German botanist, Matthias Jacob Schleiden in 1838, observed different parts of the plants under the microscope and found that all of them are made up of cells. German zoologist, Theodor Schwann in 1839, observed parts of the animal body and noticed that cells had an outer layer which is also called as plasma membrane. Schleiden and Schwann together gave cell theory. This theory slates that bodies of all living organisms are made up of cells and their products. Rudolf Virchow studied that all cells arise from the pre-existing cells. In other words, the existing cells divide to form new cells. He stated this in Latin as “omnis cellula-e-cellula” and on this basis proposed the modern cell theory.

  • c)
    A is true but R is false.
  • d)
    A is false but R is true.

Understanding Cell Theory and Its Historical Context
The assertion and reason provided in the question relate to the formulation of cell theory and its historical background.
Assertion (A): Cell theory states that the unit of life is the cell.
- Cell theory is a fundamental principle in biology that outlines that all living organisms are composed of cells.
- It emphasizes that cells are the basic unit of structure and function in all living things.
Reason (R): Robert Hooke was the first to coin the term "cell."
- Robert Hooke, in 1665, used the term "cell" when he observed cork under a microscope.
- He described the microscopic compartments he saw as "cells," due to their resemblance to the cells inhabited by monks.
Analysis of the Options
- Option A states that both A and R are true, but R is not the correct explanation of A. This is accurate because while both statements are true, the reason does not directly explain the assertion.
- Option B suggests that both A and R are true and that R is the correct explanation of A. This is incorrect as the reason does not provide an explanation for the assertion about cell theory.
- Option C indicates that A is true, but R is false. This is incorrect since R is indeed true.
- Option D states that A is false but R is true, which is also incorrect.
Conclusion
Therefore, the correct answer is Option B: Both A and R are true, but R is not the correct explanation of A. This distinction highlights the importance of understanding the contributions of various scientists to the development of cell theory while recognizing that the historical context does not serve as a direct explanation for the assertion made.
