Q.Match the following:

Cristae = convoluted inner mitochondrial membrane (iii); Chromatin = thread-like DNA (iv); Vesicles = oval membrane-bound vacuolar structures (i); Mitochondria = semi-autonomous organelle (ii) — giving (1)-(iii), (2)-(iv), (3)-(i), (4)-(ii).

Match each term to its correct description:

1. Cristae — the finger-like infoldings of the inner mitochondrial membrane, which increase surface area for the electron transport chain. This matches description (iii), 'convoluted inner membrane of mitochondria'.
2. Chromatin — the loosely coiled, thread-like form of DNA (with associated histone proteins) seen in the interphase nucleus. This matches description (iv), 'thread like structures of DNA'.
3. Vesicles — small, oval, membrane-bound sacs used for transport/storage within the cell (e.g. derived from Golgi or endoplasmic reticulum). This matches description (i), 'oval membrane bound vacuolar structure'. …
