What is photosynthesis?
What is photosynthesis?
The process of preparing or synthesising food using water from the soil and carbon dioxide from the air, together chlorophyll and sunlight is called photosynthesis. This entire process is a series of complex chemical reactions Photosynthesis is represented as follows:
Where does photosynthesis occur in a plant?
(iv) Photosynthesis occurs only in chlorophyll-containing parts of the plant. Question 7. Differentiate between aerobic and anaerobic respiration. Write the overall chemical equations of the two kinds of respiration in plants. It occurs in the presence of oxygen.
Which is the ultimate source of energy in photosynthesis?
Light is the ultimate source of energy in photosynthesis because plants take in the sunlight CO 2 and H 2 O and converts it into glucose. Question 4. Which gas is taken in and which one is given out by the leaf in bright sunlight? Question 5. Question 6. (i) Green plants prepare their food by using two raw materials, oxygen and water. False.

– Types & Site Of Photosynthesis What Is Photosynthesis? “Photosynthesis is the process used by green plants and a few organisms that use sunlight, carbon dioxide and water to prepare their food.” The process of photosynthesis is used by plants, algae and certain bacteria that convert light energy into chemical energy.
What are the components of the photosynthesis apparatus?
The photosynthesis apparatus includes the following essential components: Pigments not only provide colour to the photosynthetic organisms, but are also responsible for trapping sunlight. The important pigments associated with photosynthesis include:
How does water stress affect photosynthesis in grapevines?
Dordrecht, The Netherlands: Springer. pp. 66–79. ^ Flexas J, Escalnona JM, Medrano H (January 1999). “Water stress induces different levels of photosynthesis and electron transport rate regulation in grapevines”.
How does photosystem II work?
Photosystem II replenishes the lost electrons from an external source, but the remaining electrons still do not return to PSII as it happens in the cyclic pathway. Instead, these electrons are transferred to the PSI complex, which, together with a second solar photon, increases the energy levels.
