Reproductive System Flashcards
production of gametes (sperm cell and egg cell)
continuous prolific in males
only active in females up to 50 years old
gametogenesis
fusion of two haploid cells from different individuals, forming a zygote
sexual reproduction
generation of new individuals without the need of fertilization (fusion of sperm and egg)
binary fission as an example
asexual reproduction
assignment of divided cells into specialized functions
differentiation
group of cells from a divided zygote that shows first cell differentiation into three germ layers
gastrula
becomes future epidermis, nervous system and sensory organs
ectoderm
becomes future skeletal, muscular, circulatory, excretory and reproductive system
mesodorm
becomes future liver and thymus
endoderm
