protoplasm, the cytoplasm and nucleus of a cell. Today the term is used to mean simply the cytoplasm and nucleus. ... The word protoplasm is somewhat unpopular in modern biology, although the term protoplasmic streaming is commonly used to describe the movement of the cytoplasm.

Why is protoplasm important to us?
What is the primary function of protoplasm? Protoplasm contains the genetic material of a cell. It also controls the activity of the cell.
Who is the scientist of protoplasm?
In the year 1835, The Dujardin first discovered the protoplasm and he was named as “sarcode”. J.E. Purkinje (1839) – first introduced/coined the term 'Protoplasm'.
Why protoplasm is the physical basis 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 is protoplast in biology?
Protoplasts are spherical naked plant cells produced by the removal of the cell wall with digestive enzymes (Fig. 1). They are usually derived from either leaf tissue or from cell suspension cultures and have been isolated from a wide variety of plant species.
What is protoplasm theory?
According to the protoplasmic theory given by Max Schultze, all the living matter, of which the plants and animals are formed, is formed from the protoplasm. He also defined a cell in terms of protoplasm as 'a mass of protoplasm with or without a cell wall'.
What is the meaning of cytoplasm in science?
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. ... All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.
What is the discovery of protoplasm?
In the year 1835 Dujardin discovered the protoplasm and named as “sarcode”.J.E. Purkinje (1839) – first introduced the term 'Protoplasm'. In eukaryotes, the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm. So, the correct answer is 'Dujardin'.
Is protoplasm and cytoplasm same?
While Cytoplasm is surrounding the nucleus in a cell. The cytoplasm contains organelles, Cytosol, enzymes, proteins Whereas, the Protoplasm contains Cytoplasm and nucleus. The cytoplasm is composed of water, salt, and protein whereas the Protoplasm is composed of liquids, carbohydrates, proteins, and a nucleus.
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 and its function?
what is the function of protoplasm? Protoplasm contains the genetic material of a cell. It also controls the activity of the cell. The first component of the protoplasm is the cytoplasm, which in eukaryotes exists between the cell membrane and the nucleus.
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 is surrounded by the membrane of the cells.
How does protoplasm occur in plants?
In plant cells the protoplast, or living material of the cell, contains one or more vacuoles, which are vesicles containing aqueous cell sap. Plant cells are also surrounded by a relatively tough but elastic wall. Water entering the vacuole by osmosis (i.e., movement of water across a membrane from…
How is protoplast formed?
Protoplasts are isolated cells produced by removing the surrounding cell wall either by mechanical means or by the use of cell wall degrading enzymes. Removal of the cell wall leaves the protoplast surrounded by the plasmalemma membrane.
What is protoplasm Class 9?
Protoplasm refers to the living, semi-transparent fluid content surrounded by the plasma membrane. It is composed of the mixture of micro and macronutrients such as ions, amino acids, monosaccharides, polysaccharides, water, nucleic acid, proteins and lipids.
