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.
Angiosperms are flowering plants that produce seeds enclosed within an ovary structure, or fruit. The process of double fertilization is common to all angiosperms as well as a few of the gymnosperms, or plants that produce seeds not enclosed in an ovary.Other People Are Reading.he process of double fertilization is common to all angiosperms as well as a few of the gymnosperms, or plants that produce seeds not enclosed in an ovary.
