Define photosynthesis?

Question

Answer

The process by which green plants make their food by the help of sunlight and water

Answer

Photosynthes is the process in which green plant use sunlight to synthesise nutrients from carbondioxide and water . during photosynthesis chlorophyll containing cell of leaves in the presence of sunlight use carbondioxide and water to synthesise carbohydrates..

Answer

Definition of Photosynthesis
Photosynthesis is a biochemical process through which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. This process is essential for life on Earth as it forms the foundation of the food chain and produces oxygen as a byproduct.
Process of Photosynthesis
Photosynthesis primarily occurs in the chloroplasts of plant cells and involves two main stages:
- Light-dependent Reactions:
- Occur in the thylakoid membranes of chloroplasts.
- Chlorophyll absorbs sunlight, which excites electrons and initiates a series of reactions.
- Water molecules are split (photolysis) to release oxygen.
- Energy is captured in the form of ATP and NADPH.
- Light-independent Reactions (Calvin Cycle):
- Occur in the stroma of chloroplasts.
- ATP and NADPH produced in the light-dependent reactions are used to convert carbon dioxide from the atmosphere into glucose.
- This cycle involves three main phases: carbon fixation, reduction phase, and regeneration of RuBP.
Importance of Photosynthesis
- Oxygen Production:
- Generates the oxygen necessary for the survival of aerobic organisms.
- Food Source:
- Forms the basis of the food chain, providing energy for herbivores and subsequently for carnivores.
- Carbon Dioxide Regulation:
- Helps regulate atmospheric CO2 levels, playing a role in mitigating climate change.
Conclusion
In summary, photosynthesis is a crucial process that sustains life on Earth by converting solar energy into a usable form, producing oxygen, and supporting food webs. Understanding this process is vital for environmental science and sustainability efforts.

Answer

Photosynthesis is the process in which the plants which contain chlorophyll   make their own food with the help of sunlight,carbon dioxide and water

Answer

Photosynthesis is a chemical process through which plants make their own food from simple substances like carbon dioxide CO2 , water H2O , in the presence of sunlight and chlorophyll. The products of photosynthesis are oxygen and glucose. Glucose is stored in the form of starch in leaves.
