What is photosynthesis?
Answers
Answer:
★ Photosynthesis : Photosynthesis is a process by which phototrophs convert light energy into chemical energy.
★ The word 'photosynthesis' is derived from Greek word phos and synthesis. Phos means "light" and synthesis means "combining together" . This means that combining together with the help of light.
★ Photosynthesis also applies to other organisms besides green plants. These includes several prokaryotes such as cyanobacteria, purple bacteria and green sulfur bacteria .
★ Photosynthesis is also used by algae to convert solar energy into chemical energy.
★ Photosynthesis occurs when plants use light energy to convert carbon dioxide and water into glucose and oxygen.
★ Chloroplasts are the sites of photosynthesis.
★ Factors affecting photosynthesis :
- Light intensity - Increased light intensity results in a higher rate of photosynthesis .
- The concentration of carbon dioxide - Higher concentration of carbon dioxide helps in increasing the rate of photosynthesis.
- Temperature - for photosynthesis, it is important to have temperature between 25° to 35° C
- Water - Water is an important factor in photosynthesis, its deficiency can lead to problems in the intake of carbon dioxide.
Answer:
photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy through the cellular resipriaption can later be released to fuel the organism metabolic activities
