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.
In common terms, angiosperms are all flowering plants. They are distinguished from gymnosperms, by their ability to flower and produce seeds enclosed in fruits. There are a few other characteristics that are discussed in the following paragraphs.s you can see, angiosperms are dicots (flower with stamens and pistils in separate flows on same or different plant) and monocots (stamens and pistils on the same flower). The root and shoot system is the prime feature of angiosperms. They are the major food sources for animals as well as humans.
