Question

Sporopollenin is secreted by
A. Cytoplasm of the pollen
B. Cytoplasm of the pollen mother cell
C. Cytoplasm of the tapetum
D. Cytoplasm of the endothecium

Answer 1

answer c is the correct option

Answer 2

Option “C” is correct i.e. Cytoplasm of Tapetum

• Numerous Enzymes of the Sporopollenin Pathway Restrict to the endoplasmic reticulum. Exine elements are produced in the tapetum cell layer of the anthers and then are concealed into the locules.

• This suggests a high rate of synthesis of sporopollenin monomers and therefore well-organized catalysis of products by the enzymes elaborate in the pathway
