What is site of photosynthesis?ans in detail:--?

Question

Answer

The Cell. All green parts of a plant, including green stems and unripened fruit, have chloroplasts, but the leaves are the major sites of photosynthesis in most plants (FIGURE 10.2).. ... It is the light energy absorbed by chlorophyll that drives the synthesis of food molecules in the chloroplast....

Answer

जिस process से green plants अपना food बनाते हैं उसको हम photosynthesis कहते हैं। Photosynthesis का process chloroplast में sunlight, water और carbon dioxide के द्वारा chlorophyll के presence में होता है।

Answer

Leaves are the major photosynthetic organs of a plant . They have large surface area in the form of leaves, vascular tissue for food and water supply and apparatus for gaseous exchange . Leaves contain green coloured cell organelles called chloroplast .
Chloroplast are the site of photosynthesis as they contain chlorophyll pigment.

Answer

6co2+12H²o---->C6H12O6+6o²

Answer

Photosynthesis Takes place in Chloroplast which contain chlorophyll.  It absorbs the sunlight by which photosynthesis happen.. in which sunlight is converted in chemical energy..

Answer

Answer

Chloroplasts in the cell is the site of photosynthesis

Answer

Plant leaves, chloroplasts make the green pigment chlorophyll. This is the substance that can extract energy from sunlight. Plants use the energy to create glucose and oxygen from the raw materials carbon dioxide and water. In plant leaves, this takes place in a layer called the mesophyll.

Answer

The Site of Photosynthesis

Photosynthesis is a vital process carried out by plants, algae, and some bacteria, through which light energy is converted into chemical energy. The site of photosynthesis varies depending on the organism, but in general, it occurs in specialized structures within cells called chloroplasts.

Chloroplasts and Their Structure:
Chloroplasts are organelles found in the cells of plants and algae that are responsible for photosynthesis. They are typically oval-shaped and have a double membrane. The inner membrane encloses a fluid-filled space called the stroma, while the outer membrane separates the chloroplast from the rest of the cell. Within the stroma, there are numerous flattened sacs called thylakoids, which are organized into stacks known as grana. Thylakoids contain chlorophyll, the pigment that captures light energy.

Leaf Anatomy:
In plants, the primary site of photosynthesis is the leaves. Leaves have a specialized structure that maximizes their exposure to light and facilitates gas exchange. The main components of a leaf are the epidermis, mesophyll, and vascular tissue.

1. Epidermis:
The epidermis is the outermost layer of the leaf and is covered by a waxy cuticle, preventing excessive water loss. It also contains small openings called stomata, which allow for the exchange of gases, such as carbon dioxide and oxygen, between the leaf and the environment.

2. Mesophyll:
The mesophyll is the middle layer of the leaf and is divided into two types: the palisade mesophyll and the spongy mesophyll. The palisade mesophyll is located just beneath the upper epidermis and contains tightly packed cells with numerous chloroplasts, maximizing light absorption. The spongy mesophyll lies beneath the palisade mesophyll and has loosely arranged cells that facilitate gas diffusion.

3. Vascular Tissue:
The vascular tissue of a leaf consists of xylem and phloem. Xylem transports water and minerals from the roots to the leaf, while phloem carries the sugars produced during photosynthesis to other parts of the plant.

Light Reactions and Calvin Cycle:
The process of photosynthesis can be divided into two main stages: the light reactions and the Calvin cycle.

1. Light Reactions:
The light reactions occur in the thylakoid membranes of the chloroplasts. During this stage, light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH. Water molecules are also split, releasing oxygen as a byproduct.

2. Calvin Cycle:
The Calvin cycle takes place in the stroma of the chloroplasts. In this stage, ATP and NADPH generated during the light reactions are used to convert carbon dioxide into glucose through a series of chemical reactions. This glucose can be stored as starch or used for energy production in the plant.

Conclusion:
In summary, photosynthesis occurs in specialized structures called chloroplasts, primarily located in the leaves of plants. The chloroplasts contain chlorophyll, which captures light energy, and the process of photosynthesis involves both the light reactions in the thylakoid membranes and the Calvin cycle in the stroma. Understanding the site of photosynthesis and its intricate processes is crucial for comprehending the fundamental role of plants in maintaining the balance of ecosystems and providing energy for life on Earth.
