Cell cycle and Cell division

By | August 31, 2021

All the living organisms, even the enormous ones, start their journey from a single cell. The process through which cells originate from existing living cells is called as cell division. Each cell have the ability to divide into two daughters cells (In mitosis), which again can grow and divide. This after many cycles (of growth… Read More »

What are prokaryotes ?

By | August 18, 2021

All the living organisms on this planet are made up of cells. They can be divided into two groups : Prokaryotes and Eukaryotes. Prokaryotes are single celled or colonial organisms, where the cell is surrounded by cell membrane or plasma membrane and lacks a defined nucleus (as found in eukaryotic cell). These cells are of… 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 »

Endoplasmic Reticulum – The Lipid and Protein Processing Machinery of the Cell

By | July 23, 2021

The endoplasmic reticulum (ER) is divided into – smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). ER consists of a system of membranes that enclose a space or lumen, that separates it from the cytosol. The composition of the luminal or cisternal space inside the ER membranes is quite different from the cytosolic space.… Read More »

Structural and functional unit of life – The Cell

By | July 12, 2021

Our earth is a wonderful place where many different kinds of organisms co-exist. The diversity observed among living forms is huge- ranging from minute Algae to tall trees, micro organisms like bacteria to gigantic Blue whales. The thing that unifies all of them is that all have a basic unit of life called as “Cells”.… Read More »
