Question

The term protoderm was coined by
A. Haberlandt
B. Nageli
C. Hanstein
D. Schmidt

Answer 1

He was an Austrian botanist. He was the child of European 'soybean' pioneer Professor. His child Ludwig was an early conceptual physiologist currently given credit as the 'granddad' of the contraception pill. The essential meristem in vascular plants that offers ascend to epidermis. Additionally called dermatogen.

Complete answer:

Haberlandt previously called attention to the conceivable outcomes of the way of life of confined tissues, plant tissue culture. He recommended that the possibilities of individual cells through tissue culture and furthermore proposed that the corresponding impacts of tissues on each other could be dictated by this strategy. Haberlandt's unique attestations strategies for tissue and cell culture have been acknowledged, prompting critical revelations in Biology and Medicine. His unique thought introduced in 1902 was called totipotentiality: "Hypothetically all plant cells can offer ascent to a total plant”.
A meristem (meristematic tissue) is a plant tissue that is composed of undifferentiated, effectively isolating cells. Its basic capacity is development. A portion of the cells keep on offering ascend to new cells by cell division while others form into separated cells containing a specific lasting tissue (for example epidermis, trichomes, phellem, vascular tissues, and so on) There are two kinds of meristems dependent on the sort of development they are related with. They are the essential and the optional meristems. The essential meristem is the kind of meristem answerable for the essential development of the plant. It represents the expansion long or stature. A case of an essential meristem is the apical meristem. It is a meristem that is situated at the tips or apices of a plant. In this way, it is found especially in the root peak and the shoot zenith. In vascular plants, the apical meristem may form into the protoderm, the procambium, and the ground meristem. The meristem that offers ascend to epidermis, specifically, is alluded to as the protoderm. It is situated around the outside of the stem.

So, the correct option: - (A) Haberlandt

Note: Essential development started by apical meristems close to tips of roots and shoots produce essential tissues that are halfway separated into ground meristem that produce ground tissue protoderm that produce epidermis and procambium that produce essential vascular tissue. This hypothesis was given by Haberlandt.
