What are prokaryotic cells and why are they important?

Answer 1

They live in our gut and make vitamin K, as well as the "beneficial" bacteria etc out competing the more dangerous ones. They help with other aspects of digestion, though sometimes that may make us a little gassy as they ferment small quantities of undigested or partially-digested food.

A large portion of the oxygen we breathe comes from prokaryotes in the ocean completing photosynthesis, using the CO2 dissolved in the water, and making more "space" (preventing complete saturation of the oceans with carbon dioxide) for CO2 from the atmosphere to be absorbed by the ocean.

Answer 2

Prokaryotic cells are bacterial cells. they are a lot smaller then a normal cell and are in a capsule form so getting in and out of foreign cells is simple for them. They have no membrane bound nucleus or organelle and they have naked DNA. They reproduce through Bacterial Conjugation. where two bacteria exchange genetic material through a a tube called a sex pilus. i hope this helped :)

Answer 3

Prokaryotic cells are simpler then eukaryotic cells. They are usually much smaller, and have less organelles. They lack membrane-bound organelles, such as the nucleus and instead keeps the genetic information concentrated into a small area called a nucleoid.

Answer 4

There are many importances of prokaryotes, more commonly bacterias. In addition to helping the body with the production of vitamin K, bacterias are also responsible for the nitrogen cycle, turning the unusable N2 into forms which can be used by animals.

Answer 5

provide nutrients

break down organic matter

Answer 6

Prokaryotes provide an essentially ecological service in liberating the nutrients needed for photosynthesis and thus for the sustenance of life.

Answer 7

Prokaryotic cells are the 'ancient/primitive' cells. They are the cells of bacteria.

Answer 8

yup
