Question

1) wound healing in the matured
part of the secondary stem -
occurs due to
a) Differentiation b) De-dófferentiation
c) Re- differentiation a) none.​

Answer 1

Answer:

B

Explanation:

HGF accelerates wound healing by promoting the dedifferentiation of epidermal cells through-integrin/ILK pathway.

Answer 2

Answer:

Wound healing happens as a result of de-differentiation. As a result, B is right.

Explanation:

In mature stems, the activity of the secondary meristem promotes wound healing.

• Cellular dedifferentiation is a cellular process in which cells develop backwards within their own lineage, from a partly or terminally differentiated stage to a less differentiated stage.
• Dedifferentiated cells lose their capacity to divide and gain is specialisation
• RE-differentiation occurs when a de-differentiated plant cell loses its capacity to divide and regains its unique speciality.
