plasmalemma /ˈplazməˌlɛmə /noun BiologyA plasma membrane which bounds a cell, especially one immediately within the wall of a plant cell.It is, therefore, most unfortunate that little is known of them except that they appear to be gated by tension and link the cell wall to the plasmalemma and possibly the cytoskeleton....- A mechanosensitive Ca 2 + channel is shown linking the cell wall to the plasmalemma so that relative movement between them, or between the former and the cytoskeleton, could open the channel.
- Folding of the plasmalemma and the formation of multiple small vesicles between the cell wall and the plasmalemma were observed.
Derivativesplasmalemmal adjective ...- Caveolins are the main structural proteins of glycolipid/cholesterol-rich plasmalemmal invaginations, termed caveolae.
- The undulating plasmalemmal invaginations have been reported to be unique to brown adipose tissue and hibernomas.
- Ultrastructural examination of the tumor in case 2 revealed pleomorphic mitochondria with dense matrices and transverse lamellar cristae, micropinocytotic vesicles, and periodic short plasmalemmal densities.
Origin1920s: from plasma + Greek lemma 'rind'. |
