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.
Once fertilization occurs a seed will form around the new embryo. Inside the seed will be the embryo and endosperm protected by the seed coat. The seed may be a nut or fruit covered by a fleshy covering. These may be sweet (apple), sometimes not (tomato). The seed can then be dispersed/scattered from the parent plant and germinate to create a new (sporophyte) plant. 80.
