In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Where is the site for most photosynthesis?
Photosynthesis occurs within organelles called the chloroplasts that are abundant on the leaf of a plant, giving it its signature green pigment. Of course, the leaf is not the only photosynthetic part of the plant; it’s just where most of it happen most of the time.
What are the sites of photosynthesis?
Photosynthesis takes place in special organelles known as chloroplast. This organelle has its own DNA, genes and hence can synthesize its own proteins. Chloroplasts consist of stroma, fluid, and stack of thylakoids known as grana.
What is the site of photosynthesis in chloroplast?
Chloroplast. … Interior of chloroplast contains closely packed flattened sacs called thylakoid organised in grana. The thylakoid membrane contains the pigment chlorophyll. The grana are the site of light reaction of photosynthesis.
How many sites of photosynthesis are there?
There are two photosystems located in the thylakoid membranes of the chloroplast. Photosystems are functional protein units tasked with the primary photochemistry of photosynthesis; absorbing light and transferring electrons and energy. They can be identified based on the wavelength at which they are most active.

Chloroplast is the site of photosynthesis. It is present in the mesophyll cell of the leaf. Chloroplast contains chlorophyll pigment.
What is the site of photosynthesis quizlet?
Photosynthesis occurs in the chloroplast. What are chloroplasts and where are they found? Chloroplast is an organelle found in the leaves of green plants. They are found in a plant cell.
Where is chlorophyll located?
Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells.
What is the site of photosynthesis in chloroplast and mention where does the dark and light reaction actor in it?
In eukaryotic cells, both the light and dark reactions of photosynthesis occur within chloroplasts—the light reactions in the thylakoid membrane and the dark reactions within the stroma. This section discusses the light reactions of photosynthesis, which are related to oxidative phosphorylation in mitochondria.
What is photosynthesis class 9th?
Photosynthesis is a physiological process by which plant cells containing chlorophyll produce food in the form of carbohydrates by using carbon dioxide, water and light energy.
What is the site of photosynthesis in green plants Class 7?
Chloroplast is the site of photosynthesis. At the end of photosynthesis, carbohydrate and oxygen are formed. Carbohydrate is used as food and oxygen is emitted out to the atmosphere.
What is the site of photosynthesis in Opuntia?
Chloroplasts are the actual sites for photosynthesis. All green parts of a plant are involved in photosynthesis. Leaves are the most important organs of photosynthesis. In xerophytes like Opuntia, the stem is green and it performs photosynthesis.
What is meant by photosynthesis What is the site of photosynthesis in plants Class 6?
Answer: leaves prepare their food in the presence of sunlight and a green coloured substance present in them , they also use water and carbon dioxide. this process is called photosynthesis. the site of photosynthesis in plants : mesophyll of the leaves , inside the chloroplasts.
What is photosynthesis class 8th?
Photosynthesis is the physico-chemical process by which plants can convert light energy into chemical energy, in the form of carbohydrate from simple inorganic substances like atmospheric carbon dioxide and water.
Where does photosynthesis take place in plants quizlet?
Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll.
Which organelle is the site of photosynthesis quizlet?
Photosynthesis occurs within the organelle called the chloroplast. Photosynthesis happens in the plant kingdom called for example a sun flower uses the process of photosynthesis to make food for itself.
In which part of a chloroplast does photosynthesis occur quizlet?
They produce the source of chemical energy for themselves and for other organisms. In what two parts in a chloroplast does photosynthesis take place? The Grana and The Stroma.
Where is chlorophyll located Class 10?
Chlorophyll is located within the thylakoid membrane of the chloroplast. Chlorophyll is found in virtually all photosynthetic organisms, including green plants, cyanobacteria, and algae.
Where in the chloroplast would one find chlorophyll molecules?
Chlorophyll is found in the photosystem antenna complex embedded in the thylakoid membrane.
What is the site of light and dark reaction?
The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs. … Note that the dark reaction takes place in the stroma (aqueous fluid surrounding the stacks of thylakoids) and the cytoplasm.

Which is the site of dark phase?
The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction. Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle.
What is photosynthesis for class 7th?
The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. … Carbon dioxide + Water → Glucose + Oxygen. The process of photosynthesis takes place in the leaves of a plant.
What is photosynthesis for kids?
Photosynthesis is the process in which green plants use sunlight to make their own food. … Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest.
What is photosynthesis class 4th?
Answer: It is the process by which plant manufacturers their own food in the presence of sunlight and chlorophyll with the help of carbon dioxide and water.
What is the site of photosynthesis in green plant very short?
chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.
What is the organ and site of photosynthesis in green plants?
Answer: Organ-leaf; site-chloroplast in the leaf ; Raw materials- carbon dioxide,water,sunlight, chlorophyll. They are obtained in the following ways: Carbon dioxide- Land plants absorb carbon dioxide from the air while aquatic plants absorb carbon dioxide dissolved in water.
Is the site of reception of light energy in leaves?
Chloroplasts have chlorophyll, which is a green pigment that traps light energy and convert it to chemical energy.
What is the site for photosynthesis in Opuntia Class 11?
In xerophytes like Opuntia, the stem is green and it performs photosynthesis.
What is the stalk of a leaf?
The petiole is a stalk that connects the blade with the leaf base.
What are the reactants in photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is the site of respiration?
Mitochondria is the site where cellular respiration takes place resulting in the production of ATP that serves as a source of energy for important metabolic processes.
