geotropism การใช้

• Auxin participates in phototropism, geotropism, hydrotropism and other developmental changes.
• Geotropism allows the roots of a plant to determine the direction of gravity and grow downwards.
• The official designation was G-009 : Purdue University-Geotropism, Fluid Dynamics and Nuclear Particle Velocity.
• Well, Ms . Bowers, neither are a lot of other words, either, including, but not limited to, " geotropism " and " parenchyma ."
• Darwin also drew attention to the similarities between animals and plants, e . g ., sensitivity to touch ( thigmotropism ), light sensitivity ( phototropism ), and gravity ( geotropism ).
• He earlier research largely dealt with physiology of plants; working with subjects such as : growth rhythm, nyctinasty, geotropism, leaf positioning, electrical potential differences on cell walls, et al.
• She attended Brighton High School and studied botany Royal Holloway, University of London, graduating with 2nd Class Honours in 1899 . In 1912 she became a part-time Reader in Botany at geotropism ).
• Among these are his investigation of the periodicity of growth in length, in connection with which he devised the self-registering auxanometer, by which he established the retarding influence of the highly refrangible rays of the spectrum on the rate of growth; his researches on heliotropism and geotropism, in which he introduced the clinostat; his work on the structure and the arrangement of cells in growing-points; the elaborate experimental evidence upon which he based his " imbibition-theory " of the transpiration-current; his exhaustive study of the assimilatory activity of the green leaf; and other papers of interest.
