Site for protein manufacture is (a) Cell wall (b) Cytoplasm (c) Ribosome (d) Inclusion bodies

To determine the site of protein manufacture, we need to first understand the roles of each of the four options provided: - (a) Cell wall: This is a rigid outer layer found in plant and bacterial cells, which provides structural support and protection. - (b) Cytoplasm: This is the jelly-like substance within the cell, which contains various cellular components. Important cellular processes, including protein synthesis, take place within the cytoplasm. - (c) Ribosome: These are small cellular structures made of proteins and RNA that are the site of protein synthesis. They read the genetic information in the form of messenger RNA (mRNA) and translate it into amino acids to build proteins. - (d) Inclusion bodies: These are cellular storage units that store nutrients or waste products within the bacterial cell.

After understanding the roles of these cellular structures and components, we can conclude that the ribosome (c) is the site where proteins are synthesized or manufactured. Ribosomes read the mRNA molecule containing the genetic code to build proteins, conducting the translation process to convert the genetic information into proteins that are crucial for the cell's function. Therefore, the correct answer is (c) Ribosome.
