Chapter   1: The Living World

1.1   What is 'living'?  1.2  Diversity in the living World   1.3  Taxonomic Categories 1.4  Taxonomical Aids

How wonderful is the living world! The wide range of living types is amazing. The extraordinary habitats in which we find living organisms, be it cold mountains, deciduous forests, oceans, fresh water lakes, deserts or hot springs, leave us speechless. The beauty of a galloping horse, of the migrating birds, the valley of flowers or the attacking shark evokes awe and a deep sense of wonder. The ecological conflict and cooperation among members of a population and among populations of a community or even the molecular traffic inside a cell make us deeply reflect on -what Indeed is life? This question has two Implicit questions within it. The first is a technical one and seeks answer to what living is as opposed to the non-living, and the second is a philosophical one. and seeks answer to what the purpose of life is. As scientists, we shall not attempt answering the second question. We will try to reflect on -what is living?

What is EcoRI?

  What is EcoRI? EcoRI is a restriction enzyme or restriction endonuclease. It cuts the DNA double helix at a specific site. This restriction enzyme was first isolated from  E.coli.  These restriction enzymes derive their names from the organisms where it was first isolated from. Similarly, another restriction enzyme was named HindIII as it was isolated from  Haemophilus influenzae. Here Eco refers to  Escherichia.coli.  R is for the strain RY13 and I (one) as it was the first enzyme to be isolated from the given strain. So EcoRI is pronounced as Eco-R-One. Restriction enzymes present in bacteria are a defence mechanism to protect against bacteriophage. Due to methylation, bacterial DNA remains unaffected. Read on to know more about EcoRI. Key Features of EcoRI EcoRI was discovered in Herbert Boyer’s lab. It is a type II restriction enzyme, which cuts specifically at the restriction site having 5’-GAATTC-3’ sequence. It cuts the DNA at a specific site formi...

  When it comes to human beings, it is all the more difficult to define the living state. We observe patients lying in coma in hospitals virtually supported by machines which replace heart and lungs. The patient is otherwise brain-dead. The patient has no self-consciousness. Are such patients who never come back to normal life, living or non-living?   If we define coma patient under living category, which of the following will not be a supporting feature to him or her? a. Metabolism b. Self-consciousness c. Cellular organization d. Both a and c b     Which one of the following aspects is an exclusive characteristic of living things? (Mains 2011) (a) Isolated metabolic reactions occur in vitro (b) Increase in mass from inside only (c) Perception of events happening in the environment and their memory (d) Increase in mass by...

  Perhaps, the most obvious and technically complicated feature of all living organisms is this ability to sense their surroundings or environment and respond to these environmental stimuli which could be physical, chemical or biological. We sense our environment through our sense organs. Plants respond to external factors like light, water, temperature, other organisms, pollutants, etc. All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues. Photoperiod affects reproduction in seasonal breeders, both plants and animals. All organisms handle chemicals entering their bodies. All organisms therefore, are 'aware’ of their surroundings. Human being is the only organism who is aware of himself. i.e., has self-consciousness. Consciousness therefore, becomes the defining property of living organisms.   The most obvious and technically complicated feature of all living organisms would be- a. Sensing sti...
