Maximum DNA synthesis during the midproliferative phase of the cycle (i.e. cycle days 8â10) correlates with the maximum number of mitoses in both the stromal and epithelial endometrial cellular elements, as well as with the midproliferative peak of plasma estradiol and nuclear estradiol receptors.
Some defining characteristics of angiosperms include flowers, carpels, and the presence of endosperm, a nutritive substance found in seeds, produced via a second fertilization event. However, some current studies suggest that endosperm is not unique to angiosperms.
Gymnosperms do not have flower whereas angiosperms have flower The seed of the gymnosperms is unprotected (naked seed) compared to angiosperm's seed is protected in ovary. Gy â¦ mnosperms consists of tracheid (except Gnetum sp.ngiosperms and gymnosperms are both seed-bearing plants. However, angiosperms produce flowers, while gymnosperms just have plain, uncovered seeds. Pine trees, for example, ar â¦ e gymnosperms because they have cones with seeds that simply fall out when the cones are opened. I hope that helped you!
