Class 11 Biology Important Terms and Questions
What is meant by Anatomy?
It is the study of gross internal structure of organs and different parts. It ascertains the identification and similarities of one organism with other organism in the course of studies. Some organism have considerable similarities in external and internal features, where as in some organisms, there is close resemblance in external features but they differ in internal structure. For example – Man, Monkey and Dog have analogy in internal organ system but externally all of them differ from one another.
What is Cell Biology?
The body of living beings is composed of one or many cells. The structure, function and division of the cell directly determines the life activities of living beings. All researches or studies related to cell are included under the branch known as Cell Biology. It involves the studies of all kinds of cells and their behaviour.
What do you know about Molecular Biology?
The cell consists of large number of micro and macro molecules such as nucleic acids, proteins, lipids etc. The interaction between these bio-chemical molecules results into life and all these studies of cells at molecular level are included under the branch known as Molecular Biology. It involves the studies of composition and mechanism of synthesis of the biomolecules of cells.
What is Morphology?
It is the study of external features of organisms. It essentially includes the understanding and interpretation of structure both external and internal.
Branches of Biology – Taxonomy
Man has always tried to name and classify the things present in the surrounding according to their utility. This led to extensive collection of knowledge about plants and animals. At present about 1200000 species of animals and about 7 to 8 lakh species of plants are known to us. The branch of biology which deals with the identification and classification of organisms is called Taxonomy.
Branches of Biology – Physiology
Plants and animals perform life processes in a similar fashion. For example digestion, respiration, excretion etc. In addition, plants also perform photosynthesis. All these life activities are the consequences of bio-chemical reactions that occur inside the cell. The detailed study of these reactions is known as Physiology. The study of life processes and functions of plants is called Plant-Physiology. Whereas study related to animals is defined as Animal Physiology.
Branches of Biology – Histology
The body of various plants and animals are composed of different kinds of organs and organ systems. These organs are formed by special structures called tissues. The tissues are the groups of such cells which are similar in structure, function and origin. Thus the tissues are microscopic structures and can be studied only with the help of microscope. Substantially the microscopic study of internal structure of living organism is called as Histology.
