A: Cytoplasm has many functions in both prokaryotic and eukaryotic cells, including aiding in the movement of cellular materials and transporting the genetic material and products of cellular respiration. It also acts as a liquid medium to suspend organelles and helps cells expand during reproduction.
Cytoplasm-The cytoplasm, or protoplasm, of bacterial cells is where the functions for cell growth, metabolism, and replication are carried out. It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm.
