They are called sex cells, or to be more scientific, gametes.
gametes
Neither. The union of a sperm and egg is called fertilization. Both sperm and egg cells are sex cells that are produced through meiosis.
gametes
because the sperm cells fail to find the egg cells or the sperm isn't good to unite with the egg
gametes, sperm, egg
Once a sperm enters the egg, fertilisation of the egg begins.
Sperm cells and egg cells named together are called gametes.
Conception
Neither. The union of a sperm and egg is called fertilization. Both sperm and egg cells are sex cells that are produced through meiosis.
Sperm and egg cells are the result of meiosis.
gametes
The cell formed after fertilization by sperm and egg is called a zygote. A zygote is a diploid cell, meaning a cell that has two sets of chromosomes (one from egg, one from sperm).
this is called prophase
because the sperm cells fail to find the egg cells or the sperm isn't good to unite with the egg
gametes, sperm, egg
Internal fertilisation.
Once a sperm enters the egg, fertilisation of the egg begins.
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
