Factors affecting photosynthesis – Photosynthesis in plants (Part – VII)

By | October 7, 2021

In the last part of photosynthesis series , we shall look into factors governing the process of photosynthesis in plants and also importance of photosynthesis to both plants and other organisms. Earlier blogs can be read : Part I of Photosynthesis : Introduction Part II – Light Reaction PART III – Calvin Cycle Part VI –… Read More »

Comparison – C3, C4 and CAM pathways ( Photosynthesis in plants- Part VI )

By | September 27, 2021

In the previous 5 blogposts we looked into different important events taking place during the process of photosynthesis in plants. please find the links for those blogs below – Part I of Photosynthesis : Introduction Part II – Light Reaction PART III – Calvin Cycle Part VI – Differences between Light and Dark reactions or Calvin… Read More »

Photorespiration, C4 Pathway and CAM metabolism pathway – Photosynthesis in plants (Part V)

By | September 23, 2021

Evolution (cumulative changes in a population or species through time), is crucial for survival and flourishing of all species or populations. According to endosymbiosis theory, all the eukaryotic life which we see today had evolved from the Archaea bacteria. Evolution has also played an important part in process of photosynthesis- from bacteria to plants. Photosynthesis… Read More »

Difference between Light and dark Reactions – Photosynthesis in Plants Part – IV

By | September 21, 2021

Light and Dark reactions ( Calvin cycle / C3 Cycle) are sequential reactions which occur during Photosynthesis process. In this post we will look into some important differences between these two vital aspects which are essential for synthesis of food in Plants and some other organisms. Difference Light Reaction Dark or Calvin Cycle Place of… Read More »

Calvin Cycle – Photosynthesis in Plants (PART -III)

By | September 21, 2021

The term Photosynthesis was first proposed by Prof. Conway MacMillan , when he was working at University of Minnesota in 1893. In the earlier blog posts we discussed about Introduction to Photosynthesis in green Plants and details of Light Reaction. As we have seen in previous posts, Photosynthesis can be divided into two different parts… Read More »

Light Reaction – Photosynthesis in Plants (PART II)

By | September 19, 2021

Photosynthesis can be divided into two parts : Light dependent reactions or Light Reactions and Dark Reactions or Calvin Cycle. Light reactions forms the “Photo” part of Photosynthesis and Dark reactions / Calvin Cycle is a separate process which accounts for “synthesis” aspect in Photosynthesis, where sugars are produced. Light reaction involves the following events… Read More »

Photosynthesis in plants – Introduction Part I

By | September 17, 2021

Photosynthesis is a process where green plants and some other organisms (algae and some bacteria – such as Proteobacteria , Chloroflexi, Chlorobi and cyanobacteria ) uses trapped sunlight to convert carbon di oxide and water to produce chemical energy in the form of carbohydrates (most commonly glucose) and oxygen. In other words, photosynthesis is a process… Read More »

Differences between DNA and RNA

By | August 21, 2021

Nucleic acids accounts for one of the four major biological macromolecules, which carry genetic blueprint of a cell and are essential for proper functioning of the cell. Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are two important nucleic acids which help in carrying genetic information and are made up of nucleotide monomers. Even though both… Read More »

Anabolism – Building cell structures with simple molecules

By | August 7, 2021

Every living creature on this planet Earth needs to extract energy from the dietary food, a process termed as Catabolism ( breaking down of complex molecules into simpler molecules to yield maximum energy, eg: Glucose gets converted by a process involving Glycolysis, Krebs cycle and electron transport chain – to yield ATP). The opposite cellular… Read More »

Amino acids – building blocks of Proteins

By | July 31, 2021

Amino acids (aa) are the building blocks of proteins, which happens to be one of the 4 important biological macromolecules. Amino acids are organic compounds made up of nitrogen, carbon, hydrogen and oxygen, along with a variable side chain group. All amino acids share a similar fundamental structure. The central carbon atom, or also termed as… Read More »
