NEET 2016 Phase 1 · BiologyEndomembranePrevious Year Question
Which one of the following cell organelles is enclosed by a single membrane?
Answer: (C) Lysosomes. Answer: (C) Lysosomes Solution: Lysosomes are membrane-bound vesicular structures bounded by a single membrane, formed by the packaging process in the golgi apparatus.
- A.Mitochondria
- B.Chloroplasts
- C.Lysosomes✓
- D.Nuclei
Correct Answer
(C) Lysosomes
Solution & Explanation
Answer: (C) Lysosomes Solution: Lysosomes are membrane-bound vesicular structures bounded by a single membrane, formed by the packaging process in the golgi apparatus. In contrast, mitochondria and chloroplasts are each double membrane-bound organelles, and the nucleus is enclosed by a nuclear envelope consisting of two parallel membranes. Hence lysosomes are the only single-membrane organelle among the options. NCERT Reference: Ch 8, p.96, lines 25-26: "These are membrane bound vesicular structures formed by the"

BiolGiven below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The primary function of the Golgi apparatus is to package the materials made by the endoplasmic reticulum and deliver it to intracellular targets and outside the cell. Reason (R): Vesicles containing materials made by the endoplasmic reticulum fuse with the cis face of the Golgi apparatus, and they are modified and released from the trans face of the Golgi apparatus. In the light of the above statements, choose the correct answer from the options given below:BiolChoose the correct statements regarding cell organelles and their inclusions. A.
