THE LIVING WORLD
1.Increase in mass and increase in number of individual are the twin characteristics of growth .All living organisms grow .
2 Multicellular organism grow by cell
division.
3 In plants growth by cell division occur throughout their life span .In animals growth is seen only up to a limited time.
4 Unicellular organisms grow by cell division.
5 Reproduction is a basic feature of living organisms
6 Fungi multiply and reproduce through asexual spores.
7 In planaria reproduction is through true regeneration .Unicellular organisms like bacteria , algae and amoeba reproduce through cell division as well.
8 Some organisms such as mules , sterile , worker bee , infertile human couple does not undergo reproduction.
9 All living organisms are made up of chemicals. These chemicals ,big or small, belong to various class , size ,function etc. They are constantly made and converted into other bio -molecules. These conversions are called metabolic reaction. The sum total of all metabolic reactions are called metabolisms. It is exhibited by all living organisms including plants ,animals ,fungi etc.
10 Cellular organization is a defining feature of living organisms.
11 All living organisms have the ability to sense their environment and respond to these environmental stimuli which can be physical ,chemical or biological.

12 Plants respond to external stimuli such as light, water, temperature, pollutants etc.
13 All living organisms are aware of their surroundings. Human beings are the only organism who is aware of himself ie has self consciousness. Consciusness is a defining feature of all living organisms.
DIVERSITY IN THE LIVING WORLD
14The number of species that are known and described range between 1.7 to 1.8 million. Biodiversity is the number and type of organisms present on the earth.
14 There is a need to standardize the naming of living organisms such that a particular organisms is known by a single name. This process is known as nomenclature.
15 Nomenclature or naming is possible when organisms are described correctly.
This is identification.
16For plants, scientific names are based on agreed principles and criteria , which are provided in international code for botanical nomenclature[ICBN].
17Animal taxonomists have evolved international code of zoological nomenclature [ICZN].
18 The scientific names ensure that each organisms has only one name.
19 Each name has two components –the generic name and the specific epithet. This system of providing a name with two components is called binomial nomenclature .
20 This naming system given by Carolus Linnaeus is being practiced by biologist all over the world . This naming system using a two word format was found convenient.
21 The scientific name off mango is written as Mangifera indica.
22 Mangifera represents the genus while indica represents the specific epithet.
UNIVERSAL RULES OF NOMENCLATURE
01 Biological names are generally in Latin and written in italics.
02 The first word in a biological name represents the genus while the second component denotes the specific epithet .
03 Both the words in a biological name , when hand written , are separately underlined or printed in Italics.
04 The first word denoting the genus starts with a capital letter while the specific epithet starts with a small letter.
The Dissertation on The Research Process Scientific Method
Processes of research by Jonathan Guy In this essay I will outline the primary methods of conducting research, their advantages and disadvantages and will outline where they are best utilised. In addition to this, I will select certain methods of research that I believe will be applicable to my own dissertation and state why I will use those particular methods to conduct my own research. The first ...
CLASSIFICATION
23 Classification is the process by which anything is grouped into convenient categories based on some easily observable characters .
24 Dogs , cats, mammals, wheat, rice, plants, animals, etc are convenient categories we used to study organisms .The scientific term for these categories is taxa.
25 Based on characteristics , all living organisms can be classified into different taxa. The process of classification taxonomy.
26 Characterization , identification , classification and nomenclature are the process that are basic to taxonomy.
27 The branched of study referred to as systematics deals with different kinds of organisms and their diversities but also the relationships among them.
28 Systematics takes into account evolutionary relationships between organisms.
