How plants respond to gravity
NettetThe term geotropism (sometimes called gravitropism) describes how plants respond to gravity. Roots are termed positively geotropic; that is, they grow toward the direction of the pull of gravity. Shoots are … Gravitropism is an integral part of plant growth, orienting its position to maximize contact with sunlight, as well as ensuring that the roots are growing in the correct direction. Growth due to gravitropism is mediated by changes in concentration of the plant hormone auxin within plant cells. As plants mature, gravitropism continues to guide growth and development al… Gravitropism is an integral part of plant growth, orienting its position to maximize contact with sunlight, as well as ensuring that the roots are growing in the correct direction.
