Nutation (botany) flowers to open or close by movements which resemble the simple nutation of dorsiventral organs. Thus, the tulip, crocus, and other vernal flowers are very sensitive to changes in temperature. The crocus can perceive a change of 0.5°C (0.9°F), and will respond to a change of 20°C (36°F) in two minutes. Nutation (botany) Nutation is the bending movements executed by some plant organs, such as stems, leaves, roots, etc., by which the part is inclined successively in various directions. Nutations are due to the unequal rate of growth of different sides of the organ, an inequality which, so far as
Offset (botany) Offset (botany) In botany and horticulture, an offset is a small, virtually complete daughter plant that has been naturally and asexually produced on the mother plant. They are clones, meaning that they are genetically identical to the mother plant. They divide mitotically. In the plant nursery business and gardens, they are detached and grown on in order to produce new plants. This is a cheap and simple process for those plants that readily produce offsets as it does not usually require specialist materials and equipment. Offsets form when meristem regions of plants, such as axillary buds or homologous structures differentiate
