Effect Of Uv Light On Plant Growth Experiment

Ultraviolet light is used to kill bacteria and other microscopic life forms.

Effect of uv light on plant growth experiment. There were no other differences between the two groups of plants except the height. Develop a hypothesis to predict how increased ultraviolet radiation might affect lettuce plant growth. White light 3 plants have light receptors that detect visible light and generate a response. Is uv b harmful to humans.

Its deadly effect is not limited to microscopic organisms though. Ultraviolet light of the b variety encourages plants to produce their own natural sunscreen. Based on the bswf obtained in the study the integrated uv light effect on the bryophyte fluorescence increased only 5 under the same scenario of 16 reduction of stratospheric ozone while it increased 20 on growth of higher plants 43 on commission internationale de l éclairage cie erythemal dose and 95 on dna damage. This process creates a sugar called glucose and also produces oxygen.

Alternately grow the plants from seed. Likewise exposure for a long time to this type of light will damage the plants that you are growing a study conducted demonstrated that plants raised without exposure to uv light exhibited enhanced growth. Uv light s effects on plant and animal life finally uv light is known to have some effects on animal life as well. The light energy from the sun then triggers a chemical reaction that breaks down the carbon dioxide and water molecules.

Concomitantly the amounts of solar uv b radiation reaching the earth s surface is increasing. The glucose is then broken down by organelles called chloroplast and provide the energy needed to grow and repair plants. In the end the uv light plants had grown taller than the sunlight plants. Purchase six lettuce plant seedlings from a plant nursery or other source.

Ultraviolet 20nm to 380 nm being exposed to uv light for a long period of time has harmful effects on humans. Plants which use sunlight for photosynthesis and are unable to avoid exposure to enhanced levels of uv b radiation are at risk. Blue light photoreceptors absorb wavelengths of blue light and trigger a number of reactions in plants. Uv light can alter the composition of materials and conditions needed for photosynthesis the process plants used to grow.

These sunscreens vary from one species to another but include trichome terpene and color development. Light is made up of particles of energy known as photons. Through experimentation scientists have concluded that red light and blue light have the greatest effects on plant growth. The uv b spectrum also offers a bit of natural protection against fungal infection and unwanted pests.
