<span>As the pollen tube penetrates the ovule, it releases two sperm cells. As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.</span>

Explanation:
According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell.
The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.
Answer:
The DNA is copied by B: The sense strand of DNA is used as a template to create both strands of the new double helix.
Explanation:
Ok, the DNA is "copied" in the tanscription process. The transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Also, the DNA safely stores genetic material.
During the process of transcription a single strand of RNA is synthesized using a double stranded DNA molecule as a template. The two strands of the DNA molecule are separated from one another, exposing the nitrogenous bases. Only one strand is actively used as a template in the transcription process, this is known as the sense strand, or template strand. The complementary DNA strand, the one that is not used, is called the nonsense or antisense strand.
