M.Schleiden a German botanist examined a large number of plants and observed

Options

A. all plants are compared by cells similar in structure and function
B. all plants contain dissimilar cells of different function
C. all plants are formed by both similar and dissimilar cells
D. all the plants are formed by different kinds of cells which form the tissue of the plant

Answer

**Step-by-Step Solution:**

1. **Understanding M. Schleiden's Contribution**: M. Schleiden was a German botanist who studied a variety of plants. His observations were crucial in the development of the cell theory.

2. **Observation of Plant Cells**: Schleiden observed that all plants are composed of cells. He noted that these cells are similar in structure and function, indicating a commonality among plant cells.

3. **Diversity in Plant Cells**: While he recognized that plant cells share similarities, he also noted that there are dissimilar cells within plants that perform different functions. This highlights the complexity of plant tissues.

4. **Formation of Tissues**: Schleiden concluded that plants are formed by tissues, which are groups of cells. These tissues can be made up of both similar and dissimilar cells, contributing to the overall function of the plant.

5. **Collaboration with Other Scientists**: Schleiden's work was part of a larger framework of the cell theory, which he co-developed with Theodor Schwann and Rudolf Virchow. They collectively established that all living organisms are composed of cells, whether plant or animal.

6. **Final Conclusion**: The essence of Schleiden's findings is that all plants are made up of tissues formed by various types of cells, which can be similar or different in function.
