Question

Kranz anatomy is one of the characteristics of the leaves of
a. Mustard
b. Potato
c. Wheat
d. Sugarcane

Answer 1

Hint: The term Kranz means “ring”. The Kranz anatomy is found in the C4 plants. It is basically a structure present in the chloroplast, in which mesophyll cells are clustered, in a ring like form, around the bundle sheath cells.

Complete answer:
The bundle sheath cells are large cells in some plants and are present around vascular bundles. Leaves that have such anatomy are called Kranz anatomy. It represents the arrangement of cells. The Kranz anatomy is produced in three steps. The first step is the initiation of procambium, second step is specification of bundle sheath cells and mesophyll cells, and the third step is development of chloroplast.

The bundle sheath cells produce several layers around vascular bundles, forming a large number of chloroplasts and no intercellular space is left. The Kranz anatomy present is $C_4$ grasses, for example maize, sugarcane, etc.

Hence, the correct answer is option (D).

Additional information:
Sugarcane is a perennial grass of the genus Saccharum and is used in production of sugar. The plant is tall and is a good source of sucrose which is present on the internodes of stems. The leaf of sugarcane has two parts- sheath and bundle. The leaves are connected to nodes alternately. The epidermis protects tissue present under it. Mesophyll is the middle layer that contains the cell performing photosynthesis. The fibro-vascular bundles contain vascular tissues.

Note: Sugarcane is grown in temperate to tropical regions of Asia and New Guinea. By quantity, it is the largest grown crop and is cultivated in more than 90 countries over 64 million acres of land. The sugar available commercially is made mostly by sugarcanes (about 70%).
