The cells of the embryo undergo organogenesis during different organs such as heart, brain, lungs et cetera are formed. Zygote meaning as stated above is a reference to a cell right after fertilization of the gametes. STUDY. In general, in organisms that reproduce sexually, embryonic development refers to the portion of the life cycle that begins just after fertilization and continues through the formation of body structures, such as tissues and organs. Refers to a point in the embryo's development where it takes on a more human form, and some bodily functions begin to work. Terms in this set (3) zygote .

Psycho blastocyst embryo fetus, zydeco embryo, blastocyst fetus, psycho embryo fetus, blastocysts or blastocysts, Zygote fetus, embryo. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to form an individual. In multicellular organisms, the zygote is the . What is an embryo? The zygote contains a full set of chromosomes, with 23 from the egg and 23 from the sperm. After the blastocyst has implanted itself within the womb, new cellular . A fertilized egg, or zygote, takes about five days to reach the uterus from the uterine tube. The next stage in fetal development has the name of the blastocyst. Biology. This is a crucial moment, since some embryos won't be able to implant. The first week of human development begins with fertilization of the egg by sperm forming the first cell, the zygote. Process of fertilization: (a) Fertilization is the process in which sperm and egg fuse to form a zygote. The zygote phase lasts only about four days, after which the single cell splits rapidly to become a blastocyst and then an embryo.
