Question

Bacterial photosynthesis vs plant photosynthesis

Answer 1

Plant Photosynthesis

1. Plants contain definite chloroplasts

2. In plants photosynthesis, the pigments involved are chlorophylls, caretonoids and phycobilins



3. It takes place at  wavelengths between 400 to 700 mμ

4. The CO2 reductants is NADPH + H+

5. The electron donor in this is only H2O

6. Oxygen is evolved

7. Two pigment systems are involved

8. The reaction centre of PS I is P700 and of PS II is P673 or P680

9.  Non cyclic photophosphorylation is dominant

10. Emerson’ s enhancement effect occurs.

Bacterial Photosynthesis

1. Bacteria lack definite chloroplasts

2. In bacterial photosynthesis, the pigments involved are bacterio-chlorophylls, bacterioviridin and open chain aliphatic carotenoids.



3. It takes place at wavelengths above 700 mμ

4. The reductants is NADH + H+

5. The electron donors in this are H2S, inorganic compounds and reduced organic compounds

6. Oxygen is not evolved

7. It involves only one pigment system

8. The reaction centre is only P890

9. Cyclic photophosphorylation is dominant

10. Emerson’ s enhancement effect occurs is not reported.

Answer 2

Answer:Plants use water and carbon dioxide to conduct photosynthesis. Except forcyanobacteria, photosynthetic bacteria cannot process water. Instead, they use inorganic or organic molecules they find in their environment, such as hydrogen sulfide and sulfur compounds. ... Plants contain definite chloroplasts, bacteria don't.
