In this article we will discuss about the roles of micronutrients elements in plants. 1. Manganese: Manganese is required in very low concentrations as its high concentrations become toxic to plants. It is abundant in the physiologically active parts of the plant especially leaves and it is relatively immobile. It is an activator of enzymes involved in respiration and nitrogen [...]
In this article we will discuss about the role of dark-fixation of CO2 in plants. In several plants a highly specialized cellular adaptation in most of the developmental systems exists in which dark-fixation of CO2 utilizes phosphoenolpyruvate (PEP) derived from carbohydrates as a substrate plays a vital role (Fig). Malate produced from dark fixation of CO2 acted as an osmoregulatory [...]
In this article we will discuss about the role of Phytochemistry in systematic botany. Phytochemistry (plant chemistry) also plays an important role in systematic botany. This is based on the assumption that related plants have a similar chemistry. For example, In Lichens chemical methods are used for identification of genera and species. But there is a controversy between Taxonomists as [...]
