Effect of different colors of light on the rate of photosynthesis.

LED CY60 provides daylight conditions, also simulating lunar lighting, which creates a shimmering effect for plants, coral and fish. 70% of the spectral energy is distributed at 460nm, providing the most suitable light for plants or coral photosynthesis. Light can penetrate up to 3m into the water. LED is 3 times brighter than High pressure sodium or T5 HO under the same power. Double switches with dimmers can control blue and white lights separately.

FOBSUN LED CY60 Aquarium Lamps come with Bridgelux LED’s, the lastest LED optic lens which improves brightness by 20 – 30%. The new stylish LED aquarium lamp has a beam angle of 120 degrees. 2 durable on/off switches with dimmers can control white or blue colour respectively. With large aluminium alloy heat sink, the advanced LED aquarium lamps can emit exact wavelengths to facilitate photosynthesis of Corals & Plants without increasing water temperature. The external power supply with SAA certificates ensures high energy efficiency. Built-in advanced thermal management system ensures that the housing temperature will not exceed 40 C. The stylish mounting legs can greatly facilitate the installation process. With durable aluminium alloy housing, the CY60 LED aquarium lamp can last over 50,000 hours.

I then think that the rate of photosynthesis will stay the same when it reaches a certain point.

Effects of different colors of light on the photosynthesis rate.

The Plan In my experiment I am going to see how light affects the rate of photosynthesis.

Effect of different colors of light on the rate of photosynthesisThe effect of different lights on plant growth: incandescent light, fluorescent light, sunlight and black light.

Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.

Photosynthesis can be measured in many ways as it involves the production of oxygen, the uptake of carbon dioxide and an increase in biomass. For example, aquatic plants release oxygen bubbles during photosynthesis and so these can be collected and measured. The uptake of carbon dioxide is more difficult to measure so it is usually done indirectly. When carbon dioxide is absorbed from water the pH of the water rises and so this can be measured with pH indicators or pH meters. Finally, photosynthesis can be measured through an increase in biomass. If batches of plants are harvested at a series of times and the biomass of these batches is calculated, the rate increase in biomass gives an indirect measure of the rate of photosynthesis in the plants.

The rate of photosynthesis was recorded at a range of light Intensities and conditions.

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....

PAR is an important and accepted starting point to estimate light energy for our photosynthetic aquarium keeping needs. We measure PAR via µMolm which is a unit of measure (more about measurement later).

Light wavelengths affecting the rate of photosynthesis - AP …

Photosynthetic invertebrates (many corals, anemones, clams, nudibranch, etc.) also need more blue (400-490nm) than "higher" plants especially as tanks increase in depth, such as the 465-485 blue spectrum. Not only is blue/actinic lighting beneficial to photosynthetic invertebrates, it is also aesthetically pleasing to the eye and the 420 nm blue in particular brings out the colors of many corals/clams.
Osram Oslon now has a "patent pending" LED emitter (the NP Blue) that is the first 'blue' emitter SPECIFICALLY designed for the full PAR spectrum required by marine photosynthetic invertebrates (see for more)

what is the effect of light wavelength on rate of photosynthesis?

This desire to discover new ways of producing clean energy has lead scientists at Stanford University and other universities to discover a way to harness the electricity produced during the process of photosynthesis.

How does wavelength of light affect the rate of photosynthesis?

Most photosynthetic marine invertebrates should be kept with lamps of a daylight Kelvin temperature from 6400-14,000 K (higher Kelvin with deeper specimen placement, not necessarily tank depth). 20,000K daylight lamps can also be used for deeper tanks (over 22 inches) and/or supplementation with more blue lights (400nm- 490nm).

How does light intensity affect the rate of photosynthesis

6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....

How Does Light Intensity Affect the Rate of Photosynthesis

*Chlorophyll B; The chlorophyll that occurs only in plants & green algae. It functions as a light harvesting chlorophyll pigment that pass on the light excitation to chlorophyll a. It absorbs well at wavelength of 450-500 nm & 600-650 nm

Since many photosynthetic organisms live where light in higher spectrums of PAS such as 600nm & higher penetrate less if at all (in particular algae, zooxanthellae, & cynaobacteria), many have adapted to ways to still harvest this light energy.
These organisms use Phycobilisomes which are light harvesting antennae of photosystem II (Chlorophyll synthesis in the Photosynthic Action Spectrum-PAS).

How does the colour of light affect the rate of photosynthesis

Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.
