What is the smallest living organism? How is similar to, and different from a large organism (such as a human)

Question

Please help me.

Answer 1

The smallest organisms would be bacteria. Bacteria differ
in size but the lower limit of the length of the
bacterial body would roughly be 1 micrometer (a
thousand's of a milimeter).
what is an organism? What are the requirments to be an
organism? An organism is a living thing
that is able to live independent of other organisms,
that has a metabolism, and that reproduces with
offspring identical to the parent. That is how they are simular to humans and differant because it does'nt have a brain to reason with. Hope this helps you dear..........Flo

Answer 2

a paramecium is a single celled organism, extremely small. Compared to a human it feeds, digests and excretes. However, this process is doen in a completely different way. The one celled organism also maintains homeonstasis in similar ways by regulating the chemicals that enter and exit the cell in a similar way that we do.

hope this helps :)

Answer 3

Organisms from the domains "Bacteria" and "Archaea" are uni-cellular and are prokaryotic (don't have a nucleus). You will find your smallest organism from there.

Humans belong to the domain "Eukarya"; we have many cells and we are Eukaryotic (cells with a nucleus).
