Plants require energy to grow and thrive in their environment, and the process of cellular respiration allows plants to break down glucose into ATP, which provides energy they need to carry out various functions.
<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>
