It can be define as the movement of the plant parts in response to the external stimulus that is contact or touch. It is also known as Haptotropism. The plant may change it's orientation, shape and size of the plant parts.

3,The thigmotropism can be positive or negative depending upon the visual response shown by the plants. The response shown by the plants is generally fast  but may be slow. This response is shown by the plants in cases of danger of herbivory.Some plants like Mimosa pudica or touch me not plant shows thigmotropism by closing their leaves on touch

Gennadij [26K]
<h2>It may become endangered </h2>

Explanation: <u><em>If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered, or extinct. Under an evolutionary phenomenon called relaxed selection, traits that were advantageous in one time and place become obsolete in another. Traits that aren't actively maintained by natural selection tend to become smaller or less functional over time, studies suggest.</em></u>

solong [7]

ANSWER:

Brain cells that are neither neurons nor glia, but which are capable of dividing and then differentiating into neurons or glia, are called NEURAL STEM CELLS.

EXPLANATION:

Neural stem cells are undifferentiated cells originating in the central nervous system.

Neural stem cells (NSCs) have the potential to give rise to the radial glial progenitor cells that grow and differentiate into neurons and glial cells.

NSCs have an important role during development producing the enormous diversity of neurons, astrocytes and oligodendrocytes in the developing CNS.

A NEURON (nerve cell) is a specialized cell that conveys electrochemical impulses throughout the body.

provide support for and insulation between them.

GLIAL CELLS are the most abundant cell types in the central nervous system. Types of glial cells include oligodendrocytes, astrocytes, ependymal cells, Schwann cells, microglia, and satellite cells.
