Answer:

Hugo von Mohl

Explanation:

Hugo von Mohl

…plant cells, the German botanist Hugo von Mohl coined the word protoplasm to designate

As a result of his studies on the plant cell, von Mohl developed the idea that the nucleus of the cell was within the granular, colloidal material that made up the main substance of the cell. In 1846 he named this substance protoplasm, a word that had been invented by the Czech physiologist Jan Evangelista Purkinje with reference to the embryonic material found in eggs. Von Mohl was also first to propose that new cells are formed by cell division, a process he observed in the alga Conferva glomerata. In 1851 he proposed the now-confirmed view that the secondary walls of plant cells have a fibrous structure.

Theorizing on the nature and function of plastids (small bodies within specialized cells), von Mohl provided the first clear explanation of the role of osmosis (passage of a substance through a membrane from a region of higher to one of lower concentration) in the physiology of a plant and was one of the first to investigate the phenomenon of the movement of stomatal openings in leaves.

Protoplasm, the cytoplasm and nucleus of a cell. The term was first defined in 1835 as the ground substance of living material and, hence, responsible for all living processes. Advocates of the protoplasm concept implied that cells were either fragments or containers of protoplasm. The weakness of the concept was its inability to account for the origin of formed structures within the cell, especially the nucleus. Today the term is used to mean simply the cytoplasm and nucleus. The word protoplasm is somewhat unpopular in modern biology, although the term protoplasmic streaming is commonly used to describe the movement of the cytoplasm.
