Chloroplasts are one of many types of organelles in the plant cell. They are considered to have evolved from endosymbiotic cyanobacteria. Mitochondria are thought to have come from a similar endosymbiosis event, where an aerobic prokaryote was engulfed. This origin of chloroplasts was first suggested by the … See more A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and … See more Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA (cpDNA) was identified biochemically in 1959, and … See more Distribution in a plant Not all cells in a multicellular plant contain chloroplasts. All green parts of a plant contain … See more Chloroplasts are a special type of a plant cell organelle called a plastid, though the two terms are sometimes used interchangeably. There are many other types of plastids, which carry out various functions. All chloroplasts in a plant are descended from … See more The first definitive description of a chloroplast (Chlorophyllkörnen, "grain of chlorophyll") was given by Hugo von Mohl in 1837 as discrete bodies within the green plant cell. In 1883, See more In land plants, chloroplasts are generally lens-shaped, 3–10 μm in diameter and 1–3 μm thick. Corn seedling chloroplasts are ≈20 µm in volume. Greater diversity in chloroplast shapes … See more Guard cell chloroplasts Unlike most epidermal cells, the guard cells of plant stomata contain relatively well-developed chloroplasts. However, exactly what they do is … See more WebDuring the evolution, most of the cyanobacterial genes were lost and many of them were transferred into the nuclear genome. A majority of the chloroplast proteins are nuclear-encoded with an N-terminal transit peptide, which helps the protein to be targeted into chloroplasts. Even though, chloroplasts have their own genetic system, which works ...
WebSince the discovery of chloroplasts and mitochondria as eukaryotic cell organelles in the last century until the late seventies of the twentieth century the evolution of eukaryotic cells was generally understood as an autogenous or endogenous process (Allsopp 1969; Kirk 1971; Raff and Mahler 1972; Bogorad et al. 1973; Parthier 1974, for review: Gray and Doolittle … WebApr 10, 2024 · Moreover, the evolution patterns of chloroplast genes in Dendrobium among three photosynthetic pathways were also diversified. Considering the diversified genome structure variations and the evolution patterns of protein-coding genes among Dendrobium species, we proposed that the evolution of the chloroplast genomes was disproportional …
