The correct Answer is:
To determine which statement is not correct among the provided options, we will analyze each statement step by step. ### Step 1: Analyze the First Statement The first statement claims that the material of the nucleus stained by an acidic dye was given the name "chromatin" by Flemming. - **Fact Check**: Chromatin was indeed discovered by Flemming in 1882, but it was stained using a basic dye, not an acidic dye. Therefore, this statement is incorrect. ### Step 2: Analyze the Second Statement The second statement mentions that Schleiden and Schwann together formulated the cell theory in 1838. - **Fact Check**: This statement is correct. Schleiden (a botanist) and Schwann (a zoologist) proposed the cell theory in 1838. ### Step 3: Analyze the Third Statement The third statement states that Rudolf Virchow modified the hypothesis of Schleiden and Schwann to give the cell theory its final shape. - **Fact Check**: This statement is also correct. Virchow contributed to the cell theory by stating "Omnis cellula e cellula," meaning that all cells arise from pre-existing cells. ### Step 4: Analyze the Fourth Statement The fourth statement claims that the living cell was the first one to be described. - **Fact Check**: The first living cell was described by Antonie van Leeuwenhoek in 1674. This statement is correct as it refers to the first description of a living cell. ### Conclusion After analyzing all statements, the first statement is the only one that is incorrect. It incorrectly states that chromatin was stained with an acidic dye when it was actually stained with a basic dye. ### Final Answer The statement that is not correct is the first one regarding chromatin being stained by an acidic dye. ---
