What is protoplasm and why it is important?
Protoplasm refers to the living substance which makes up a cell. Biologists tend to speak about the cell nucleus and the cytoplasm. It is surrounded in plant cells by a cell wall. The entire cell of animal cells is made of protoplasm, surrounded by a cell membrane.
Is protoplasm suspended?
It is generally admitted that protoplasm is a watery solution which contains dissolved in it salts and perhaps carbohydrates. The proteins are in a state of colloidal solution, but not completely so, for many of the granules found in protoplasm are doubtless protein and these are in suspension.
What does protoplasm mean?
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.
What is protoplasm Class 8 Ncert?
Answer: Protoplasm is the entire content of a living cell. It includes the cytoplasm and the nucleus of a cell.
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. The cell membrane encloses the protoplasm.
What does Protoplasm mean?
Are protoplasm and cytoplasm same?
The difference Between Cytoplasm and Protoplasm are almost minimal and both terms are used interchangeably. But for academic purposes, Cytoplasm is all the contents inside the cell membrane excluding the nucleus. And protoplasm includes cytoplasm, plus, the nucleus of the cell.
What are the two main parts of protoplasm?
– The protoplasm is bounded by a cell membrane from all sides. – 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 cytoplasm?
The Difference between Cytoplasm and Protoplasm is that protoplasm constitutes everything in the cell including the cytoplasm and nucleus while cytoplasm constitutes all parts of the cell excluding the nucleus. The organelles, ions, molecules and water portion of the cell is contained in the protoplasm so this is where everything takes place.
Does protoplasm contain a cell membrane?
The protoplasm is composed of the nucleus, cell membrane , and the cytoplasm. Therefore, cytoplasm is a part of the protoplasm. This is why the names of these two components are often used interchangeably.
What does protoplasm contain?
Protoplasm is the jelly-like complex cell mass in which numerous biological and chemical activities take place in a living cell. Hence, it is the living part of the cell and the physical basis of life. Generally, protoplasm contains 70 % to 90 % water, and the rest are mineral salts, proteins, carbohydrates, and lipids.
