Lets Take a Journey to the understanding of the Glowing Bird

OK, guys by now we all have watched Journey to the Center of the Earth, and we are wondering about that glowing bird we saw. 

Well I am here to help.

The bird in the movie was called Cyanis Rosopteryx.  Many people believe this bird is fake whereas some believe it sits fossilized in a museum, you choose for yourself what to believe. Me I am more fascinated by the feature on the bird that made him glow.Cyanis Rosopteryx

Lets get cracking. The reason for this phenomenon is called Bioluminescence .

Bioluminescence is simple light produced by a chemical reaction which originates in an organism. It is more commonly found in marine organisms. This chemical reaction takes place when an enzyme called luciferase, it stimulates a reaction between oxygen and a molecule called luciferins, that reaction results in the emission of light as well as inactive oxyluciferin.

The emission of light is used by many organisms such as:

  1.  Anglerfish – uses bioluminescence as a lure to attract prey.
  2. Dinoflagellates – use it as a defense against predators.
  3. Fireflies – use it to attract mates.
  4. Squids (some) –  use it as a distraction to get away from predators.

So we now know that the glowing light is called Bioluminescence and that it is a chemical reaction that takes place in an organism.


So guys what you think? Do you believe it had a bird 150 million years ago who could have been bioluminescent ?



What are Carbohydrates?
Well first to begin, Carbohydrates are called that because they are composed of carbon and water and has a composition of (CH2O)n. Carbohydrates plays many roles. They are used as an energy source, for storage, it plays a structural role and also it helps in making biological molecules. More indept:

  • Energy Source
  1. Carbohydrates belong to a group of nutrients called macronutrients. This group of nutrients are required by the body in large amounts. Carbohydrates provides the body with energy through calories and the simple sugar glucose. 
  • Storage
  1. Carbohydrates are stored in two ways in polysaccharides, STARCH & GLYCOGEN. Plants use Starch as their storage polysaccharide, Animals use Glycogen.
  2. If the body detects that there is a high concentration of glucose, the pancreas releases INSULIN , which converts glucose into glycogen and stores it in the liver and muscle.
  3. If the body detects there is a low concentration, the hormone GLUCAGON converts glycogen in the liver back into glucose to rectify this problem.

The Cell

Ok.. It was the first week of class and we discussed and learnt about CELLS. 

Firstly, WHAT IS A CELL??  Well as our Hokage correctly stated a cell is the smallest unit that is able of performing live function :

  • Growth                    cells 3
  • Replication
  • Stimulus Response
  • Metabolism

History Time: The cell was discovered by a guy named Robert Hooke in 1665. His breakthrough changed science forever. He discovered the cell, by examining a very thin slice of cork under a coarse, compound microscope and saw millions of tiny pores which he said reminded him of the wall like compartments a monk would live in. Because of that small linkage in his thoughts he decided to call them “cells.“In later years a guy named Anton van Leeuwenhoek was the first man to witness a live cell under a microscope, in 1674 described the algae Spirogyra and named the moving organisms animalcules, meaning “little animals”. Along with Matthias Jakob Schleiden, Theodor Schwann, Rudolf Virchow and Others led to the development of the Cell Theory.

The Cell Theory states:

  1. All Living Organisms are composed of cells. They may be Unicellular of Multicellular.
  2. The Cell is a basic unit of life.
  3. Cells arise from preexisting living cells.

There are two general categories of cells:

  1. Prokaryotic
  2. Eukaryotic

Prokaryotic generally means “Before The Nucleus”. As the name suggest these cells do not contain a nucleus. This is a simple cell. There are two kinds of prokaryotes Bacteria and Archaea. A prokaryotic cell has three architectural regions:

  1. Flagella and pili ( not present in all prokaryotes)
  2. Cell Envelope
  3. Cytoplasmic Region [contains cell Genome (DNA) and ribosomes]

Eukaryotic basically means “True Nucleus”. Just as the name states these cells have a nucleus. These cells are approximately 15X wider than a typical prokaryotic cell. Fungi, Protozoa, Plants, Animals, Slime Moulds and Algae are all eukaryotic.



Above is a typical comparison between a Prokaryotic and Eukaryotic cell. As seen the Eukaryotic cell is 10X the size of the Porkaryotic cell. In the Diagram, it is shown that there are many similarities between the cells such as;

  1. DNA
  2. Plasma Membrane
  3. Cytoplasm
  4. Ribosomes

After looking at the Image above you may be wondering does it have a limit to how small a cell can get or how big it can get? Well THERE IS.

The Limit as to how small a cell can be is based on the amount of DNA that is needed to make the enzymes necessary for life.

The Limit as to how large a cell can become is based on the Surface Area to Volume Ratio. Simplified  it states that as the surface area of the cell increases the Volume of that cell also increases exponentially, so much that it slows down the rate of diffusion. Thus, the cell cannot get rid of its waste fast enough or get nutrients fast enough therefore the cell will either be poisoned because of the waste or starve because a lack of nutrients.



The Summary of me

Hey whats up, my name is Rodney Mahabir, I am currently a student attending the University of the West Indies, St. Augustine Campus reading for Bsc in Biology. I am a very in the shadows person, I personally do not like to be infront for anything. I have some typical hobbies along with a weird few: Cricket, Football, Intense Gaming, Digging up in Computers and my most favorite is Martial Arts, I love it, I am into Mixed Martial Arts and also Shotokan Karate.Way Of Life My dream was to become a Doctor but to me mixing martial arts and helping people does not really seem ideal. So right now I am trying to find out what I want to do with my life, namely my purpose.

In my Degree, for this semester I have to do BIOL 1362 which is Biochemistry. My first thoughts on this subject is that it is going to be really tough, but, the lecturer for this course Jason Matthew, has made this course fun, informative and something I look forward to during the week, his method of carrying on a Tutorial is totally different, he makes it into a GAME , pitting the various benches against each other which is an unorthodox method of carrying on a class but to my surprise it really helped in the way I am learning. So far this course is my favorite, lets see if it will remain like that throughout the semester.
