    clone

    In microbiology, a colony of cells all descended from a single ancestral cell and therefore genetically homogeneous; in molecular biology, an exact replica of a DNA fragment; cloning is the act of preparation and propagation of a genetically defined cell or a DNA fragment.

    protoplast

    A plant cell that has been stripped of its cell wall so as to be limited only by its plasma membrane. (see also spheroplast)

    explant

    A small sample of living tissue, often consisting of different tissue types, that can be sustained in a relatively differentiated state under cell culture conditions. (see also cell culture)

    organelle

    Inclusion in the cell cytoplasm that can be membrane-limited (e.g. chloroplast, mitochondrion, endoplasmic reticulum, Golgi apparatus) or non-membrane-limited (e.g. cytoskeletal element, ribosome, nucleosome).
