Which is called the living part of a cell?

Protoplasm (/prəʊtə(ʊ)ˌplaz(ə)m/, plural protoplasms) is the living part of a cell that is surrounded by a plasma membrane. In some definitions, it is a general term for the cytoplasm (e.g., Mohl, 1846), but for others, it also includes the nucleoplasm (e.g., Strasburger, 1882).

Is a living matter of cell?

The term protoplasm was coined by J. E. Purkinje and called as protoplasm as the living matter of the cell. Protoplasm is surrounded by plasma membranes of the cell. Protoplasm is also used to define cytoplasm along with the nucleus and is responsible for all living processes of the cells.

What are protoplasmic structures?

Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes theprotoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm.

What is the process of cell reproduction called?

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

What factors initiate cell division?

Key Points

• The death of nearby cells and the presence or absence of certain hormones can impact the cell cycle.
• The release of growth-promoting hormones, such as HGH, can initiate cell division, and a lack of these hormones can inhibit cell division.

What produces energy for the cell?

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
