Question

1. why do we have many tiny cells rather than fewer larger ones? 2. explain the importance of the cell cycle to the growth of organisms and repair of cells.

Explanation:

Answer:

1. Smaller cells have a larger surface - area - to - volume ratio, which allows for more efficient exchange of materials like nutrients and waste between the cell and its environment. Larger cells would have a relatively smaller surface - area - to - volume ratio, making it difficult to meet their metabolic needs.
2. The cell cycle is important for the growth of organisms as it allows for the production of new cells, increasing the number of cells in an organism. For cell repair, damaged cells can be replaced through the process of cell division in the cell cycle. New cells can take the place of old or damaged ones, maintaining the normal functioning of tissues and organs.
