No, they use external fertilization by "shooting" out their spores when they fall to the ground. The spores will overtime be buried in the ground and then a new pine tree will grow with enough resources.
The joining is called fertilization. The sperm is said to "fertilize" the egg when it enters the egg, producing a zygote, a one cell embryo. It is now a sperm's DNA paired up with the egg's DNA. Then the zygote starts dividing into more cells and is called a blastocyst (a multi-celled embryo) and when the cells start to differentiate it is called a fetus.
They form from the merger of two haploid (half-gened cells: a sperm and an egg). Actually in mammals the egg swallows the sperm, and the nuclear material fuses together.
the ovary after fertilization swells rapidly to form the fruit
Animal zygotes divide to form more cells. The zygote divides itself many times by mitosis until an embryo is formed.

can seeds form without pollination and fertilization
If the animal is a bird, then it has wings.
This form of birth control does not interfer with fertilization but does inhibit inplantation
The grammatically correct statement is "She does not have her book." In English, the verb "have" is used as an auxiliary verb in negative sentences, so the correct form is "have" instead of "has."
Oxygen is transported to body cells in the form of oxyhemoglobin.
