Step-by-step solution
According to NCERT, Theodore Schwann (1839), a British Zoologist, studied different types of animal cells and reported that cells had a thin outer layer which is today known as the plasma membrane. He also concluded, based on his studies on plant tissues, that the presence of a cell wall is a unique character of plant cells. Thus, the Assertion (A) is true. The Reason (R) describes the work of Matthias Schleiden (1838), a German Botanist, who examined a large number of plants and observed that all plants are compos
