WebApr 9, 2024 · Photomorphogenesis is the growth and development of plants in response to light. It allows plants to optimize their use of light and space. Photoperiodism is the ability to use light to track time. Plants can tell the time of day and time of year by sensing and using various wavelengths of sunlight. WebWell auxin will move to the shaded side of the plant stem and cause those cells to grow longer, while the cells on the sunny side of the plant stay the same size. That will cause the plant to bend to one side – toward the sun! GIBBERELLIN Gibberellin causes some similar effects in plants as auxin, but it is a very different hormone.

WebIn the coleoptile of canary grass, Charles Darwin noticed phototropism movement (plants bending towards light). He saw that near the tip of the coleoptile, there was an influencer that caused the bending towards the light. The chemical responsible for phototropic movement in the oat coleoptile was later isolated and termed "Auxin" by Frits Went. WebAuxin releases hydrogen ions in the plant cell and shifts towards the darker portion of the stem, leading to a decrease in the plant cell’s pH. The decrease in pH activates the release of an enzyme (expansins). The enzyme expansins will cause swelling in the cell and finally result in the plant’s bending towards the light. Types of Phototropism WebThis emits the perfect light output for encouraging natural growth and prevents plants from bending toward a single light source. The light also works on an 8-hour, 10-hour, 12-hour, or 14-hour light cycle, simulating sunrise, daylight, dusk, and nighttime.
