In this study, the whole transverse and longitudinal sections of maize mature dent, flint, and pop kernels were observed to reveal and compare the morphological characteristics of cell, starch, and protein in different regions of endosperm. Wheat seeds provide a staple food and an important protein source for the world’s population. II. Thus, the correct answer is option B. White-belly and white-core also varied markedly in morphological features of the cracked compound starch granules. Our findings should help to advance our understanding of the multi-faceted nature of grain chalkiness from the perspective of starch and protein accumulation, and should be of value for future work on rice grain chalkiness. Meaning of Endosperm: The endosperm makes the main source of food for the embryo. This study was conducted to estimate the effect of maize endosperm type, e.g., waxy, conventional, fodder, sweet, and high oil, and maturity stage on chemical composition and in vitro fermentation characteristics of morphological fractions. Correct! MORPHOLOGICAL AND EMBRYOLOGICAL STUDIES ON THE LEMNACEAE. View solution. morphological nature of the endosperm of angiosperms. By drawing ... 50. DEVELOPMENT OF ENDOSPERM The primary endosperm nucleus divides repeatedly. ... PCD in starchy cereal endosperm and during self-incompatibility. Whereas TIP3-GFP-labelled PSVs in the aleurone did not change significantly, those in the other tissues reduced in size during development, particularly in the central starchy endosperm. Endosperm, the tissue that surrounds and nourishes the embryo in the angiosperm seed. The vitreous and floury endosperms have regional distributions in maize kernels, and influence their qualities and applications.
