Use the tree to determine which statements regarding the origins of these organelles are true. In some instances, plants are also deliberately infected with relatively harmless viruses like the Honeysuckle Yellow Vein virus (HYVV) and the Abutilon Mosaic virus. (1), Variegation results from a defect that makes chloroplast development unstable, since at least part of the tissues gives rise to normal chloroplasts.. There are three types of natural variegation depending on whether the genetic mutation only happens to some parts of the plant or the entire plant. Other plants have tiny hairs on the leaves. If the mutation happens to only some cells of the plant with regular plant cells alongside cells that are unable to synthesize chlorophyll, the chimeral variegation is unstable and irregular. secondary endosymbiosis, a process in which a cell engulfs a eukaryotic cell, such as green algae, that already contains chloroplasts.
