Oil body

Not to be confused with Elaiosome, a multicellular structure found in seeds.

An oil body is a lipid-containing structure found in plant cells. The term can refer to at least two distinct kinds of structures in different kinds of plants.

Oil bodies in liverworts[edit]

Liverwort oil bodies are structures unique to liverworts that contain isoprenoid essential oils and are surrounded by a single membrane.[1] The size, shape, color, and number of oil bodies per cell is characteristic of certain species and may be used to identify these.

Oil bodies in vascular plants[edit]

Some species of vascular plants also contain intracellular structures called oil bodies. Vascular plant oil bodies consist mainly of triacylglycerols surrounded by a layer consisting of phospholipids and the protein oleosin.[2] These oil bodies occur largely in seeds but also occur in other plant parts, including leaves.[3]
