What kind of energy is used in the process of photosynthesis?
Photosynthesis uses light energy from the sun to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells and is essential for plants to produce their own food.
Which pigment is directly involved in the light reactions of photosynthesis?
The pigment directly involved is the green pigment called 'chlorophyll' and is found in the chloroplats.
What converts light energy into chemical energy sugars through the process of photosynthesis?
Chlorophyll, a green pigment found in chloroplasts of plant cells, converts light energy from the sun into chemical energy through the process of photosynthesis. This process involves capturing light energy to produce sugars (such as glucose) from carbon dioxide and water.
What is the process when plants change light energy into chemical energy?
Plants use a process called photosynthesis to convert light energy into chemical energy. During photosynthesis, plants absorb light energy, which is used to convert carbon dioxide and water into glucose (sugar) and oxygen. This process occurs in chloroplasts, which contain chlorophyll, the pigment that captures light energy.
Does photosynthesis need the suns heat energy or the suns light energy?
Photosynthesis primarily relies on the sun's light energy, which is captured by chlorophyll in plant cells to drive the photosynthetic process. While some heat energy may be generated as a byproduct of photosynthesis, it is not the main source of energy for the process.
Which example involves the transformation of chemical energy directly into light energy?
The example of a firefly producing light involves the transformation of chemical energy (from its food) directly into light energy through a process known as bioluminescence. This chemical reaction occurs within the firefly's body and results in the emission of light without the need for an external light source.
What is the energy change in a LED?
In a LED, electrical energy is converted directly into light energy, resulting in a decrease in electrical energy and an increase in light energy. This process is much more efficient than traditional incandescent bulbs, which waste energy as heat.
Electrical energy is the energy of?

What are the light requirement in respiration?
Light is not a requirement for respiration directly. Respiration is a cellular process where cells break down glucose to produce energy in the form of ATP. Light is essential for photosynthesis, a process where plants use light energy to convert carbon dioxide and water into glucose and oxygen.
What transforms electrical energy to light energy?
An incandescent light bulb transforms electrical energy into light energy by passing an electric current through a filament, which heats up and emits light as a result of its high temperature. LED lights use a semiconductor material to convert electrical energy directly into light energy through a process called electroluminescence.
Which of the following substances is directly involved in photosynthesis?
Chlorophyll is the substance directly involved in photosynthesis. It is a pigment found in the chloroplasts of plant cells that absorbs light energy and converts it into chemical energy during the process of photosynthesis.
Light energy is required for this process?
Light energy IS required for Photosynthesis
What is the energy for this process of chloroplasts?
Light energy from sun is used. Chlorophylls capture light energy
What is the relationship between the intensity and energy of light?
The relationship between the intensity and energy of light is that the intensity of light is directly proportional to its energy. This means that as the intensity of light increases, so does its energy.
What kind of energy is used in the process of photosynthesis?
Photosynthesis uses light energy from the sun to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells and is essential for plants to produce their own food.
Is energy of light directly proportional to frequency?
Yes, the energy of light is directly proportional to its frequency. This relationship is described by Planck's equation, E=hf, where E is the energy of a photon of light, h is Planck's constant, and f is the frequency of the light.
How does the amount of electrical energy used compared to the amount of light energy produced?
The amount of electrical energy used by a light source does not directly translate to the amount of light energy produced due to efficiency losses in the conversion process. Light sources vary in their efficiency in converting electrical energy to light energy, so it's not a one-to-one relationship. LEDs, for example, are more efficient at converting electrical energy to light energy compared to incandescent bulbs.
