The correct Answer is:
To analyze the statements provided in the question, we will evaluate each one step by step. ### Step-by-Step Solution: 1. **Statement (a): Small, circular non-histone DNA also present in mitochondria and chloroplast.** - **Evaluation:** This statement is correct. Mitochondria and chloroplasts contain their own DNA, which is circular and not associated with histones, similar to prokaryotic DNA. This is a result of their evolutionary origin from free-living bacteria. 2. **Statement (b): The extension of plasma membranes mesosomes into the cell can be present in the form of tubules, lamellae, and vesicles.** - **Evaluation:** This statement is also correct. Mesosomes are infoldings of the plasma membrane found in prokaryotic cells, and they can take various forms, including tubules, lamellae, and vesicles. They play roles in cellular processes such as respiration and DNA replication. 3. **Statement (c): The quasi-fluid nature of lipid enables flip-flop movement of proteins at a specific place.** - **Evaluation:** This statement is incorrect. While the lipid bilayer of the cell membrane is indeed quasi-fluid, proteins primarily exhibit lateral movement within the bilayer rather than flip-flop movement. Flip-flop movement refers to the movement of lipids between the two layers of the bilayer, which is not common for proteins. 4. **Statement (d): Components of the endomembrane system associated with secretion, packaging of material, and capable of digestion of several macro-organic compounds.** - **Evaluation:** This statement is correct. The endomembrane system includes organelles such as the endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles, which are involved in the secretion, packaging, and digestion of various substances. 5. **Statement (e): Palade particles forming a peptide bond between amino acids is a membrane-bounded organelle.** - **Evaluation:** This statement is incorrect. Palade particles, now known as ribosomes, are not membrane-bound organelles. They are involved in protein synthesis by forming peptide bonds between amino acids but are found in both prokaryotic and eukaryotic cells, where they lack membranes. ### Summary of Correct and Incorrect Statements: - **Correct Statements:** (a), (b), (d) - **Incorrect Statements:** (c), (e) ### Final Answer: The correct statements are (a), (b), and (d). The incorrect statements are (c) and (e). ---
