Definission: A shape for a biological structure that approximates an ellipsoid. (eg: for a cell, see Table 1, Olenina, I., Hajdu, S., Edler, L., Andersson, A., Wasmund, N., Busch, S., Göbel, J., Gromisz, S., Huseby, S., Huttunen, M., Jaanus, A., Kokkonen, P., Ledaine, I. and Niemkiewicz, E. 2006.

Definission: A spheroid quality inhering in a bearer by virtue of the bearer's resembling a ball (a sphere whose equatorial diameter is equal to the polar diameter).
Definission: Seed-bearing organ on gymnosperm plants. A type of fruit, usually woody, ovoid to globular, including scales, bracts, or bracteoles arranged around a central axis, especially in conifers and cycads.
Definission: an inflorescence with a monopodial growth habit, composed at flowering stage of indeterminate, first order inflorescence axes and sessile, unisexual flowers each subtended by conspicuous inflorescence bracts
Definission: a plant that produces wood as its structural tissue. Wood is a structural cellular adaptation that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants. Wood is usually primarily composed of xylem cells with cell walls made of cellulose and lignin
