Three of the following statements regarding cell organelles are correct, while one is wrong. Which one is wrong? |
|||
|
a) |
Lysosomes are double membraned vesicles budded off from Golgi apparatus and contain digestive enzymes |
b) |
Endoplasmic reticulum consists of a network of membranous tubule and helps in transport, synthesis and secretion |
|
c) |
Leucoplasts are bound by two membranes, lack pigment but contain their own DNA and protein synthesising machinery |
d) |
Sphaerosomes are single membrane bound and are associated with synthesis and storage of lipids |

(a) Double membranes are absent in lysosomes. They are enclosed by lipoproteinaceous unit membrane. Lysosome is called ‘suicidal bag’ of the cell due to presence of hydrolytic enzymes. |
