In this article we will discuss about the History and Phases of Calvin Cycle. History of Calvin Cycle: The cycle was discovered by Calvin, Benson and their colleagues in California, U.S.A. They fed Chlorella and Scenedesmus with radioactive 14C in carbon dioxide. Radioactive carbon, 14C has a half life of 5568 years. Therefore, the path of CO2 fixation can be [...]
The below mentioned article provides a study note on the C4-Dicarboxylic Acid Pathway. C4-Dicarboxylic Acid Pathway (Hatch Slack Pathway, C4 Pathway): It was worked out by Hatch and Slack (1965, 1967). However, initial discovery was made by Kortschak (1965) who found that labelled carbon dioxide (14CO2) assimilated by Sugarcane leaves first appeared in a 4-carbon compound oxalo-acetic acid (OAA or oxaloacetate). [...]
The below mentioned article provides a study note on the Seed Growth. Seed germinates to produce seedling. Seedling grows first into a juvenile plant which develops only vegetative organs. Later on it begins to produce flowers, fruits and seeds. Unlike animals, plants do not stop growing after reaching maturity. They continue to grow and bear new roots, leaves, branches, flowers, [...]
