In this article we will discuss about the Principle or Law of Limiting Factors. Optimum value of a factor is never constant. It depends upon the magnitude of other factors. We may continue to increase the magnitude of one or more factors without influencing the rate of reaction. In such cases it is found that a factor called limiting factor [...]
The following points highlight the two types of Photophosphorylation. The types are: 1. Cyclic Photophosphorylation and 2. Non-Cyclic Photophosphorylation. Type # 1. Cyclic Photophosphorylation: It is a process of photophosphorylation in which an electron expelled by the excited photo-centre is returned to it after passing through a series of electron carriers. It occurs under conditions of low light intensity, wavelength [...]
The following points highlight the two main types of photosynthetic pigments. The types are: 1. Chlorophylls 2. Carotenoids. Type # 1. Chlorophylls: They are the green photosynthetic pigments. Five types of chlorophylls occur in plants other than bacteria— a, b, c, d and e. Out of these only two chlorophylls occur in the chloroplasts of higher plants, a and b. [...]
