Question

Find out the false statement.

• A. Nucleus, plastids and mitochondria contain DNA and hence, are able to make their own structural proteins.
• B. Mitochondria are said to be the 'power house' of the cell.
• C. Lysosomes are chlorophyll containing bags surrounded by a single unit membrane.
• D. Ribosomes are also called as Palade particles and are the 'protein factories' of the cell.

Answer 1

Answer: (C)

Lysosomes are chlorophyll containing bags surrounded by a single unit membrane.

Nucleus, plastids and mitochondria contain DNA. Transcription of DNA present in all these organelles can be carried out to form mRNA and such mRNA is translated to form required protein. Hence, they are able to make their own structural proteins. Mitochondria is called as powerhouse of cell as it produces and stores energy in the form of ATP. Ribosomes are also called as Palade particles as they are first discovered and described by George Palade. Ribosomes are involved in the process of protein synthesis.
Lysosomes are membrane bound cellular organelles. They possess many hydrolytic enzymes for the digestion of cellular waste, debris as engulfed, killed viruses or bacteria. Lysosomes are surrounded by a single membrane. Lysosomal membrane allows the digestive enzymes to work at lower pH. It also protects the cytosol from digestive enzymes. Chlorophyll pigment is produced and stored in chloroplast.
So, option C is the correct answer.
