Parental Note: This experiment can be completed independently by children 8 years of age and older. The plant does not absorb the green light so does not use it to grow. Answer 2: The color or wavelength of light does affect photosynthesis, which is how plants can basically create their own food.
Keep a record of the plants’ growth every day, taking measurements and noting color when the plants begin to germinate.
Plants are sensitive to the color red in the light spectrum, a sensitivity that arises from the plant having what is called a red light photoreceptor. The project may require some support to track plant growth and take anecdotal notes over the span of two weeks. For optimal growth, most plants should be placed directly beneath the bulbs, at a distance of about 6 inches. Grow lights emit enough red light to encourage bloom in flowering plants. Some plants need more hours of light than others, but most will thrive on 12 hours. You could compare phytochrome with an eye that only senses red light. If plants do not receive enough light, they will not grow at their maximum rate or reach their maximum potential, regardless of how much of any other variable – water, growth medium or fertiliser – they receive.
Plants first need sufficient exposure to fluorescent light. 679 Words 3 Pages. Essentially, the reason why plants are green is they are absorbing the other wavelengths of light … And while soil nutrients help to fortify plant structures, light is an essential component in producing actual food for the plant. Plant growth processes involve the use of light, carbon dioxide and water to manufacture food for the plant’s use, according to the Texas A&M University Agricultural Extension Service. are key when jotting down information in the journal or log book. March 25, 2019. Light is the most important variable influencing plant growth. Explanation: Plants get their energy from light, but different colors of … Measuring Plant Growth with Sunlight. Descriptions of the plants fullness, leaf size, etc.

Research; Effects of Colored Light on Plants; Effects of Colored Light on Plants . Plants are dependent on light to generate food, induce the growing cycle and allow for healthy development. The plants with the blue color of light seem to grow the tallest, with 0.013 cm taller than red. Blue light will allow the plant to grow leaves and other vegetation and red light with blue allows the plant to grow flowers. Light directly influences plant growth and flowering by inducing photosynthesis and feeding plants energy. The receptor is a blue-green pigment called a phytochrome present in the cells of a plant.
