Match List I with List II List I List II A Nucleolus I Optimally active at the acidic pH B Smooth Endoplasmic Reticulum II Important for osmoregulation in Amoeba C Lysosomes III Non-membrane bound structure continuous with nucleoplasm D Contractile Vacuole IV Synthesis of steroidal hormones in animal cells Choose the correct answer from the options given below:

Step-by-step solution

Nucleolus is a non-membrane bound structure present in the nucleoplasm and is continuous with the rest of the nucleoplasm. It is a site for active ribosomal RNA synthesis. Thus, A matches with III. Smooth Endoplasmic Reticulum (SER) is the major site for the synthesis of lipids. In animal cells, lipid-like steroidal hormones are synthesized in the SER. Thus, B matches with IV. Lysosomes are membrane-bound vesicular structures containing hydrolytic enzymes (hydrolases - lipases, proteases, carbohydrases) which are o
