They need to reproduce,increase in size. Also need to repair damaged cells
because we need to develop and growth. without cell division, we remain single-celled and we won't grow.
A multicellular organism can not rely on glycolysis alone for energy because glycolysis is just one step in respiration. Glycolysis alone does not produce the amount of oxygen that a multicellular organism needs.
cell division is how organisms grow.
A cat is multicellular. Multicellular organisms have more than two cells. A multicellular organism is one that can be seen without the need of a microscope.
No. You need cell division to grow, and since men and women both grow from infancy until death, (eg. gaining muscle, reforming broken bones, etc.) we both need cell division.

cells in a multicellular organism have the ability to specialize in certain functions for the overall success of the organism. some genes will be expressed in some cells while other genes in other cells. this creates the difference between skin cells versus liver or blood cells. a unicellular organism must cover all the functions of an entire organism and all the necessary genes must be expressed plus all the functions of created and breaking down compounds necessary for growth, development and producing offspring.
The main distinction between unicellular and multicellular is the number of cells. Unicellular organisms survive on a single cell while multicellular means that they need a number of cells to survive.

Cells need to divide to grow, repair damaged tissues, and replace old or dying cells. Cell division allows for the distribution of genetic material to new cells, ensuring the continuity of life. Without cell division, multicellular organisms would not be able to develop, maintain, or regenerate their tissues and organs.

Cell specialization is necessary to support multicellular life because multicellular organisms need different tissues. This means it needs cells to make up those tissues and perform different functions.

no very cell need nutrients and expells but homeostasis is primitive in case of unicelluar organism
Unicellular organisms and multicellular organisms both contain the characteristics of life. Furthermore, both unicellular organisms and multicellular organisms follow the same genetic code and even contain the same organelles.
Multicellular organisms require specialized organs and systems because in multicellular organisms, different jobs are done by different cells that are specialized, e.g. A blood cell carries oxygen. A nerve cell sends and receives signals. In multicellular organisms different functions are divided among different cells. The cells in multicellular organisms are organized in ways the enables them to survive and reproduce. For any multicellular organism to survive, different cells must work together. The right type of cell must be in the right place to do the work that need to be done.
