Bacteria: Bacteria can be prokaryotic (don't have a membrane-bound nucleus) or eukaryotic (have a membrane-bound nucleus), but all bacteria have a cell wall, a cytoplasm, and a cell membrane.Bacteria reproduces through a process called binary fission. Amoebae do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms. When food enters the amoeba, it digests the food particle with the help of certain enzymes and uses up the important nutritive portion whereas the waste products are expelled out through the cell wall of the amoeba.
