Where did phosphite come from? During WWII, rock phosphate was used as a white phosphorus incendiary and smoke screen. The shortage of rock phosphate concerned ag-officials and they began to look for alternative sources of phosphorus fertilizers. As a result, phosphonates were first considered as fertilizers in Germany and the United States during the 1930s and '40s. Rock phosphate is the beginning of most commercially made phosphorus products in the market today. Without the phosphate, many…

recombination events is not routinely possible in any higher plant.(3) Mosses are situated under the division Bryophyta which are non vascular plants, lacking true stems, seeds, leaves and roots as compared to Tracheophytes, (vascular plants) which contain xylem and phloem.(1) Mosses are one of the oldest groups…

INTRODUCTION Tomato (Solanum lycopersicum L.) and Potato (Solanum tuberosum, L.) are the most economically important vegetable crops in Egypt and the most widely grown vegetables in the world. The disturbance of its production affects severely it's local and export impact, because it is considered a very important consumption crop with high nutritional value and a potential export crop for the Egyptian farmers. In Egypt about 20% of total area devoted for vegetable production is cultivated…

Strawberry guava, Psidium cattleianum Sabine, is valued by the general public of Hawaii for its ornamental characteristics and fruit, which is frequently prepared into jams, jellies, juices, cakes, and pastries. However, due to false advertising and commercialization, guava as well as coffee, macadamia, passion fruit, and pineapples are seen as icons of Hawaii, yet they aren’t native to Hawaii. Even though these species aren’t native to Hawaii, coffee, macadamia, passion fruit, and pineapples do…

Photosynthesis Photosynthesis is one the most important life processes that happens on earth. It is the process plants use to create their own food by converting water and carbon dioxide into glucose and oxygen using light energy. The chemical equation for photosynthesis is 6 CO2 + 6 H2O → C6H12O6 + 6 O2. There are many things in the environment however that can help or hinder this process. In this report I will be explaining 3 structures in the leaf that allow it to carry out photosynthesis,…

Water a vital biological molecule Molecule of water Water is a substance which is transparent, odourless and colourless liquid that has a boiling temperature of 373K, freezing temperature of 273K meaning it is liquid at room temperature. Water is a compound containing 2 hydrogen atoms, but also has an oxygen molecule as well this means it has the molecular formula of H2O. The relative atomic mass of water is around 18 with “11.188% being hydrogen and 88.182% being oxygen” [1]. When bonded it…

CO2 – Good or Bad? Global warming is a very controversial topic around the world. Although it is deemed by some as a hoax or is just not real at all, it is real, and it is the single most dangerous and important issue that should be on the minds of world leaders. Global warming has several factors that contribute to its cause, but the main cause of it is the burning of fossil fuels releasing large quantities of Carbon Dioxide into our atmosphere. Carbon dioxide helps trap in heat and in turn…
