3) Explain giving appropriate reasoning why the neoblasts are considered the following a. A stem cell: b. Pluripotent: c. Neoblasts are the only dividing cells in the planarians body- Is this statement true or false? Justify with reasons. d. Discuss the role of neoblasts in the planarian regeneration. What would happen if all except ONE neoblast was killed by irradiation? Would the planarian be able to regenerate and build the neoblast population?

3) Explain giving appropriate
reasoning why the neoblasts are
considered the following
a. A stem cell:
b. Pluripotent:
c. Neoblasts are the only
dividing cells in the
planarians body- Is this
statement true or false?
Justify with reasons.
d. Discuss the role of neoblasts
in the planarian
regeneration. What would
happen if all except ONE
neoblast was killed by
irradiation? Would the
planarian be able to
regenerate and build the
neoblast population?
e. What role do neoblasts play
in the maintenance of the
planarian anatomy?
4) There are several other animal
models that display regenerative
properties including the zebrafish,
salamander, and hydra. What
specific strengths do planarians
offer that makes studying
regeneration feasible?|
