Protoplasmic Factor

Introduction

The term protoplasm refers to the live elements of a cell in general. However, the term protoplasm is no longer generally used because it was initially used to describe a cell that only had two components: A nucleus and a plain, homogeneous cytoplasm.

We now understand that the cytoplasm is extremely complex and comprises numerous organelles. In eukaryotes, such as plants and animals, the protoplasm outside the nucleus is now called the cytoplasm, and the protoplasm inside the nucleus is called the nucleoplasm. The cytoplasm is the collective name for the contents of a cell in prokaryotes. 

The Components and Structure of Protoplasm

It is structurally made up of three parts: 

1) the plasma/cell membrane, 2) the plasma/cell membrane, and 3) the plasma/cell membrane.

2) Cytoplasmic fluid

3) Protoplasmic Nucleus Component

The cytoplasm, which occurs between the cell membrane and the nucleus in eukaryotes, is the most important component of protoplasm. The cytoplasm is in charge of creating an environment in which the many organelles inside it may carry out their duties. The nucleus is the protoplasm’s second component. It holds the genetic material of a cell or organism. It also plays a role in regulating cell activity. Furthermore, the nucleus is where ribosomes, which are required for the production of proteins in the cell, are created. 

Protoplasmic Characteristics

The protoplasm is the cell’s life material. Biomolecules such as nucleic acids, proteins, lipids, and carbohydrates make up the majority of them. It also contains inorganic salts and water molecules. The protoplasm is enclosed by the cell membrane. Because prokaryotes lack a nucleus and other cytoplasmic organelles, protoplasm refers to the materials enclosed within the cell membrane, i.e. the prokaryotic cytoplasm. In some prokaryotes, particularly Gram-negative bacteria, protoplasm extends to the periplasm region between the cytoplasmic membrane and the outer membrane.

Periplasm, a gel-like substance seen in Gram-negative bacteria protoplasm, is found in this location. In eukaryotes, the protoplasm is divided into two parts: cytoplasm and nucleoplasm (cell nucleus). The jelly-like substance of the eukaryotic cell is called the cytoplasm. The cytosol, vesicles, cytoskeleton, inclusions, and organelles are all present, except the nucleus. The cytoplasm of a eukaryotic cell is the space between the cell membrane and the nuclear envelope. Nucleoplasm is the substance that makes up the nuclear envelope. The nucleus protoplasm is an essential nucleoplasm. 

Protoplasm’s Functions

• It executes all of the necessary life-sustaining procedures. Biomolecules such as nucleic acids, proteins, lipids, and carbohydrates make up the majority of them. It also contains inorganic salts and water molecules. 
• The protoplasm is enclosed by the cell membrane. Because prokaryotes lack a nucleus and other cytoplasmic organelles, protoplasm refers to the materials enclosed within the cell membrane, i.e. the prokaryotic cytoplasm.
•  In some prokaryotes, particularly Gram-negative bacteria, protoplasm extends to the periplasm region between the cytoplasmic membrane and the outer membrane.

Reproduction

The protoplasm nucleus functions, for example, in the angiosperm meristematic area, when cells split to generate identical daughter cells. A cell assists in the reproduction processes of mitosis (in more evolved organisms) and meiosis (in less evolved organisms). 

Irritability

Living protoplasm responds to stimuli, such as light, which is detected by retinal cells in the eye.

Protoplasm can respond to stimuli, and it is a characteristic of life that is lost when a cell dies. 

Chemical

The majority of these functions are carried out within the cell, such as in mitochondrial respiration. Organisms require energy to carry out several chemical reactions. Plants obtain their energy through photosynthesis, whereas animals obtain their energy through respiration.

Support and Structure Some cells, such as collenchyma and sclerenchyma, give structural support, but all cells, in general, provide the structural foundation for all creatures. 

Excretion

Cells should get rid of excretory waste, which generally spreads out of the cell through the cell membrane. It necessitates the ingestion of chemicals that can be absorbed or utilised by the cells in metabolism. It is a process in which a cell extrudes material. Digestive enzymes and hormones, urine, and perspiration, among other substances, may be beneficial (secretion) or useless (excretion).

Conclusion

The protoplasm is the cell’s life material. Biomolecules such as nucleic acids, proteins, lipids, and carbohydrates make up the majority of them. It also contains inorganic salts and water molecules. The protoplasm is enclosed by the cell membrane. Because prokaryotes lack a nucleus and other cytoplasmic organelles, protoplasm refers to the materials enclosed within the cell membrane, i.e. the prokaryotic cytoplasm. In eukaryotes, such as plants and animals, the protoplasm outside the nucleus is now called the cytoplasm, and the protoplasm inside the nucleus is called the nucleoplasm.
