The following points highlight the four main raw materials used in photosynthesis. The types are: 1. Carbon Dioxide 2. Water 3. Light 4. Chloroplasts. Raw Material: Type # 1. Carbon Dioxide: In land plants, carbon dioxide is obtained from the atmosphere through the stomata. Small quantities of carbonates are also absorbed from the soil through the roots. Hydrophytes get their [...]
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, [...]
