How does life begins from a single cell called zygote?
How were those cells produced from a single cell called a zygote (a fertilized egg)?
I have recently learned about cells and I read that cells come from existing cell. So, where was the original cell made and how? Where are egg cells found? How was the first cell formed? How are human eggs fertilized? What is a zygote made of? How many chromosomes does a zygote have? What is a zygote? How was in vitro fertilization discovered? Why is it that only when a male and female gametes fuse, a zygote is formed? Why not when a sperm and sperm fuses? Is the parent cell in meiosis a gamete? What are pre-existing cells? What is found in animal cells but not plant cells? When was the cell first discovered? Who discovered the cell? What cell parts are only found in plant cells? How are chicken eggs fertilized? How could the first cell have appeared? How are embryonic and adult stem cells alike? Does a plant seed contain a single cell? What is an organism called when it is made of only one cell? When was In Vitro Fertilization discovered? What is cytosol in a cell? Why is the egg cell termed a secondary oocyte? How do individual cells know they are a part of a system and whether or not to stop or start producing new cells? What are lymphocytes? Where and how are they produced? What are cell membranes made out of? How is an organism affected by cell differentiation? How important is cytosol in a cell? Which parts of plant cells are not found in animal cells? How are haploid and diploid cells produced?
