an zygote
assuming you mean the earliest developmental stages of life. Your dna is the result of the genetic material from your mother's egg and your father's sperm combining and copying itself as you gain more and more cells.
the process is called fertilisation and these gametes fuse and form a zygote
plants do not produce sperm, they produce pollen
No, sperm cannot penetrate clothing and result in pregnancy. Direct contact with the vagina is needed for sperm to fertilize an egg.
Nonvascular plants, such as mosses and liverworts, do not produce sperm. They rely on water for the movement of their sperm cells to reach the egg for fertilization.
No, sperm in the colon will not result in pregnancy. However, the fact that the sperm is there shows close proximity to the areas that do result in pregnancy.

No.
Antheridia are structures in seedless plants that produce sperm. They are typically found on the gametophyte generation of plants like ferns and mosses. Within the antheridia, sperm cells are produced through a process of spermatogenesis.
Double fertilization occurs in flowering plants, where one sperm fertilizes the egg to form a zygote, while the other sperm fertilizes the polar nuclei to form the endosperm. The endosperm provides nutrients to the developing embryo.
The mobile sexual reproductive parts of seedless plants are sperm cells. These sperm cells are typically flagellated, allowing them to swim through water to reach the egg for fertilization. Seedless plants rely on water for the transfer of sperm to the egg, unlike seed plants which have pollen to transport sperm to the egg.
