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 plants producing flowers. Thus, they are also commonly called as the flowering plants. They belong to the Kingdom Plantae, Subkingdom Embryophyta. The distinctive features of Angiosperms are as follows: The reproductive organs in flowers of these plants enable them to utilize a more species-specific breeding system They have stamens that bear pollen.
