Who discovered the protoplasm?
Dujardin
Dujardin in 1835 discovered protoplasm but in 1839 it was J.E. Purkinje who coined the word protoplasm. Protoplasm is the colourless material comprising of all the living components of the cell.
What do you understand by protoplasm?
protoplasm, the cytoplasm and nucleus of a cell. The term was first defined in 1835 as the ground substance of living material and, hence, responsible for all living processes. Advocates of the protoplasm concept implied that cells were either fragments or containers of protoplasm.
What is protoplasm Class 9?
Answer: Protoplasm is the colourless liquid within a cell that comprises the cytoplasm, nucleus and organelles. Explanation: A cell is made up of a cell wall that contains protoplasm.
What is another name for protoplasm?
In eukaryotes, the portion of protoplasm surrounding the cell nucleus is known as the cytoplasm and the portion inside the nucleus as the nucleoplasm.
What is protoplasm made of?
The protoplasm is the cell’s living content. It is composed primarily of biomolecules such as nucleic acids, proteins, lipids, and carbohydrates. It also has inorganic salts and water molecules. The protoplasm is surrounded by the cell membrane.
How many types of protoplasm are there?
Protoplasm exists in three forms: in the solid state, the liquid state and sometimes in a combined solid and liquid state. The physiological state of the cell determines which form it is in at any given time.
What is the other name of protoplasm?

What is protoplasm in biology class 11?
The protoplasm contains the living material of the cell. It consists predominantly of biomolecules such as nucleic acids, sugars, proteins, and lipids. It has inorganic salts and molecules of water as well.
Why is protoplasm called a living cell?
they are together called protoplasm. nucleus acts as the boss of cell,helps in cell division, makes proteins,etc. cytoplasm contains cell organelles and cell membrane allows entry and exit of materials.so protoplasm is called’living part of the cell’. it performs funtions cell wall found in plants is dead part.
Where is protoplasm located?
It occurs everywhere in the cell. In eukaryotes, the portion of protoplasm surrounding the cell nucleus is known as the cytoplasm and the portion inside the nucleus as the nucleoplasm.
Is protoplast an animal cell?
animal cell cannot be a protoplast because the definition is saying that protoplast is present in plant cell and bacteria which have cell wall.

Which part of cell is called protoplasm?
The correct answer is Cytoplasm, nucleoplasm, and other organelles. Key Points. Protoplasm. It is the living part of the cell, which comprises different cellular organelles. It is a jelly-like, colorless, transparent, and viscous living substance present within the cell wall.
What are the main elements of protoplasm?
Protoplasmic elements carbon, hydrogen, oxygen, nitrogen, phosphorous and sulphur become constituent of protoplasmic components like nucleic acids, proteins, chlorophyll etc. Carbon, hydrogen and oxygen are the basic framework elements required for synthesis of all the biomolecules.
Where is protoplasm found?
Why cytoplasm is called protoplasm?
Protoplasm involves both the nucleus and cytoplasm. So, protoplasm = cytoplasm + nucleus. Constitution. Jelly like substance containing proteins, water, food reserves, and metabolic wastes. Protoplasm comprises carbohydrates, nucleic acid, proteins, lipids, and inorganic salts.
What is in a protoplast?
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.
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.
