write a essay about living organism
Answers
Answer:
All living organisms are cellular. Cells in different organisms exhibit close similarly in structure, molecular organization and biological activities. Thus, there exists a unique master plan of organization of all cellS.All organisms have the cell as their basic structural and functional unit. Schleiden and Schwann cofounded the cell theory, according to which all living organisms are composed of one or more cells. Cells are the basic units of living organisms. All cells arise from preexisting cells.Each cell acts as a self-contained unit. It can carry out nutrition, respiration, growth, reproduction and self regulation wherever required. Isolated living cells of multicellular organisms can grow for generations artificially. Plant cells are found to be totipotent.A single cell performs all its life processes in unicellular organisms. The organelles it contains help the cell to carry out and regulate different cellular activities. But in multicellulars, there is division of labour and the cells interact and cooperate to perform different activities.........

Answer:-
THIS IS THE ESSY ON LIVING ORGANISM FOR YOU
Organization is one characteristic of life. An example of this is the levels of biological organization. The complex organization of life begins with atoms, the basic unit of matter. The atoms then combine to form small molecules and then begin to form larger molecules within a cell. Eventually the organism grow to form new populations. Each level progresses into something bigger.
The second characteristic of life is, life requires materials and energy. All living organisms require a source of energy. For plants, they require sunlight or solar energy. Animals require food for nutrients and energy. example of this is plants requiring.
Without water there would be no life on Earth; this is why water is
the most important biochemical of all.
In "Human Biology" by J.M Orten and O.W. Nevhans, it is suggested that
70% of all body weight is water, most of which is found in three major
compartments: 70% intracellular fluid, 20% interstitial fluid (lymph)
and 7% blood plasma, and only 3% in other compartments. By volume,
nearly a half of each of our organs consist of water; amounting to
approximately 10 gallons of water, of which most is in our cells.
Water is crucial for cells to function healthily and for all chemical
reactions and transport processes to occur.
Water is responsible for maintaining cell structure, aiding metabolism and helping the circulation of blood and bodily fluids; water is also responsible for removing bodily waste through excretion.
