae look like a tangled mass of threads or tiny plant roots. This tangled mass is called the fungal mycelium, and is the part of the famous honey mushroom that spreads for miles underground.

Answer 4

The main difference between yeast and bacteria is the presence of organelles. In an evolutionary leap forward, yeast are the first organism that we know about that contains small intracellular bodies that have specialized function(s) (i.e. the nucleus, golgi, mitochondria, ER, etc.). This is the defining characteristic of eukaryotic cells, and serves as a branch point for evolution of single-celled (and eventually multicellular) organisms.

Answer 5

Yeast has a nuclear membrane that houses their DNA (and some RNA) and bacteria does not.
Yeast has multiple chromosomes (10-20), whereas bacteria have one or two.
Yeast has very different cell wall structures than bacteria and plants.

Answer 7

Bacteria is a one-celled animal. A very, very basic form of life. Yeast is a mould, comprised of many cells.

Answer 8

both bacteria and yeast are unicellular organisms.

however, bacteria are prokaryotic, that is, they do not have a nuclear region or nucleus. while yeast, is a eukaryote, that is, with a nucleus and yeast (eg. Saccharomyces and Schizosaccharomyces) are of the kingdom fungi.

Answer 10

bacteria is a single-celled animal whereas yeast is a organism with many cells.
