Direction: Q. 6 to 10

Read the following and answer the questions from [6] to [10].

Every cell has a membrane around it to keep its own contents separate from the external environment. Large and complex cells, including cells from multicellular organisms, need a lot of chemical activities to support their complicated structure and function.

To keep these activities of different kinds separate from each other, these cells use membrane bound little structures (or organelles) within themselves. This is one of the features of the eukaryotic cells that distinguish them from prokaryotic cells.

In prokaryotes, beside the absence of a defined nuclear region, the membrane bound organelles are also absent.

On the other hand, the eukaryotes cells have nuclear membrane as well as membrane-enclosed organelles.

Ribosomes are the centre for

A) respiration                                 

B) protein synthesis

C) photosynthesis

D) fat synthesis
