Question

12. Among the following statements which one is incorrect?
(a) Golgi apparatus is involved with formation of lysosomes.
(b) Nucleus, mitochondria and plastid have DNA, hence they are able to make their own structural proteins.
(c) Lysosomes are called the suicide bags as they eat up their own cells.
(d) Cytoplasm is called known as protoplasm.

Answer 1

Answer:

Nucleus, mitochondria and plastid have DNA, hence they are able to make their own structural proteins.

Answer 2

The incorrect statement among the following is that Cytoplasm is known as protoplasm ( option-D).

• Golgi apparatus is majorly involved in the packaging of protein in vesicles and target proteins to their target organelles such as lysosomes, therefore helping in the formation of lysosomes.
• Nulecus is the organelle in the cell that contains genetic material ( i.e. DNA or RNA) which forms all the structural and functional proteins of the cell.
• Mitochondria and plastid are semi-autonomous in nature as these organelles contain their own DNA, hence able to make their own structural proteins.
• Lysosomes are known as "the suicidal bag of a cell" because these organelles contain hydrolase enzymes that eat up their own unwanted, aged or degraded cells.
• The cytoplasm is the main arena of a cell where all cellular activities take place. But it is not the protoplasm of a cell as it is the part of protoplasm. Because a protoplasm comprises of nucleus, organelles, and cytoplasm of a cell.
