Bacteria use energy, reproduce, have dna, respond to change,etc
the virus can only reproduce and it only has genetic material
<span>The structure of a paramecium that holds a "reserve copy" of all the cell's genes is the micro nucleus.
</span>The micro nucelus is one of the <span>two kinds of </span>nuclei the paramecium has. The other is the<span> large ellipsoidal </span>nucleus<span> called a macronucleus. Every paramecium must have at least one small </span>nucleus<span> called a </span>micronucleus. The micronucleus is a storage site for the germline genetic material of the organism.
They are all living, they grow, reproduce, excrete, respire and require nutrition. They all differ, the human, oak tree, sea weed and mushroom are multicellular( prokaryotes), and the rest are Unicellular( Eukaryotes). The sea weed& most bacterium produce their own food while the rest need to feed.
