Have you ever thought that the color of the light can affect the plant growth? I believe that color will affect the plant growth. Light is essential during plant growth and photosynthesis. Light powers and gives energy to the plant. In my project, I will use these following materials: Blue light bulb, red light bulb, white light bulb, three planting pots, soil, and water. I chose this topic because I have wondered if plants can grow without light or if plants can grow with a different color light. Does the color of light affect the plant growth?

What color is the most effective? There are many color that can affect plant growth. Green light is the least effective. Plants are green due to the green pigment in the cells of the plant. Green also has a shorter wavelength. Different colors of light changes what will occur in the plant. Blue light has a shorter wavelength, causing the light to have more energy.

Blue light has a shorter wavelength than green. Blue light is needed at the beginning of plants growth. Blue light ensures healthy roots, strong stems, and healthy leafs. Without blue light, the plant would not be able to come up out of the ground. White and red light are different from blue light.

Some people believe by removing yellow or white light, plants can produce healthier indoor plants than plants grown outdoors. White light has a medium wavelength, so it is in between blue and red light.

Red light is at the very end of the wavelength spectrum. Red has the longest wavelength, causing it not to have a lot of energy. Red light is used during the flowering or blooming process. Vegetables aren’t affected by red lights. It’s best to use red light toward the end of the plant cycle.

How are plants affected by light? All living things need energy to grow. We get energy from food. Plants get energy from light through photosynthesis. Without light, the plant would not have any energy to grow. If plants don’t get enough energy, or light, many things can occur. Stems can become saggy or stretched out, the leafs may turn yellow, the leafs can become small, the leafs or stem can become spiraled, the leafs can also start to get brown at the tips of the lead, and lastly, the lower leafs can dry up and shrink. When plants get enough energy, none of those things will occur and you would get a healthy plant.What is photosynthesis?

Photosynthesis is a process by which plants, algae, and certain bacteria collect sunlight to then become food for the plant to use. During photosynthesis, light energy is absorbed into chlorophyll. The energy allows the creation of sugar by the reaction of water and carbon dioxide. The equation is: 6CO2+6H2O—>C6H12O6 + 6O2, or Carbon dioxide + water —> sugar and oxygen. Sugar, or glucose is made of carbon, hydrogen, and oxygen.

How do plants grow? Plant growth start with a seed. The seed needs food, enough water, and sunlight. When the seeds are planted into the soil, they will first grow roots. The roots will collect water and nutrients from the soil. The nutrients will help the plant grow. The sunlight will provide energy for photosynthesis. Water lets the plants roots grow and stretch out to find more water. The growth is continuous until the plant is fully grown.

What do plants need to grow? Plants need many things to grow. Plants need food, which is sugar or glucose, water, and sunlight. Food gives the plant nutrients and energy to grow. Water also help plant growth. Water moves the nutrients in the plants roots to different parts of the plant. Plants get their energy from sunlight. Without sunlight, a plant would not be able to get energy to grow or produce food. Plants need all these things to survive.

Does the color of light affect the plant growth? Yes, it does. My hypothesis is that blue light will be the most effective. I believe this because plants won’t come up out of the ground if the plant didn’t have blue light, and blue light has shorter wavelengths , than red and white, so blue light will have more energy to give to the plant.
