1) predict: what is a specific situation when an organism’s cells might need to divide? 2) how are the life cycles of cells similar to the life cycles of organisms?

1) predict: what is a specific situation when an organism’s cells might need to divide? 2) how are the life cycles of cells similar to the life cycles of organisms?

Answer

Brief Explanations:

  1. One situation is when an organism is growing. For example, a child growing into an adult requires cell division to increase the number of cells for body - size increase. Also, when an organism has an injury, like a cut on the skin, cell division occurs to repair the damaged tissue.
  2. Both cells and organisms have a life cycle with stages. Cells have a growth phase (interphase), division phase (mitosis or meiosis), and a resting or quiescent phase. Organisms have a growth phase from birth to maturity, a reproductive phase, and a senescence phase. Just as organisms reproduce to create new organisms, cells divide to create new cells.

Answer:

  1. When an organism is growing or has an injury for repair.
  2. Both have growth, reproductive - like (division for cells, reproduction for organisms), and end - like (quiescent for cells, senescence for organisms) phases in their life cycles.
