What are the main elements of protoplasm?

99% of protoplasm is made of 4 basic elements, i.e., oxygen, carbon, hydrogen and nitrogen Therefore; these are called major constituents of the protoplasm. 8 other elements (trace elements), present in quantities of less than 1% each, are sulphur, phosphorus, potassium, iron, magnesium, calcium, sodium and chloride.

Why protoplasm is called the physical basic of life?

protoplasm is known as physical basis of life because it is a combination of nucleoplasm and cytoplasm which make it a skeletal support for cell and the physical activity of cell is depend on it so bot he cytoplasm and nucleoplam deals with it...

What are the characteristics of protoplasm as a mixture?

The substance present between the cell membrane and the nucleus. Contains cytoplasm and the nucleus. Contains cell organelles like Golgi bodies, endoplasmic reticulum, mitochondria, ribosomes, but no nucleus. Thick, translucent fluid composed of lipids, carbohydrates, inorganic salts, and nucleic acids.

What is protoplasm briefly discuss its chemical composition and physical properties?

The dry protoplasm shows 45% proteins, 25% carbohydrates, lipids 25% and 5% other substances. Protoplasm contains varying quantities of water in different parts of an organism. There is about 80%—90% of water which is about 3 parts of the total protoplasm.

What are the two main parts of protoplasm?

The protoplasm consists of two major divisions in eukaryotes: the cytoplasm, and the nucleoplasm (cell nucleus).

What is protoplasm explain the nature and properties of it?

The protoplasm is a polyphasic colloidal system. The colloidal (Gr., kolla = glue) system of protoplasm contains abundance of water in which certain solutes remain dissolved and certain solute particles of various sizes remain suspended in it. The suspended particles may be of 0.001 µ to 0.1 diameter.

What is protoplasm and physical basis of life?

According to Huxley, the protoplasm is physical basis of life. Inside the cell wall of living cell, the living substance is known as protoplasm. The protoplasm is a thick fluid or jelly like substance.

Who defined protoplasm as a physical basis of life?

Thomas Huxley in 1869, said protoplasm is the physical basis of life. The term 'bioplasma' was created by Beale in 1872. The protoplasm was proposed by Hanstein in 1880, as the entire cell except for the cell wall.

What is commonly called the physical basis of life?

According to Huxley the protoplasm is the physical basis of life. Inside the cell wall of living cell the living substance is known as protoplasm. The protoplasm is a thick fluid or jellylike substance.

What is the composition of protoplasm?

The protoplasm is the living part of a cell, which is surrounded by a plasma membrane. It is mainly composed of a mixture of macromolecules like amino acids, ions, monosaccharides and macromolecules like proteins, polysaccharides, nucleic acids, lipids and water and inorganic salts.

What is difference between protoplasm and protoplast?

Protoplast is a naked cell in which the cell wall is removed through enzymatic degradation while the protoplasm is the collective term that is used to refer to both cytoplasm and the nucleus. This is the key difference between protoplast and protoplasm.

What is protoplasm name the four elements which make up major part of protoplasm?

These are carbon, hydrogen, oxygen and nitrogen.

Which theory is most acceptable for physical structure of protoplasm?

(5) Colloidal theory- “Fisher 1894, Hardy” 1899 and “Wilson” 1925. This is most acceptable theory for protoplasm. According to this theory, the protoplasm is a polyphasic colloidal system.

Is protoplasm a colloidal?

Protoplasm is a colloidal solution. It is a general term used for the living substance of cells which is enclosed by the plasma membrane.

Is the protoplasm homogeneous or heterogeneous?

The protoplasm, under an ordinary microscope, seems to be a clear homogeneous fluid, called hyaloplasm, in which are distributed globules, granules, and various special differentiations.
