Kranz anatomy (rings of cells) shown C 4 plants often possess a characteristic leaf anatomy called kranz anatomy , from the German word for wreath . Their vascular bundles are surrounded by two rings of cells; the inner ring, called bundle sheath cells , contains starch -rich chloroplasts lacking grana , which differ from those in mesophyll ...
Among the species of Suaedoideae, there are nearly equal numbers of C 3-plants and C 4-plants.During the evolution of the subfamily, the C 4-photosynthesis pathway seems to have been derived from four independent origins: two times with Kranz C 4 anatomy in Suaeda section Salsina and Suaeda section Schoberia.
Leaves may also be whorled if several leaves arise, or appear to arise, from the same level (at the same node) on a stem. Veronicastrum virginicum has whorls of leaves separated by long internodes. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same node), on opposite sides of the stem. An opposite ...
English: The C4 pathway contains a special structure in the leaves known as Kranz anatomy. There exists a layer of mesophyll cells that contain small chloroplasts encircling bundle sheath cells that have large chloroplasts necessary for the Calvin cycle.

Many species have thick, succulent leaves, ... uses a particular type of C 4 photosynthesis without the typical "Kranz" leaf anatomy. [7] [8] [9] Uses.
Kranz leaf anatomy in plants which perform C 4 carbon fixation; Succulent leaves store water and organic acids for use in CAM photosynthesis. Aromatic oils, poisons or pheromones produced by leaf borne glands deter herbivores (e.g. eucalypts). Inclusions of crystalline minerals deter herbivores (e.g. silica phytoliths in grasses, raphides in ...
Bienertia sinuspersici conducts C 4 photosynthesis, but lacks the two cell types, bundle sheath and mesophyll cells, that are typical of Kranz anatomy in most C 4 plants. Bienertia sinuspersici and three other former chenopods ( Suaeda aralocaspica , Bienertia cycloptera , and Bienertia kavirense ) instead conduct single-celled C 4 ...
