I read the generalization that life originates from a cell, and from my understanding animals, they originate from a single cell, produced as a result of sexual reproduction. And then life begins to develop from there on. But when it comes to botany, I stumble upon this doubt because of plant seed varieties. During any stage of seed production, can the seed be designated as having come from a single cell. Can i use the following generalization and correct me wherever i am wrong.
every life is made of cells, and every life comes from a single cell
