How the extensive regenerative power of planaria and starfish may be used as a mean of asexual reproduction
Ostrovityanka [42]
<span>Planaria have a huge regenerative power because of the presence of adult stem cells called neoblasts. If you cut Planaria into pieces, each piece can regenerate into a complete organism and that’s a form of asexual reproduction. Cells which are located on the wound site proliferate to form a blastema-mass of cell that will grow into a new organ. Those cells will differentiate into new tissues and regenerate the missing parts.</span>
<span>The similar thing is happening with starfish.</span>

ArbitrLikvidat [17]

Answer:

The new cells are the same as the previous ones, since they are the result of the mitosis process.

Explanation:

When we cut our skin, our brain sends information to millions of cells to take action and prevent this cut from putting us in danger. At that moment, the blood cells begin their work, supplying enough oxygen to stop possible bleeding and start the healing process. Then another group of cells swap out possible bacteria that may be trying to get into the wound. Last but not least, skin cells enter cell division and undergo mitosis, to generate new cells and create a new skin layer.

New cells are the same as old cells, as they are the result of mitosis. Mitosis is the process of cell division where one cell gives rise to two cells exactly the same as it.
