Question

The cell, as a basic unit structure of living things, was discovered by
A. Aristotle
B. Robert Hooke
C. Schleiden and Schwann
D. Gregor Mendel.

Answer 1

Hint:- Cell is called the unit of life. The cell is composed of cytoplasm. A membrane called the cell
membrane or plasma membrane is responsible for surrounding the cell to separate it from the outer
environment. In the case of a prokaryotic cell it does not possess any membrane-bound organelles. Eukaryotic Cells involve nucleus, mitochondria, Golgi body, etc

Complete step-by-step solution:- The Greek philosopher Aristotle is known for his polymath. Aristotle left very important contributions in various subjects like maths, biology, botany, physics medicine etc.
B. English scientist Robert Hooke was born on 28 th July of 1635. Microorganisms are first observed
under the microscope by Robert Hooke.The cell was first discovered by Matthias Jakob Schleiden and Theodor Schwann, in the year 1839.They suggest that every organism is made up of one cell or more than one cell. These cells are known as the structural and functional unit of the organism.
D. Gregor Mendel was born on 20 th july in 1822. Mendal is called the father of modern genetics.

Note:- The cell is the smallest unit of an organism which is responsible for performing several functions.These are the formation of body structure, production of essential nutrients for survival, synthesis of the energy to maintain the biological functions etc. In plants, the cell is capable of photosynthesis which involves the synthesis of nutrients.
