Sessile animals can move via external forces (such as water currents), but are usually permanently attached to something. Organisms such as corals lay down their own substrate from which they grow. Other animals organisms grow from a solid object, such as a rock, a dead tree trunk, or a human-made object such as a buoy or ship's hull.
In materials science, the sessile drop technique is a method used for the characterization of solid surface energies, and in some cases, aspects of liquid surface energies. [1] The main premise of the method is that by placing a droplet of liquid with a known surface energy and contact angle , the surface energy of the solid substrate can be ...
All cells can be considered motile for having the ability to divide into two new daughter cells. [1] Motility is the ability of an organism to move independently using metabolic energy. This biological concept encompasses movement at various levels, from whole organisms to cells and subcellular components.
Sessility, or sessile, may refer to: Sessility (motility) , organisms which are not able to move about Sessility (botany) , flowers or leaves that grow directly from the stem or peduncle of a plant
Cloth, treated to be hydrophobic, shows a high contact angle. The theoretical description of contact angle arises from the consideration of a thermodynamic equilibrium between the three phases: the liquid phase (L), the solid phase (S), and the gas or vapor phase (G) (which could be a mixture of ambient atmosphere and an equilibrium concentration of the liquid vapor).
During its motile form, the free-swimming telotroch appears as a long cylinder, moving quickly and erratically. Stalk materials are secreted in order for the cell to become sessile. Stalk precursors are held in dense granules at the aboral or basal end of the telotroch, which are released as a liquid by exocytosis. That liquid solidifies to ...
Marine larval ecology is the study of the factors influencing dispersing larvae, which many marine invertebrates and fishes have. Marine animals with a larva typically release many larvae into the water column, where the larvae develop before metamorphosing into adults.
As with all Cnidarians, these organisms have a complex life cycle including a motile planktonic phase and a later characteristic sessile phase. Hexacorallia also include the significant extinct order of rugose corals .
