NEET 2016 Phase 1 · BiologyEndomembranePrevious Year Question

Water soluble pigments found in plant cell vacuoles are:

Answer: (D) Anthocyanins. Answer: (D) Anthocyanins Solution: Anthocyanins are water-soluble pigments that dissolve in the cell sap held within plant vacuoles, giving red, purple and blue colours to flowers and fruits.

  1. A.Xanthophylls
  2. B.Chlorophylls
  3. C.Carotenoids
  4. D.Anthocyanins✓

Correct Answer

(D) Anthocyanins

Solution & Explanation

Answer: (D) Anthocyanins Solution: Anthocyanins are water-soluble pigments that dissolve in the cell sap held within plant vacuoles, giving red, purple and blue colours to flowers and fruits. The other options — xanthophylls, chlorophylls and carotenoids — are fat-soluble (lipid-soluble) pigments located in plastids (chloroplasts/chromoplasts), not in the vacuole. This is an extension beyond the NCERT text: NCERT states the vacuole contains water, sap and other materials, while the listed plastid pigments are described as carotenoid/chlorophyll pigments of plastids. NCERT Reference: Ch 8, p.96, lines 33–34: "The vacuole is the membrane-bound space found in the cytoplasm. It contains water, sap, excretory product and other materials not useful for the cell."

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. The endomembrane system includes Golgi complex, endoplasmic reticulum and mitochondria. B. Rough endoplasmic reticulum bears ribosomes on its surface. C. Both mitochondria and plastids have circular DNA. D. A network of microtubules, microfilaments and intermediate filaments present in the cytoplasm is called cytoskeleton. E. Mitochondrion is a single membrane-bound structure.
