The correct Answer is:
To solve the question, we need to evaluate each statement provided and identify which ones are incorrect. Let's analyze each option step by step. ### Step 1: Evaluate Statement A **Statement A:** Small, circular DNA is also present in mitochondria and chloroplast. - **Analysis:** This statement is correct. Mitochondria and chloroplasts contain small, circular DNA, which is a characteristic of semi-autonomous organelles. They have their own DNA and ribosomes, allowing them to synthesize some of their own proteins. ### Step 2: Evaluate Statement B **Statement B:** The extension of plasma membranes mesosomes into the cell can be present in the form of tubules, lamellae, and vesicles. - **Analysis:** This statement is also correct. Mesosomes are indeed infoldings of the plasma membrane in prokaryotic cells, and they can take various forms, including tubules, lamellae, and vesicles. ### Step 3: Evaluate Statement C **Statement C:** The quasi-fluid nature of lipid enables flip-flop movement of proteins at a specific place. - **Analysis:** This statement is incorrect. The quasi-fluid nature of the lipid bilayer allows for the lateral movement of proteins and lipids, but not specifically at a "specific place." The term "flip-flop" typically refers to the movement of lipids between the two layers of the bilayer, not proteins, and it does not occur at a specific location. ### Step 4: Evaluate Statement D **Statement D:** Components of the endomembrane system are associated with secretion, packaging of material, and capable of digestion of several macromolecular compounds. - **Analysis:** This statement is correct. The endomembrane system includes structures like the Golgi apparatus, endoplasmic reticulum, lysosomes, and vacuoles, which are involved in secretion, packaging, and digestion of macromolecules. ### Step 5: Evaluate Statement E **Statement E:** Palade particles forming a peptide bond between amino acids is a membrane-bounded organelle. - **Analysis:** This statement is incorrect. Palade particles refer to ribosomes, which are non-membrane-bound organelles. They are involved in protein synthesis by forming peptide bonds between amino acids. ### Conclusion After evaluating all statements: - **Correct Statements:** A, B, D - **Incorrect Statements:** C, E Thus, the wrong statements are **C and E**. ### Final Answer The wrong statements are **C and E**. ---
