“For example, low temperatures near flowering affect ovule development and pollen tube growth.”

“However, at anthesis they appear one above the other, because in one ovule the funicle greatly elongates.”

“Tieghem placed Aquifoliaceae near Solanaceae because of the unitegmic ovule and the isomerous stamens alternating with the petals.”

“The two membranes, the liquor amnii, and the inclosed ovum, are called the ovulum!”

“We rather think of the latter as a new form of life to whose nature both the ovum and the spermatozoon have made significant contributions.”

“When a human sperm fertilizes a human ovum, a single cell is created with the potential to grow into a human person.”

“As in most other animals, the sperm mitochondria penetrate the cell membrane of the ovum at fertilization.”

“Still another possibility is for her to control either her ovulation or the maturation of her eggs after she is inseminated by certain males.”

“The BabyStart kit contains a his-and-hers package of a sperm concentration test and six ovulation testers.”

“Treatment with fertility drugs did not improve ovulation rates in these studies.”

“The Ovula were placed by Linnus in his genus bulla, from which they are very remote.”

“Like other seed plants, angiosperms are heterosporangiate, producing pollen and ovules in different organs.”

“As the ovary elongates only above the placenta, the ovules appear basal at anthesis.”

“The entire placenta with attached ovules was removed via a longitudinal incision in the ovary wall.”

“The ovary consists of a cortical zone composed of a specialized stroma, which contains follicles with ova.”

“De Graaf, working without the aid of a microscope, made the error of thinking that the fluid-filled follicles were the ova themselves.”

“He has informed us that there is a process, and not a rare one, of wastage or discharge of flawed fertilized ova.”
