How do you explain photosynthesis?
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What is a short summary of photosynthesis?
Photosynthesis is a multi-step process that requires sunlight, carbon dioxide, and water as substrates. It produces oxygen and glyceraldehyde-3-phosphate (G3P or GA3P), simple carbohydrate molecules that are high in energy and can subsequently be converted into glucose, sucrose, or other sugar molecules.
What occurs in the process of photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
What are the photosynthesis products?
Summary. The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas.
What are the major events of photosynthesis?
The three major events that occur during the process of photosynthesis are: > Absorption of light energy by chlorophyll. > Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
What is photosynthesis explain with diagram?
Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
How does photosynthesis work simple?
Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.
What color light is best for plant growth?
Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.
What are stomata very short answer?
Stomata are small pores present in the leaf. They are surrounded by gaurd cells which help in closening and opening of stomata. 1)They allow exchange of gases from the surrounding medium. Usually, carbon dioxide is taken up and oxygen is released.
What is the importance photosynthesis?
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.
In which light photosynthesis takes place faster?
white light
What are the 7 steps of photosynthesis?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
Does the color of light affect plant growth?
The color of light DOES affect plant growth, but the effect is more noticeable under low light intensity. Red & blue light are most effective for plant growth, while yellow & green have minimal effect. UV light can damage plants, causing leaves to burn. Growers often use supplemental light to optimize plant growth.
What gas is used in photosynthesis?
carbon dioxide
What are the two main steps in photosynthesis?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
In which light photosynthesis is maximum?
red light
In which Colour photosynthesis is minimum?
The green light is considered to be the least efficient wavelength for photosynthesis.
What is photosynthesis rate?
The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds. Net photosynthesis is negative in darkness, when respiration exceeds photosynthesis, and increases with the intensity of PAR.
What are examples of photosynthesis?
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. The water from the leaves evaporates through the stomata, and filling its place, entering the stomata from the air, is carbon dioxide. Plants need carbon dioxide to make food.
What is photosynthesis essay?
Photosynthesis is one of the most fundamental biological reactions. The chlorophyll bearing plants trap the free energy of sunlight as photons and transform and store it as chemical potential energy by combining CO2 and water. The end products of photosynthesis are carbohydrates with loss of oxygen.
What color light do plants absorb best?
Blue is the most important light for plant growth, because it is readily absorbed by chlorophyll and converted into energy through photosynthesis. That said, blue light on its own is not nearly as effective as blue combined with red.
Which light is most effective in photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
What is the best type of grow light?
LEDs are great for your plants.
- LEDs are great for your plants.
- Though they cost a bit more up front, LEDs are super-efficient.
- They’re earth-friendly.
- Fluorescent lights are more affordable, and may be a good choice if you’re new to indoor gardening or grow just a few plants.
What is photosynthesis introduction?
Overview. Photosynthesis is the process by which plants, some bacteria, and some protistans convert light energy (sun) into chemical energy (food). These organisms are referred to as the Producers and they are vitally important to all life on earth.
Why is white light best for photosynthesis?
White light is the most effective light for photosynthesis because it provides a wide range of colored lights for various pigments to use. When only a single color is used, red is the most effective color of light.
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.
What color do plants reflect?
Green light
What are the three main steps of photosynthesis?
The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.
Why do plants absorb red and blue light better?
Red and yellow light is longer wavelength, lower energy light, while the blue light is higher energy. That makes it impossible to assign a single wavelength of best absorption for all plants. All plants, however, has chlorophyll a, which absorbs most strongly at ~450 nm, or a bright blue color.
