Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein

IMPORTANCE OF FORESTS Introduction Trees are mankind lifeline. If they are destroyed‚ there is no way that human beings can survive. From the oxygen that we breathe in‚ the food that we eat‚ to the clothes we wear‚ we owe it all to the trees. Not only this‚ trees act as purifiers of air and receptacles of our waste products. Trees have great economic value too. We get fuel‚ fodder‚ timber‚ medicines and numerous other valuable products from the trees. It is‚ therefore‚ not surprising that trees

Structure and function of macromolecules within a living organism ‘Some biological molecules in organisms are small and simple containing only one or a few functional groups‚ others are large‚ complex assemblies called macromolecules’ [1]. The term macromolecule is convenient because the bulk properties of a macromolecule differ from those of smaller molecules. These large chemical compounds have a high molecular weight consisting of a number of structural units linked together by covalent

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li

The cell is the basic unit of all life. All living things-- tigers‚ trees‚ elephants‚ and men-- are made up of cells. A cell is alive-- as alive as you are. It breathes‚ takes in food‚ and gets rid of waste. It grows and reproduces‚ or creates one of its own kind. (Garrod 36) Most cells reproduce by dividing‚ so that there are two cells where there once was one. (Akkas 78) Every living thing is made up of one or more cells‚ and each of these cells was produced by an already existing cell. New cells
