organs of a plant body with functions

Summary - The cells of all living organisms consist of protoplasm, which is bound by a cell membrane. Prokaryotic cells and cells of algae, fungi and higher plants contain a cell wall outside the cell membrane. Some protozoans cells show the presence of a cell coat outside the c..

Every organism, whether its body is unicellular or multicellular, is capable of performing all vital functions such as respiration, ingestion, excretion and reproduction. In multicellular organisms, because of the increase in body size, it is ..

Introduction - The study of world of life is as old as man itself. All living organisms are made up of a few elements which are repeated in each of them. The basic unit of life - cell, is a structural and functional entity of life. Of all the environmental factors that affect ..

A tissue is an aggregation of cells that have a common origin and structure, and perform similar functions. Tissues are meant for meeting the physical and physiological needs of the plant body..

Nutrition - Nutrition can be defined as the process by which an organism obtains food which is used to provide energy and materials for its life sustaining activities. Thus the term nutrition includes the means by which an organism obtains its food and also the processes by whic..

Why are Organisms Composed of Cells? - All living organisms are composed of structural and functional units called cells. The body of a living organism may be composed of a single cell - as in unicellular organisms or many cells - as in mu..

The different types of cells in the body of a multicellular organism are specialised for different functions. Yet, we see an autonomy in the cells in carrying out some of the fundamental biological processes such as respiration, utilisation of food energy, synthesis of..

There are some structures in the body of organisms, which have no apparent use. Such structures are described as 'vestigial'. Vestigial organs indicate that they must have been present in a form in which they were highly functional in the ancestral forms. Th..

A section taken through any region of a typical plant body shows the presence of three tissue systems, namely Epidermal tissue system Ground tissue system and Vascular tissue syst..

Gives mechanical support to the plant by giving rigidity, flexibility and elasticity to the plant body..
