How many watts does it take to produce photosynthesis?
For optimum lumens, you need between 20 (min) and 60 (max) watts per sq ft. For example: if you have a 4′ x 4′ area, which equals 16 sq ft, multiplied by 30 watts you get 480 watts. That means you need at least a 400 watt light; but would do much better with a 600 watt or 1000 watt Grow Light.
How does Rafflesia do the photosynthesis?
Rafflesia (pronounced rah-FLEEZ-ee-ah) lives inside the tissue of a tropical vine related to the grapevine, with only its flower visible. It is devoid of leaves, shoots and roots, and does not engage in photosynthesis, the process plants use to exploit the energy from sunlight.
What wavelengths work best for photosynthesis?
Visible light ranges from low blue to far-red light and is described as the wavelengths between 380 nm and 750 nm, although this varies between individuals. The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).
What is the highest rate of photosynthesis?
The maximum rate of photosynthesis occurs in the red and blue regions of the visible light as seen in the absorption spectra of chlorophyll a and b.
Can plants use LED light for photosynthesis?
Light-emitting diode or LEDs are beneficial for this purpose as they can mimic the artificial light to ensure the proper development of plants without burning them. During photosynthesis, light energy is converted into chemical energy.
Can photosynthesis occur in LED light?
Plants can do photosynthesis if the right spectrum of artificial light is provided, such as for indoor plants. This method is used to boost production to meet the demand. LEDs, or light-emitting diodes, are useful for this because they can mimic artificial light to ensure proper plant development without burning them.
How are the adaptations of the Rafflesia flower related to the process of natural selection?
Because the rafflesia does not have a chloroplast genome (lacks chlorophyll), it is incapable of photosynthesis. Instead, the tetrastigma vine that hosts the flower provides its nutrients and food. The rafflesia uses small filaments to extract the nutrients and water from the host vine.
How does the Rafflesia flower attract pollinators?
This it does by mimicking the stench of rotting meat to attract insects especially flies. The Rafflesia is also sometimes referred to as the corpse flower. Flies attracted to these flowers will unknowingly transfer pollen grains from a male flower to a female flower.
At what wavelength is the photosynthesis rate the maximum?
The rate of photosynthesis is maximum in red light. This was proved by the Emerson enhancement effect that states that there is an increase in the rate of photosynthesis when the chloroplast is exposed to a light of wavelength 680 nm and 700 nm.
At what time photosynthesis is maximum?
Light between 400-700 nm wavelength constitute the photosynthetically active radiation (PAR). Maximum absorption of light by chlorophyll a occurs in red and blue regions of the absorption spectrum. So that, the rate of photosynthesis is maximum in red and blue light of the visible spectrum.
What is the lowest rate of photosynthesis?
The green light is considered to be the least efficient wavelength for photosynthesis. During photosynthesis, if the plants are exposed to green wavelength, the rate at which the photosynthesis takes place will be the least.
How much light intensity is needed for photosynthesis?
The part of the solar spectrum used by plants has an estimated mean wavelength of 570 nm; therefore, the energy of light used during photosynthesis is approximately 28,600/570, or 50 kcal per einstein.
Will normal LED lights grow plants?
Yes, plants will grow under normal LED lights. Grow lights aren’t special – they’re just strong. Bright light causes plants to grow, whether they’re marketed as grow lights or not. They do need to be close to them though – the closer the better (without them burning).
Do all LED lights grow plants?
LED grow lights come in a spectrum of colors and a wider range of wattages than regular white LEDs. Since regular white LEDs are cheaper than LED grow lights, you can always experiment with them first. Plants will certainly grow under white LED lighting, but they probably won’t thrive.
Can plants grow with just artificial light?
Plants can grow in artificial light, but artificial light isn’t as intense as sunlight and has less red and blue light than sunlight. LED lights used in special indoor growth chambers reduce the difference between artificial light and sunlight, which can help plants grow better.
How does the Rafflesia get its nutrients?
In fact, the Rafflesia arnoldii is known as the “corpse flower” because it smells like dead flesh. And unlike most plants, this flower does not use energy from the Sun to make its own food. Instead, it is a parasite: it gets all its nutrients and water from a host, a vine in the grape family.
In which wavelength of light photosynthesis is minimum?
green light
Light between 400-700 nm wavelength constitute the photosynthetically active radiation (PAR). Maximum photosynthesis takes place in red and blue light of the visible spectrum and minimum photosynthesis takes place in the green light.
In which light rate of photosynthesis is very high?
Red light
Red light is absorbed maximum by chlorophyll. So, the rate of photosynthesis is higher in the red light of the visible spectrum. The wavelength of light least effective in photosynthesis is green because plants themselves are green due to the pigment Chlorophyll.
In which light rate of photosynthesis is minimum?
Therefore minimum photosynthesis takes place in green light.
What wavelength has the fastest rate of photosynthesis?
Out of the colored lights blue had the shortest wavelength and the fastest rate of photosynthesis.

What is the first visible product of photosynthesis?
Julius Von Sachs in 1854 shows that green part in plants produces glucose which is stored as starch. Starch is the first visible product of photosynthesis. T.W.Engelmann (1843-1909) used prism to split light into its components and then illuminated Cladophora (an algae) placed in a suspension of aerobic bacteria.
What are the factors that affect the rate of photosynthesis?
Light- as light intensity increases, the rate of photosynthesis also increases until light saturation point. Carbon dioxide concentration – with increase in concentration of rate of photosynthesis increase till the compensation point.
