Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However‚ after reaching an intensity of 10‚000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may‚ in fact‚ slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100‚000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed

Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked phosphorus

Light pollution Light pollution‚ also known as photo pollution or luminous pollution‚ is excessive artificial light. This phenomenon is pronounced around urban centers‚ where city lights diminish the view of stars and planets. In addition to brightened skies around cities‚ light pollution also refers to any outdoor light that creates glare and interferes with the natural night environment. Cause Light pollution results from outdoor lights aimed

ABSTRACT: By exposing Brassica rapa seedlings to UV-C light‚ the effect of the growth and development of Brassica rapa seedlings was tested. The experimental group of Brassica rapa seedlings was exposed to 254 nm UV-C light for thirty seconds after one week of growth. Throughout the duration of one month‚ the height‚ number of leaves and stem diameter were measured sporadically. After one month‚ the biomass of the seedlings was recorded. A starch analysis test was also performed. According to the

Wavelength on Raphanus Sativus Abstract: Light from the Sun is a full spectrum of different wavelengths of light. Scientists refer to this light as “white light”. When the wavelength of visible light changes‚ so does the color seen by the eye. The shortest wavelengths visible to the human eye are violet (400 nanometers). The longest wavelengths visible the human eye are red (700 nanometers). Each plant is affected differently by the changing wavelengths of light. The purpose of this experiment is to

Electromagnetic Wave from the sun such as light usually reflects horizontally off of surfaces. This process produces a super annoying glare that polarized sunglasses restrict from affecting your eyes. 3. In your own words‚ explain why we see a rainbow or colorful sunset. Explain the properties and interactions that make this display possible. (13 points) Sunlight is actually made up of a whole range of colors but when all these colors are combine it is seen as white. When the light passes through different types

wavelength of visible light affects the rate of growth of aquatic plants Different wavelengths of light will effect to rate of photosynthesis. I will test this by exposing the pondweed to different wavelengths of light to see how it reacts. Method I will do this by passing white light through a filter. The filter will remove all unwanted wavelengths of light leaving the plant exposed to only the desired wavelength of light. I will use three different wavelengths of light 750nm (red)‚ 650nm
