摘要

Mechanical load is 10(3) larger for land-living than for waterliving organisms. As a consequence, antigravitational material in form of compound materials like lignified cell walls in plants and inineralised bones in animals occurs in land-living organisms preferentially. Besides cellulose, pectic substances of plant cell walls seem to function a's antigravitational material in early phases of plant evolution and development. A testable hypothesis including vesicular recycling processes into the tensegrity concept is proposed for both sensing of gravitational force and responding by production of anti gravitational material at the cellular level.
