Question

Cell wall was discovered by:
(1) Robert brown
(2) Malpighi
(3) Robert Hooke
(4) Nageli

Answer 1

Hint In biology, a cell is a membrane-bound unit that contains the basic molecules of life and is made up of which all living entities are made up. A single cell, such as a bacterium or yeast, is frequently a complete organism in and of itself. As cells age, they develop specialised functions.

Complete answer:
The microscope opened up smaller worlds, revealing what life forms were made of, while the telescope made the Cosmos available to human observation. Robert Hooke was the first to discover and name the cell in 1665. He noticed that it appeared oddly similar to cellula, or little apartments inhabited by monks, and so the name.
However, what Hooke truly saw under the microscope were the dead cell walls of plant cells (cork). Micrographia published Hooke's description of these cells. The nucleus and other organelles found in most living cells were not visible in the cell walls discovered by Hooke.
Marcello Malpighi was an Italian biologist and physician known as the "Father of Physiology and Embryology" and the "Founder of Microscopical Anatomy and Histology."
Robert Brown was a Scottish botanist who was responsible for the discovery of the cell nucleus as well as the Brownian motion, which is the random movement of microscopic particles.
Carl Wilhelm von Nägeli was a botanist from Switzerland. He investigated cell division and pollination, but is best remembered for discouraging Gregor Mendel from continuing his genetics research.

So, the correct answer is option 1.

Additional Information
These cells work together with other specialised cells to form the foundations of huge multicellular organisms like humans and other animals. Despite being far larger than atoms, cells are nonetheless incredibly small. Mycoplasmas are a type of bacterium that are the tiniest known cells.

Note: The cell, as an isolated unit, is capable of metabolising its own nutrition, synthesising a wide range of chemicals, generating its own energy, and duplicating itself to produce future generations.
