What is meant by kranz anatomy

Answer 1

Answer:

hope it help

Explanation:

Kranz Anatomy Definition. Kranz anatomy is a unique structure observed in C4 plants. In these plants, the mesophyll cells cluster around the bundle-sheath cell in a wreath formation (Kranz means 'wreath or ring). Also, the number of chloroplasts observed in bundle sheath cells is more than that in the mesophyll cell.

Answer 2

Answer:

The word Kranz means “wreath” or “ring”. Kranz anatomy is a specialized structure in C4 Plants where the mesophyll cells are clustered around the bundle-sheath cells in a ring-like fashion. The number of chloroplasts in the bundle-sheath cells is more than that in the mesophyll cells. This is found in C4 grasses such as maize and a few dicots. The Kranz anatomy is developed in three different steps:

Initiation of procambium

Bundle sheath and mesophyll cell specification

Chloroplast development and integration of the C4 cycle

Kranz Anatomy in C4 Plants

The light-dependent reactions and the Calvin cycle are separated in the C4 plants. The Calvin cycle occurs in the bundle-sheath cells and the light-dependent reactions occur in the mesophyll cells.

The atmospheric oxygen is fixed first to form 4-carbon compound oxaloacetate in the mesophyll cells, catalyzed by PEP carboxylase.

Oxaloacetate is converted to malate which is transported to the bundle-sheath cells.
