Question

Why is cell division important for both single-celled and multicellular organisms?

Answer 1

Answer:

Because it is a mode for reproduction and growth.

Explanation:

Cell division is important for both single-celled as well as multi-cellular organisms.

In single-celled organisms, the cell division is the process which helps them to reproduce and form new organisms.

In multi-cellular organism, the cell division becomes more important because both, the division and growth in cells of multi-cellular organism occurs by means of cell division. When cells divide, the number of cells increases and it is seen as a overall growth in the organism. Damaged tissue repair is also accomplished by the cell division itself.

Answer 2

Cell division is important for both single-celled and multicellular organisms because it is the fundamental reproduction cycle of both cells.

Reproduction consists of the production of new individuals of the same species as the parent, which makes it possible to multiply and perpetuate the species.

Single-celled organisms reproduce asexually, through various processes of cell division, such as mitosis, binary fission, budding, etc.

• Cell division is fast and simple in unicellular organisms, it allows an isolated individual to perfectly give rise to new descendants, sometimes many of them, although always genetically identical to itself and to each other.

On the other hand, cell division allows the growth of multicellular organisms and the repair of tissues.

• The reproduction of the cells of the multicellular organism is constant since replacements are being generated for damaged tissues, or to fulfill specific tasks such as defensive cells.

On the other hand, the organism as a whole reproduces once it reaches maturity, certain types of reproductive cells are generated and are responsible for building a complete new individual, unlike the bipartition processes of unicellular life in which two emerge from an individual.

Therefore, we can conclude that cell division is important for both single-celled and multicellular organisms because it is the fundamental reproduction cycle of both cells.
