In 1825, French scientist François-Vincent Raspail became the first scientist to observe that every cell is produced through cell division. How is cell division different in single-celled organisms than in multi-celled organisms? A. Single-celled organisms duplicate their genetic material twice during cell division. B. Cytokinesis divides single-celled organisms into three daughter cells. C. There is no metaphase for single-celled organisms. D. Cell division results in reproduction in single-celled organisms.

Cell division results in reproduction in single-celled organisms. The correct option is D.

Explanation:

Single celled organism which are equally known as unicellular organisms are organisms which are made up of one cell. Due to the simplicity of the structure of these organisms, reproduction can be achieved through cell division.

Multicellular organisms as the name implies is made up of multiple cells,unlike unicellular organisms, which are to varying degrees integrated and independent.

Every cell is produced through cell division.

Cell division results to reproduction in single-celled organisms while cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring. It is also responsible for the development of a multi-celled organism from a single fertilised egg cell.

 A.

Single-celled organisms duplicate their genetic material twice during cell division

Explanation:

All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Single-celled organisms use cell division as their method of reproduction. Somatic cells contain two copies of each of their chromosomes (one copy from each parent).
