Question

What is Kranz anatomy ?
​

Answer 1

Kranz anatomy. the special structure of leaves in C4 PLANTS (e.g. maize) where the tissue equivalent to the spongy mesophyll cells is clustered in a ring around the leaf veins, outside the bundle-sheath cells. (The term 'Kranz' means wreath or ring in German).

Answer 2

NCERT based Answer for Class 11 Biology Students

Kranz anatomy:

 Large cells around vascular bundles of C4 plants are called bundle sheath cells and such anatomy is called Kranz anatomy.

Note: Kranz means ‘wreath’ (flowers arranged in a circle).

 Thus C4 plants have two types of photosynthetic cells: mesophyll cells and bundle sheath cells.

Note: Presence of two types of cells allows separation of light reactions and carbon fixation.

 C4 plants contain dimorphic chloroplasts.

 Chloroplasts in mesophyll cells are granal i.e., thylakoids are stacked to form grana.

 Chloroplasts in bundle sheath cells are agranal i.e., thylakoids are present as stromal lamellae.

 As a result, release of O2 takes place in mesophyll while CO2 fixation catalysed by RuBisCO occurs in bundle sheath cells.
