Cells - The Unit of Life
Which one of the following structures is an organelle within an organelle?
Match the cell organelles given in column I with cellular processes in column II and select the correct option from the codes given below. Column I Column II A. Lysosomes (i) Protein synthesis B. Ribosomes (ii) Hydrolytic activity C. Smooth endoplasmic reticulum (iii) Steroid synthesis D. Centriole (iv) Formation of spindle
Lysosomes- contain hydrolytic enzymes, that digest foreign substances, obsolete cell organelles and biomolecules
Ribosome: the process of translation, of protein synthesis takes occurs at the ribosome
Smooth Endoplasmic reticulum: major function is lipid and steroid synthesis
Centriole: formation of aster and spindle fibres in animal cell during cell division
So, the correct answer is 'A−(ii),B−(i),C−(iii),D−(iv)'
