Question

BlackTom AI · Accepted Answer

The question asks for the specialized cell type required for planarian regeneration.
Neoblasts are the pluripotent stem cells in planarians that drive regeneration and tissue renewal. They are capable of dividing and then differentiating into the various cell types needed to replace lost or damaged tissues, which is essential for the planarian’s remarkable regenerative abilities.
If a student encounters a lack of answer choices, it can be helpful to connect the term to its functional role: neoblasts provide a reservoir of undifferentiated cells that respond to injury by proliferating and then repopulating the damaged area with appropriate cell types. This concept underpins why planarians can regenerate entire bodies from small fragments.
A potential misconception would be to confuse neoblasts with differentiated cell types or with cells associated only with early development; however, neoblasts remain undifferentiated and highly proliferative, enabling regenerative processes throughout the organism's life.
Another point to consider is that the term is sometimes written with different capitalization (neoblast vs. Neoblast) depending on text conventions, but the biological meaning remains the same: a pluripotent regenerative stem cell in planarians.
