Match List-I with List-II.

List-I

A. Centromere

B. Cilium

C. Cristae

D. Cell membrane

List-II

I. Mitochondrion

II. Cell division

III. Cell movement

IV. Phospholipid Bilayer

Choose the correct answer from the options given below:

Solution:

Let's match the items in List-I with those in List-II:

A. Centromere: The centromere is a constricted region of a chromosome that serves as the attachment point for spindle fibers during cell division. Therefore, A matches with II (Cell division).

B. Cilium: Cilia are hair-like projections from the cell surface involved in cell movement or the movement of substances across the cell surface. Therefore, B matches with III (Cell movement).

C. Cristae: Cristae are the folds of the inner membrane of a mitochondrion, which increase the surface area for cellular respiration. Therefore, C matches with I (Mitochondrion).

D. Cell membrane: The cell membrane (or plasma membrane) is primarily composed of a phospholipid bilayer, which forms the basic structure of the membrane. Therefore, D matches with IV (Phospholipid Bilayer).

Combining these matches:

A - II

B - III

C - I

D - IV

This corresponds to option (4).
