Where Does Photosynthesis Take Place In A Plant Cell?


Where Does Photosynthesis Take Place In A Plant Cell?

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 does most photosynthesis take place?

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.

Where does photosynthesis take place and why?

Photosynthesis a plant’s internal process that converts light energy into food takes place mostly in the leaves of plants. Plants and trees utilize specialized structures to conduct the chemical reactions necessary to transform sunlight into chemicals the plant can use.

Why does photosynthesis occur in plant cells?

Plants are autotrophs which means they produce their own food. They use the process of photosynthesis to transform water sunlight and carbon dioxide into oxygen and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Why photosynthesis takes 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.

Does photosynthesis occur in stems?

Plant photosynthesis occurs in leaves and green stems within specialized cell structures called chloroplasts. … Additional light-trapping pigments enzymes (organic substances that speed up chemical reactions) and other molecules needed for photosynthesis are also located within the thylakoid membranes.

Can photosynthesis take place at night?

Photosynthesis doesn’t occur at night. When there is no photosynthesis there is a net release of carbon dioxide and a net uptake of oxygen. If there is enough light during the day then: the rate of photosynthesis is higher than the rate of respiration.

Where in the chloroplast does photosynthesis take place?


Photosynthesis: The Basics

Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).

Where does each part of photosynthesis occur?


Key Terms
Term Meaning
Chloroplast The plant cell structure where photosynthesis occurs
Thylakoids Disc-like structures within a chloroplast that help absorb light
Grana Stacks of thylakoids in a chloroplast
Chlorophyll A pigment found in the thylakoid that absorbs light energy and uses it to produce carbohydrates

What are the two location of photosynthesis?


Location of Photosynthesis

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

How do plants carry out photosynthesis?

Plants use their leaves to make food. … During photosynthesis plant leaves take in carbon dioxide from the atmosphere. Using the energy from sunlight this is combined with water drawn up from the roots to make glucose. Oxygen is also produced in this chemical reaction and exits the leaves into the surrounding air.

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.

How do plants photosynthesize?

Plants use a process called photosynthesis to make food. 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.

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.

Does photosynthesis take place in the epidermis?

The upper and lower epidermal cells do not have chloroplasts thus photosynthesis does not occur there. …

Which major tissue takes part in photosynthesis?

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 does photosynthesis takes place in plants stem root pistil leaves?

In plants and algae photosynthesis takes place in organelles called chloroplasts. A typical plant cell contains about 10 to 100 chloroplasts. The chloroplast is enclosed by a membrane.

Can photosynthesis take place in other parts of the plant?

Leaves are the primary organs that carry out photosynthesis. There are other plant parts also which perform photosynthesis such as modified stem roots etc. E.g. assimilatory roots contain chlorophyll and perform photosynthesis. They are aerial adventitious roots present in plants such as Trapa and Tinospora.

In which plant does photosynthesis take place in the stem rather in the leaves?


Photosynthesis takes place in the stems of the cacti rather than the spines (leaves).

Can photosynthesis take place without sunlight?

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 do plant do at night?

While the sun shines plants perform photosynthesis. In this process the plants convert sunlight water and carbon dioxide into stored energy in the form of long chains of sugar called starch. At night the plants burn this stored starch to fuel continued growth.

Can photosynthesis occur without water?

Water is needed for photosynthesis the process by which a plant uses sunlight to turn water and carbon dioxide into energy! The byproduct of this process lucky for us is oxygen.

Where does the first stage of photosynthesis take place?


The first step of photosynthesis occurs in the chloroplasts of plant cells. Light photons are absorbed by a pigment called chlorophyll which is abundant in the thylakoid membrane of each chloroplast.

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.

Which of these occur in photosynthesis?

The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions which take place in the thylakoid membrane use light energy to make ATP and NADPH.

What reaction takes place during 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 part does chlorophyll play in photosynthesis?

Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose a type of sugar.

What is photosynthesis function?

The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part the planet’s living systems are powered by this process. … Photosynthesis happens in regions of a cell called chloroplasts.

What are the steps in photosynthesis and where do they occur in the chloroplast?

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).

What four things are needed for photosynthesis to take place?

The process of photosynthesis

Photosynthesis takes place in the part of the plant cell containing chloroplasts these are small structures that contain chlorophyll. 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).
