Frage 2
Frage
Complete each of the following sentences
The first diploid cell formed by fusion of egg and sperm is a [blank_start]zygote[blank_end].
A [blank_start]Blastocyst[blank_end] is the early stage in development before implantation, it consists of an outer trophoblast and an inner cell mass.
An [blank_start]Embryo[blank_end] is an egg that has been fertilised by a sperm that has undergone one or more divisions
[blank_start]Cleavage[blank_end] results in a solid cluster of cells called a [blank_start]Morula[blank_end].
The Accumulation of secretions within the trophoblast lead to the formation of a cavity called the [blank_start]Blastocele[blank_end].
