If you have a plant experiencing phototropism in a window, try turning the plant in the opposite direction, so that the plant is bending away from the light. It takes only about eight hours for the plant to turn back toward the light. Some plants grow away from light, a phenomenon called...
Hydrotropism (hydro- "water"; tropism "involuntary orientation by an organism, that involvesturning or curving asa positive or negative response to a stimulus") is a plant's growth response in which the direction of growth is determined by a stimulus or gradient in water concentration. What is ...
A radish is what part of a plant? Which color of light is the best stimulus for phototropism seen in stems? Explain. What technique was used to separate the leaf pigments? What influences the plant development? Which hormone stimulates the plants to grow in a manner that the plant appears ...
How can dormancy in seed be broken? Seed: The seed of the plant is the main reproductive unit that allows the growth of another plant under the same species that allows the continuation of the organism. The seeds would be planted in the soil, where it would receive ...
The cellular presence of an endogenous or exogenous (e.g., synthetic) auxin is perceived by the TRANSPORT INHIBITOR RESPONSE1/AUXIN SIGNALING F-BOX (TIR1/AFB) signalling pathway, and triggers the expression of the target genes, which induce biological responses to the received stimulus. The ...
Synthesis or changes in the concentration of these phytohormones transduce the perception of environmental stimulus (i.e., radiation, photoperiod, temperature, gravity or stresses as cold, heat, drought or flooding). However, which plant hormones will be triggered will depend on the plant ...
