Both Schwann and M.J.Schleiden<\/strong><\/p>\n<p>Schwann and Schleiden were two German scientists who independently formulated the cell theory in the 1830s. Schwann proposed that all animal tissues are made up of cells, while Schleiden proposed that all plant tissues are made up of cells. They also proposed that cells are the basic units of life and that all cells come from preexisting cells.<\/p>\n<p>Dutrochet was a French scientist who also made important contributions to the cell theory. He was the first to propose that all living things are made up of cells, and he also showed that cells are able to divide and reproduce.<\/p>\n<p>The cell theory is one of the most important concepts in biology. It provides a basic framework for understanding the structure and function of living things. It also helps us to understand how diseases can spread and how to treat them.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li><strong>A.

He also showed that cells are able to divide and reproduce.<\/p>\n<ul>\n<li><strong>B. M.J.Schleiden<\/strong><\/li>\n<\/ul>\n<p>The German botanist Matthias Jakob Schleiden (1804-1881) was another founder of cell theory. In 1838, he published a book called &#8220;The Plant Cell,&#8221; in which he proposed that all plant tissues are made up of cells.
