In cereals, one or few outermost layers of the endosperm become highly specialised morphologically and physiologically and constitute the aleurone tissue. Which of the following statements regarding aleurone tissue (or aleurone cells) is incorrect ?

Options

A. Aleurone cells are characterised by the presence of thin walls and vacuolated cytoplasm with single small nucleus.
B. Aleurone grains, rich in proteins are present in these cells.
C. Aleurone grains present in aleurone cells ae closely associated with sphaerosomes.
D. During seed germination, the reserve food of endosperm is digested by the activity of certain hydrolytic enzymes secreted by aleurone cells.

Answer

A

Explanation

The aleurone cells are characterised by the presence of thick walls and non-vacuolated cytoplasm interconnected by plasmodesmata. The most prominent organelles of these cells are aleurone grains, followed by sphaerosomes.
