The correct Answer is:
To determine how many statements are not incorrect, we will analyze each statement one by one. ### Step 1: Analyze the First Statement **Statement 1:** "Schleiden gave the cell hypothesis." - **Analysis:** Schleiden, along with Schwann, contributed to the formulation of the cell theory, not a hypothesis. The cell theory states that all living organisms are made up of cells and that new cells arise from existing cells. Therefore, this statement is incorrect. ### Step 2: Analyze the Second Statement **Statement 2:** "Golgi bodies are extensive and continuous with the outer membrane of the nucleus." - **Analysis:** While Golgi bodies are extensive structures, they are not continuous with the outer membrane of the nucleus. Instead, the endoplasmic reticulum is continuous with the outer membrane of the nucleus. Thus, this statement is also incorrect. ### Step 3: Analyze the Third Statement **Statement 3:** "Endomembranous system contains vacuoles." - **Analysis:** This statement is correct. The endomembrane system includes various organelles such as the endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles. Therefore, this statement is not incorrect. ### Step 4: Analyze the Fourth Statement **Statement 4:** "Peroxisome coordinates with Golgi bodies." - **Analysis:** Peroxisomes are not part of the endomembrane system and do not coordinate with Golgi bodies. They are involved in various metabolic processes but do not have a direct functional relationship with Golgi bodies. Hence, this statement is incorrect. ### Conclusion After analyzing all four statements, we find that only the third statement is correct. Therefore, the number of statements that are not incorrect is **1**. ### Final Answer **1 statement is not incorrect.** ---
