Identify
the correct match of the modes of regeneration (column I) with their definition
(column II)
|
Column I |
Column II |
|
A. Stem
cell-mediated regeneration |
i. Through
the re-patterning of existing tissues. There is often little new growth but
rather cell death and a change in cell type (i.e., transdifferentiation into
a different cell fate). This results in a rescaling of the whole organism as
well as regeneration of the missing part. |
|
B. Epimorphosis |
ii. The
differentiated cells divide but maintain their differentiated functions. The
new cells do not come from stem cells, nor do they come from the
dedifferentiation of adult cells. |
|
C. Morphallaxis |
iii. Adult
structures can undergo dedifferentiation to form a relatively
undifferentiated mass of cells (a blastema) that then redifferentiates during
morphogenesis of the new structure. |
|
D. Compensatory
regeneration |
iv. Stem
cells allow an organism to regrow certain organs or tissues that have been
lost. |
