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 fixes the proof and parallel of organisms in the course of study. In some organism, there is close identity in external features. They differ in internal structure. Example: Man and Monkey have symmetry in internal organ system. Their outer bodies look different.
What is Cell Biology?
The body of living things formed by one or many cells. The shape, work, division of the cell, tells the life activities. All study related to cell are 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 contains large number of micro and macro molecules. Such as nucleic acids, proteins, lipids etc. The relation between these bio-chemical molecules results into life. All the studies of cells are includes under the one branch. We know this as Molecular Biology.
What is Morphology?
This is the study of outer features of living being. It includes forms both outer and inner.
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.
