Biology And Its Branches

-

Biology 

Definition :

Biology is the life of science the word biology comes from two Greek word "bio" mean life and "logos"study. It explorers The structures, functions and interactions of living organism.

Major fields of biology

Biology is a vast field that explores the incredible diversity of life on earth. To better understand this complexity, scientist have divided biology into three main fields.

(1)Zoology

It is study of animals including their structure function behaviour and diversity.

(2)Botany

It is study of plants including their structure growth reproduction and instructions with their environment.

(3)Microbiology

Micro the study of microorganisms such as bacteria and microscopic fungi is called microbiology it including the study of the structure function habitats and reproduction of microorganisms and their impact on health and environment.

Branches are sub- field of biology

Biology is divided into different branches to better understand the aspect of life.

Morphology 

Is the study of of the form and structure of organisms. Morphology studies the outward appearance ( shape, colour, pattern etc )as well as internal structure, like organ.

Anatomy

Is the branch of biology that explore the internal physical structure of organisms particularly humans. It helps in disease diagnosis medicals devices development and improving quality of life .For example the study of organ of the digestive system.

Physiology

Is the branch of biology that deal with the functioning of  body part. For example how the blood circulatory system transport vital substances through -out the body.

Histology

Histology is the microscopic study of tissues
 Tissues are group of cells that has similar functions. Tissue examination helps  in studies diagnosis, drug studies and understanding organ structure and function

Embryology 

Embrology is the study of process of development of organism form fertilized egg. In this branch, scientist study tissue and organ formation, identify birth defects and develop medical treatments.

Taxonomy

Taxonomy is the branch of biology that deal with the classification of organism into groups on the basis of similarities and differences. Classification of organisms help to organism and understand the diversity life identified new species and study evolutionary relationship. 

Palaeontology

Palaeontology is the branch of biology that deals with the study of fossils. The examination of fossils help scientist to know the evolutionary history of organisms. For example dinosaur  fossils provide evidence of a against reptiles that roamed the earth millions of a year ago.

Microbiology 

Microbiology deal with the study of biological molecules like carbohydrate, protein ,lipid, and nucleic acids. Molecular biology also study for fundamental life processes, 12 drugs and create a genetically modified organism.

Ecology 

Ecology is the branch of biology that deals with the relationship between organisms and their environment. Ecology helps to conserve biodiversity and address environmental problems. 

 pathology 

Is the study of diseases their causes and effects. Pathology helps in diseases diagnosis prevention and treatment. For example pathology study how the uncontrolled vision and spread of cells causes Cancer.

Pharmacology 

Pharmacology is the branch in which we study drugs and their effects on the body. This helps in the development of new drugs. For example new antibiotics are developed that are used to kill bacteria and treat bacterial infection.

Immunology 

Immunology is the branch in which we study the components of immune system and their role against diseases. Immunologist study to develop vaccines, treat auto immune disease and improve immune response to infections.

 Scientists take specific steps for doing scientific work are research. These steps are called the scientific method . For biological research these steps are called biological method. The following steps are involve in scientific method. Recognitions of a scientific problem observations ,hypothesis deduction ,experiments and results (1) Recognitions of a scientific problem  The first step involves identifying and defining a scientific problem that scientist want to investigate. Such problem is either asked by someone are comes in biologist mind by himself. For example a biologist notice that plants is an area are growing taller than usual. He develops a scientific problem. What factors are responsible for increasing growth of these plant? This problem becomes the starting point for a scientific inquiry. (2) Observation Scientist make observations about the problem. They use five senses for making observation. They also read and study the previous researches on the same are r...

 Cells are the microscopic structures that form the foundation of life. Cell are the units that carry out all the functions necessary for life. 2.1-Cell The cell is the basic unit of life. Just as bricks are the building blocks of a house cell are the building block of living organism including plants , humans and animals. Everything, from the smallest bacterium to the largest whale ,is made of cells. Most of the cell are very small and cannot be seen with the naked eye. Some cells are large enough to be seen with naked eye for example egg cell of ostrich . 2.2 structure of cell Basic structure of a cell was discovered by an English scientist Robert Hooke. In 1665 using a simple microscope ,Hooke examined as thin slices of crock and discovered tiny box like structure that he" called cell". He could not study the details of the internal structure of cell. However in the 19th century the quality of microscope improved. In 1831 while studying plant cells under a microscope, scie...

Plastid/ Golgi Apparatuse, Definition,Type

 Definition  Plastid are membrane bounded organelles present in the cell of plant and photosynthetic protist. There are three main type of plastids. Chloroplast ,chromoplast leucoplasts. Types (1) Chloroplasts Chloroplasts are the green plastid. They are present in the cell of green parts of plant and in algae they contain photosynthetic pigment for example the green chlorophyll. They carry out photosynthesis with the help of their pigments. They capture light energy convert it into chemical energy. They use this energy to prepare glucose. Like mitochondria chloroplasts are in closed by double membrane. On the internal side of inner membrane are in closed by double membrane. These stacks are called" grana". The sac- like structure which make a granum called" thylakoid". A fluid called stroma surrounding the thylakoid. Like mitochondria chloroplasts also contain DNA ribosomes. (2) Chromoplasts Are the plastids that contain pigments such as carotenoids. These pigment ...
