Where does photosynthesis take place explain? In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
What is photosynthesis Where does it take place? In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4).
Where does photosynthesis take place first? Leaves are sites of photosynthesis
All green plant tissues can photosynthesize, but in most plants, but the majority of photosynthesis usually takes place in the leaves. The cells in a middle layer of leaf tissue called the mesophyll are the primary site of photosynthesis.
Does photosynthesis take place in stem? Photosynthesis takes place primarily in leaves and little to none occurs in stems. It takes place within specialised cell structures called chloroplasts.
Where does photosynthesis take place explain? – Related Questions
What is photosynthesis explain in detail?
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.
In which light photosynthesis takes place faster?
As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. After white, we have violet light where photosynthesis occur to a higher extent as it has the shortest wavelength hence has the max energy.
Does photosynthesis occur in all plant cells?
Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.
What are the 3 stages 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.
Can photosynthesis occur in the dark?
Plants need light to photosynthesize, but it doesn’t necessarily have to be sunlight. If the correct type of artificial light is used, photosynthesis can happen at night with lights that contain blue and red wavelengths.
What are the names of the stages of photosynthesis?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).
In which plant stem is photosynthesis carried out?
Answer: CAM stem photosynthesis occurs in succulent species to maximize water use efficiency. Stem photosynthesis is similar to C3 leaf photosynthesis and occurs in species inhabiting a diversity of high-light sites.
In which plant Kranz anatomy is found?
Hint: Kranz anatomy is a specialized structure in C4 Plants where the mesophyll cells are clustered around the bundle-sheath cells in a ring-like fashion. This is found in C3 grasses such as maize and a few dicots. Complete answer: Kranz anatomy is the unique structure found in C4 plants.
What will happen in the absence of photosynthesis?
If photosynthesis does not occur in plants then plants cannot synthesize the food. The plants will not produce oxygen and then no animal life will be able to survive due to the absence of oxygen. We will not get oxygen, food, and life on this planet will be extinct.
What is the importance of photosynthesis?
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
What is photosynthesis short answer?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that plants also need oxygen. So plants need to breathe — to exchange these gases between the outside and the inside of the organism.
Which Colour is best for 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 color has the highest rate of photosynthesis?
White light appears to be the most effective light for photosynthesis, but apart from white, red light is also effective. When white light is not used, red is more effective than its counterparts, most likely because red light has a long wavelength that allows it radiate more energy and heat than other colors.
In which Colour photosynthesis is minimum?
In the absorption spectrum, it can be shown that red light and blue light are absorbed the most whereas the green light is most commonly reflected. Therefore minimum photosynthesis takes place in green light. So, the correct answer is, ‘Blue and Green light.
Where does the most photosynthesis occur in a plant?
You should notice that the vast majority of chloroplasts are found in the cells of the mesophyll. Even more specifically, the palisade layer has the most chloroplasts, so the greatest amount of photosynthesis occurs in that leaf layer.
In which light photosynthesis is maximum?
In order to absorb the blue color of light in the greatest quantity, the maximum intensity of photosynthesis occurs in red light. So, the correct answer is, ‘Red light’. Note: Chlorophyll is a green-colored pigment that in plants absorbs light for photosynthesis.
Why does photosynthesis occur in plant cells?
Green plants use photosynthesis to create energy from carbon dioxide and sunlight. This energy, in the form of glucose, is used by the plant to grow and fuel the necessary reproductive activities of the plant. Excess glucose is stored in the leaves, stem and roots of the plant.
How do plants produce ATP?
Plants, through the process of photosynthesis, make use of the sunlight to energise and generate glucose through the available water and carbon dioxide. Through cellular respiration, pyruvate in turn gives ATP (adenosine triphosphate).
Can photosynthesis occur in moonlight?
The light intensity that we get reflected off the moon is an order of 100-1000 times too little to support photosynthesis in most terrestrial plants/trees. Moonlight from full moon can support a small amount of photosynthesis in certain plant life – maybe algae, plankton.
Do plants respire at night?
During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration.
