Question

Discuss the modern concept of cell theory.

Answer 1

The modern concept of cell theory concentrates on the structure and function of the organism at cellular levels. It focuses on the concept of the cell being the fundamental and basic unit of life. Also, it supports the concept of cell division, energy flow inside the cells, and the presence of DNA.

Complete answer: The Modern concept of cell theory is strongly based on the fact that all of the living organisms are products of cell arrangements. It states that all living organisms comprise cells and their products. The modern cell strongly supports the cell as the basic functional and fundamental unit of life. It briefly describes the cellular structure and compositions. According to the modern cell theory, the cell is made up of a protoplast that encloses the nucleus and organelles and is covered by a membrane. The activities of an organism are attributed to the total of the activities performed in its cellular components. Life cannot just originate innately, it needs cells to proliferate. New cells are products of pre-existing cells. Multiplication and division of cells occur in an increase in the number of cells that eventually leads to growth in an organism. The major concept of modern cell theory is that genetic information is enclosed inside the nucleus of a cell. It says that the expression, as well as management of the genetic factors, occurs inside the cell of an organism that affects the organism as a whole. These inherent traits pass from one generation to the other through chromosomes. All of the new daughter cells contain the same degree of information as in the parent cells. Also, the modern concept of cell theory focuses on the totipotency of cells. This means that cells are capable of making a whole organism unless specialized to form a specific organ or tissue.

Note: The functioning of a cell is a very complicated meshwork of thousands of processes ongoing in a small microscopic unit. New advancements in science allow scientists to discover the secrets of the cell functions. The recent topic of stem cell research opens new gates to understand the origin and the functioning of the cells.
