Question

Three of the following statement 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 tubules and helps in transport, synthesis and secretion.
• C. Leucoplasts are bound by two membranes, lack pigment but contain their own DNA and protein synthesizing machinery.
• D. Spherosomes are single membrane bound and are associated with synthesis and storage of lipids.

Answer 1

The correct option is A Lysosomes are double membraned vesicles budded off from Golgi apparatus and contain digestive enzymes.

Lysosomes are small vesicles containing hydrolyzing enzymes and surrounded by a single membrane of up to 100 nanometers in thickness. It is formed by the Golgi body. Whereas endoplasmic reticulum is a membranous network in the cytoplasm that involved in the formation and transportation of proteins, lipids, steroids etc., leucoplast is the colourless double-membrane bounded plastid which possesses their own DNA and protein synthesising machinery. Spherosomes are the small spherical organelle found in the cytoplasm of the plant cells. It is a single membrane-bounded structure which involved in the formation and storage of lipids in plant cells. Thus, the correct answer is option A.
