Which of the following is true of morphollactic regeneration in hydra?

Cells need to proliferate to regeneration new tissues and structures

Wnt3 is the apical organizer and is necessary for formation of the hypostome (head structure).

When cut in half, the foot half can regenerate but not the head half

When cut in half, the head half can regenerate but not the foot half

Answer #1

Answer :) First Option

The first option is the correct answer. The body of hydra is regulated by morphogenetic gradients, which determine the location of the head and foot. Hydra has three types of stem cells that can differentiate to all types of cells of a hydra. Therefore, cells of Hydra can develop new tissue and Head and foot structures of its body. If a hydra is cut in half, the head half regenerates a fresh basal disc, and the foot half regenerates a new head.
