Question

Match the columns and identify the correct option.

	I		II
(a)	Thylakoids	(i)	Disc shaped sacs in Golgi apparatus
(b)	Cristae	(ii)	Condensed structure of DNA
(c)	Cisternae	(iii)	Flat membranous sacs in stroma
(d)	Chromatin	(iv)	Infoldings in mitochondria

• A. a-iv, b-iii, c-i, d-ii
• B. a-iii, b-iv, c-i, d-ii
• C. a-iii, b-i, c-iv, d-ii
• D. a-iii, b-iv, c-ii, d-i

Answer 1

The correct option is B a-iii, b-iv, c-i, d-ii

a) Thylakoid (internal photosynthetic membranes) is a membrane-bound compartment present within the stroma (ground matrix) of the cellular organelle called chloroplast.

b) The inner mitochondrial membrane has folds called cristae which helps in increasing the surface area.

c) The folds of the Golgi apparatus are called cisternae which are called the functional units of this organelle.

d) Chromatin is a viscous, gelatinous substance made up of DNA, RNA, basic proteins called histones or acidic proteins called nonhistones.

So, the correct answer is 'a-iii, b-iv, c-i, d-ii'.
