Description

The single trichome is unbranched and covered with a firm, thin, hyaline to yellow-brown homogeneous or lamellated sheath. This sheath generally projects some distance beyond the trichome. The trichome is cylindrical, with rounded apices and can be either straight, flexed or twisted with regular spirals. The contents of the cell are homogeneous, granulose and with numerous pseudovacuoles.

General Biology

This is a freshwater as well as a saltwater organism, sometimes occurring as subaerial,

Life Cycle

All cells have the ability to divide, thus increasing in the size of the organism. Fragmentation occurs when one or more cells along the trichome die, resulting in the breaking up of the trichome into a number of pieces.

Human Uses

Extracts of Lyngbya have been found to have anti-lymphocytic leukemia properties in mice (Mynderse et al., 1977).
