Organelles, called plastids, are the main sites of photosynthesis in eukaryotic cells. Chloroplasts, as well as any other pigment containing cytoplasmic organelles that enables the harvesting and conversion of light and carbon dioxide into food and energy, are plastids.
Leaf is considered to be the best site of Photosynthesis because in a plant the leaves have the maximum surface area and it can perform photosynthesis in a more efficient way as the rate of photosynthesis increases with the increase in the surface area available for photosynthesis.
Leaves are the main sites for photosynthesis: the process by which plants synthesize food. Most leaves are usually green, due to the presence of chlorophyll in the leaf cells.
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. Oxygen is released as a by-product.
The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.Aug 21, 2014
Answer : Chloroplast are the sites of photosynthesis. … Chloroplast consists of thylakoids.
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 get carbon dioxide from the air through their leaves, and water from the ground through their roots.
In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis.
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
List out the different parts of Chloroplast?
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.
In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis. More chloroplasts means more photosynthetic capability.
Different Parts of a Plant
Structure-Function Relationship: Leaves
|Name of Structure||Structure||Function|
|Pith||Parenchyma with vacuoles and plastids||Storage, support|
|Plasmodesmata||Openings between sieve tubes connecting cytoplasm||Transport of sap|
|Spongy cells||Rounded, widely spaced, near stomata||Allow gas exchange|
Oxygen & carbon dioxide, water vapor as well. … Water, carbon dioxide enter the leaf cells. Sunlight energy powers photosynthesis as it enters through the cuticle & upper epidermis. Once oxygen & sugar are made during photosynthesis they are removed and transported to different locations.
Photosynthesis is a process which mainly occurs in leaves of all graeen 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. … Some plants carry us photosynthesis in modified plant parts other then leaves.
