What percentage of protoplasm is water?
What percentage of protoplasm is water?
• Percentage of water in protoplasm The approximate percentage of water in protoplasm is about 85% to 90%. The water forms the dispersion medium in which other elements lie suspended. water is free water in which various inorganic substances and organic compounds are found dissolved.
What is protoplasm made up of?
The protoplasm is the living material of the cell. It is primarily composed of biomolecules like nucleic acids, proteins, lipids, and carbohydrates. It also holds inorganic salts and molecules of water. The protoplasm consists of two major divisions in eukaryotes: the cytoplasm, and the nucleoplasm (cell nucleus).
What is not found in protoplasm?
Protoplasm Vs Cytoplasm 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 the maximum part of protoplasm?
Protoplasm in living beings is made up of about 75–80% water. However, this is rather misleading because the cytoplasm is full of structures called organelles, which do various tasks. The endoplasmic reticulum is the largest of these structures; there are many other organelles.
Why is protoplasm made of water?
Due to its colloidal-gel properties, the protoplasm is elastic. Since water is the disperse phase, making up 85-90% of the total protoplasm, the quantity present markedly affects these colloidal properties.
Who invented protoplasm?
Hugo von Mohl
…plant cells, the German botanist Hugo von Mohl coined the word protoplasm to designate……
Who is the father of protoplasm?
Dujardin (1835) – discovered the protoplasm and named as “sarcode”. J.E. Purkinje (1839) – first introduced the term ‘Protoplasm’.
Who named protoplasm?
The word protoplasm was coined by Hugo von Mohl in order to designate certain active contents of the vegetable cell. fifty years after its discovery by Drebbel.
What is the longest cell in the human body?
nerve cell
Complete Answer: – In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.
What makes up 99 percent of the protoplasm?
Although the protoplasm is different, however, is 99 percent of its content consists of carbon, hydrogen, oxygen and nitrogen with traces of many other elements. It is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules (nucleic acids, proteins, lipids and polysaccharides).
What is protoplasm made of inside a cell?
Protoplasm is everything inside a cell. Cytoplasm is everything outside a nucleus inclusive of organelles, enzymes and hormones. Nucleoplasm is everything inside a nucleus. 9 lessons from millionaires who are good with money.
Which is the second part of the protoplasm?
The nucleus is the second part to make up the protoplasm. It contains a cell, or organism’s genetic material. It also has a role to play in controlling cell activity. In addition, the nucleus is the place where ribosomes are produced, which are essential for the creation of proteins in the cell
Who was the first person to use the term protoplasm?
In 1880, term protoplast was proposed by Hanstein (1880) for the entire cell, excluding the cell wall, and some authors like Julius von Sachs (1882) preferred that name instead of cell. In 1965, Lardy introduced the term ” cytosol “, later redefined to refer to the liquid inside cells.

What is the role of water in the protoplasm?
Water constitutes about 65 to 80 per cent of the protoplasm. In the protoplasm, the water occurs in two forms, viz., free water and bound water. The 95 per cent of the total cellular water is used by the protoplasm as the solvent for various inorganic substances and organic compounds and is known as free water.
What makes up the protoplasm and the nucleoplasm?
The protoplasm is primarily made of water along with various ions, proteins, and carbohydrates dissolved in it. Very specialized operations occur inside the nucleus, which require a different type of protoplasm. The nucleoplasm is composed of water, dissolved ions and a mixture of other molecules.
Where do the minerals occur in the protoplasm?
In the protoplasm the minerals usually occur in the form of salts and in combination with the organic compounds. The mineral salts occur in the form of ions in the protoplasm. An ion is an atom or group of atoms which carries one or more positive or negative charge.
