Where does photosynthesis in the plant mainly take place?

chloroplasts

Photosynthesis takes place inside plant cells in small objects called chloroplasts . Chloroplasts contain a green substance called chlorophyll . This absorbs the light energy needed to make photosynthesis happen. Plants and algae can only carry out photosynthesis in the light.

Where photosynthesis occurs in leaves?

In plants photosynthesis generally takes place in leaves which consist of several layers of cells. The process of photosynthesis occurs in a middle layer called the mesophyll.

Why does photosynthesis mostly take place in the leaves?

Photosynthesis primarily happens in green leaves (not colorful autumn leaves). Leaves are ideal for photosynthesis because they are usually broad and flat giving plenty of surface area for light to be absorbed. They are also thin which means diffusion of gases such as carbon dioxide can happen quickly.

Where does most of the photosynthetic activity take place in the plant leaf?

chloroplasts

The most important part of photosynthesis occurs in the chloroplasts. These small photosynthesis factories buried within the leaves house chlorophyll a green pigment secreted in the chloroplast membranes.

How does photosynthesis work in a leaf?

During photosynthesis plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Where are chloroplasts found in a leaf?

leaf mesophyll
In plants chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

In which part of a chloroplast does photosynthesis occur?

thylakoid membranes

Photosynthesis occurs in the chloroplast an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH which temporarily store chemical energy.

What are the two location of photosynthesis?

chloroplasts

Location of Photosynthesis

Photosynthesis occurs in chloroplasts found in the leaves and green stems of plants.

Does photosynthesis take place only in green leaves?

photosynthesis take place only in green plant because they are the only living things which use carbon dioxide chlorophyll sunlight for making their food. Photosynthesis can only take place in green plants because they contain a special green pigment (substance) called chlorophyll on its surface.

What plant does the most photosynthesis?

C4 plants

The C4 plants show a high rate of photosynthesis compared to C3 plants. The photosynthetic rate in such plants is known to be directly related to the variation of the solar rays in the daytime.

What is photosynthesis explain the process of photosynthesis in the plants?

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 needed in photosynthesis?

For photosynthesis to take place plants need to take in carbon dioxide (from the air) water (from the ground) and light (usually from the sun).

What are the events occur during the process of photosynthesis?

The 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.

What part of the leaf has the most chloroplasts?

palisade parenchyma

Leaf mesophyll composed of parenchyma tissue. The elongated palisade parenchyma contains the largest number of chloroplasts per cell and is the primary site of photosynthesis in many plants.

Where are stomata located on a leaf?

underside
stomate also called stoma plural stomata or stomas any of the microscopic openings or pores in the epidermis of leaves and young stems. Stomata are generally more numerous on the underside of leaves.

What cell layer inside the leaf has the most chloroplasts?

Palisade mesophyll layer

Palisade mesophyll layer:

See also How Does Altitude Affect Pressure?

Tightly packed layer of elongated cells located directly below the upper epidermis. These cells contain most of the chloroplasts in a leaf.

Where does photosynthesis occur in a leaf state which organelles carry out photosynthesis and which type or types of leaf cells have this organelle?

the chloroplast

Photosynthesis occurs in the chloroplast an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH which temporarily store chemical energy.

Where does the first phase of photosynthesis take place?

chloroplasts
Both stages of photosynthesis take place in chloroplasts. The light reactions take place in the thylakoid membranes and the Calvin cycle takes place in the stroma. The light reactions capture energy from sunlight which they change to chemical energy that is stored in molecules of NADPH and ATP.Feb 23 2012

What process takes place in the stroma?

The series of biochemical redox reactions which take place in the stroma are collectively called the Calvin cycle or light-independent reactions. There are three phases: carbon fixation reduction reactions and ribulose 1 5-bisphosphate (RuBP) regeneration.

Does photosynthesis takes place in these leaves also?

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.

How does photosynthesis occur in green leaves?

Photosynthesis takes place inside plant cells in small objects called chloroplasts . Chloroplasts contain a green substance called chlorophyll . … Plants get carbon dioxide from the air through their leaves and water from the ground through their roots.

Is photosynthesis carried out only in leaves?

Answer: Photosynthesis is a process which mainly occurs in leaves of all green plants. The plants have designed their leaf in such a way that it is able to trap solar radiation and effectively convert solar/light energy to chemical energy.

Where does oxygenic photosynthesis occur?

Oxygenic photosynthesis is a process of a non-cyclic photosynthetic electron chain where the initial electron donor is water and oxygen is a byproduct. It is found in cyanobacteria (Oscillatoria) and plants. Anoxygenic photosynthesis is found in purple bacteria green sulfur (Chlorobium) nonsulfur bacteria etc.

Which part of plant do not perform photosynthesis?

the fungi are the plants which do not perform the photosynthesis as the fungi didn’t have the pigment called chlorophyll that play the main role in the process of photosynthesis. the chlorophyll pigment are used in trapping the sunlight to make the food of the plant by the process of photosynthesis.

Which of the following sequence is done by plants to process photosynthesis?

The steps of photosynthesis can be summarized by the following equation: 6 CO2 (carbon dioxide) + 6 H2O (water) + Energy = C6H12O6 (glucose)+ 6 O2 (oxygen). The carbon from carbon dioxide combines with hydrogen and oxygen from water to form glucose with oxygen and water as byproducts.

What is photosynthesis for kids?

Photosynthesis is the process in which green plants use sunlight to make their own food. … Photosynthesis requires sunlight chlorophyll water and carbon dioxide gas. Chlorophyll is a substance in all green plants especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.

What is photosynthesis What are the events that take place during this process write How does plant absorb carbon dioxide?

During photosynthesis plants take in carbon dioxide (CO₂) and water (H₂O) from the air and soil. … This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air and stores energy within the glucose molecules.

What are three major processes 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).

Which part of the leaf contains the most chloroplasts and why?

palisade layer
The palisade layer contains the most chloroplasts as it is near the top of the leaf. The chloroplasts contain the pigment chlorophyll. The palisade cells are arranged upright. This means the light has to pass through the cell lengthways and so increases the chance of light hitting a chloroplast and being absorbed.

Why does most photosynthesis occur in the palisade layer?

The cells in the palisade layer are jam-packed with chloroplasts. It is here in the palisade layer where there is an abundance of the green pigment chlorophyll that most of the photosynthesis for the plant takes place.

In what area of the leaf are the chloroplasts found quizlet?

the palisade mesophyll has the most chloroplasts and therefore the most green pigment chrlorophyll gives the leaf their green color. the upper epidermis and cuticle. three differences between the cells of the palisade mesophyll and the cells that make up the other areas within the leaf.

Which side of the leaf has more stomata?

lower epidermis

All surfaces of the leaf have some amount of stomata for regulating gas exchange for photosynthesis. However the lower epidermis (the underside of the leaf) has more because it is more often in the shade and so it is cooler which means evaporation won’t take place as much.
