Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

Pinus merkusii is closely related to the Tenasserim pine (P. latteri), which occurs farther north in southeast Asia from Myanmar to Vietnam; some botanists treat the two as conspecific (under the name P. merkusii, which was described first), but P. latteri differs in longer (18–27 cm or 7– 10 + 1 ⁄ 2 in) and stouter (over 1 mm thick) leaves and larger cones with thicker scales, the cones ...
