PHOTOSYNTHESIS IN HIGHER PLANTS (PLANT PHYSIOLOGY)

PHOTOSYNTHESIS AS A MEANS OF AUTOTROPHIC NUTRITION

Photosynthesis is a process of formation of glucose from simple inorganic substances like CO2 and H2O. There are two types of photosynthetic reaction found in nature; Dark Reaction and Light reaction.

SITE OF PHOTOSYNTHESIS

All plants are involved in photosynthesis process.The photosynthesis occur in mesophyll cells of leaves. Chloroplast is the main site where the process of photosynthesis completes by the use of inorganic compounds like Carbon-dioxide and water.

FACTOR AFFECTING PHOTOSYNTHESIS

Many external and internal factors affect the rate of photosynthesis. Some external factors are light, CO2, temperature, water, leaf anatomy and oxygen while internal factors are chlorophyll content and protoplasmic factor. Importance of factors can be demonstrated with the help of experiments.
