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

Solution

Lysosomes are roughly spherical bodies bounded by a single membrane. They are manufactured by the Golgi apparatus. Lysosomes are small membrane bound vesicles in the cytoplasm of cells which contain toxic enzymes. When a cell dies, these membranes rupture and the enzymes are released. They break down the cells structure, and the debris is removed.
