Someone told me that eggs and seeds are not alive so in this case living is produced from non-living. But I studied in biology that concept of Abiogenesis is obsolete and only biogenesis (living beings can product living beings) is accepted now. So if Eggs, Seeds and Ova of women are considered alive then how it should be explained.
You ask a difficult question which doesn’t have a simple answer.
Certainly everyone would agree that an egg is alive, but starting from the other end is harder
Is a virus alive? Most biologists would say that all life is built on cells. Viruses are not cells nor are they composed of cells… they need to infect a living being (a cell) to reproduce… not alive
What about a bacterial spore (endospore)? A spore is a bacterial cell with no metabolism, but an endospore can grow and divide if you put it in the right environment …alive?
Finally seeds! Are seeds alive?
At one time, the theory was that since seeds consumed oxygen (had active metabolism) then they must be alive. But decay also would consume oxygen. At other times, theories were popular that living things had an energy or spirit that separated from non-living. But no evidence was ever found that support those ideas.
So I would put it this way, biological life can make forms (viruses, endospores?, seeds??) which are not living, but which are capable of life. I would argue that your definition of biogenesis as living beings can produce living beings is correct, since it does leave open the possibility that a “non-living” intermediate can exist.
I don’t see that this as any different from taking an egg (alive) from a women and putting it into a liquid nitrogen freezer. The frozen egg is not alive, but if you warm it up treat it properly it can be fertilized & grow into a human being.
That's right. Eggs and sperm and seeds are all alive. Very much so.
A chicken egg consists of a single, huge, living cell, plus some nutrients in the yolk, some membranes, and a shell (which is not alive). The egg may or may not get fertilized, but it is alive either way.
Sperm form from living cells by dividing. They are alive for a short period of time, usually a few days.
A woman's ova also form from dividing cells that are alive. All ova in all animals and plants are alive.
A seed forms when a plant "egg," or ovum, is fertilized by the sperm from pollen. Once the ovum (plant egg) and sperm DNA fuse to form a fertilized egg, the rest of the seed forms around it, supplying nutrients and a protective husk that keeps it from drying out. A seed is a lot like a fertilized bird egg except that the seed can stay dormant for a long time (thousands of years!), while a bird egg needs to be kept warm and develop into a bird right away. Reptile eggs, also alive, are very similar to bird eggs. In fact, birds, reptiles, and mammals all have similar "amniotic" eggs.
Viruses are not considered alive because they are not cells and the formal definition of life is that all life is made from cells. This is a technicality. Viruses carry information in DNA or RNA and they can evolve, just like other living things. Whether they are formally "life" or not, they are certainly related to living things. And everything else is alive. Ova, sperm, and seeds are all made of cells and are alive.
