Reproduction
Reproduction types
Sexual reproduction
Hermaphroditism,Binari fussil,
Asexual reproduction
Fission, Budding,Parthenogenesis
TISSUES AND ORGANS MADE OF ECTODERM, MESODERM AND ENDODERM
Ectoderm-nerveous system,sensory receptors in epidermis
Mesoderm-skeletal system,dermis of skin
Endoderm-liver,pancreas
GAMETOGENESIS
SPERMATOGENESIS
1.Multiplication-Primary spermatocyte is produce two cells:mitosis
2.Growth phase-primary spermatocyte increase in size
3.Maturation-secondary spermatocyte after meiosis1 amd spermatid after meiosis2
4.Formation-mature sperm cells head, neck,middle piece and tail
OOgenesis
1.Multiplication-fetal development born oogonium and primary oocytes
2.Grown-primary oocytes increase in size
3.Maturation-after puderty
Cells: Before Birth-Oogonium Diploud 2n
After Puberty:Secondary oocyte haploid-n
Fertilization
Actorosomal reaction
reaction is the release of enzymes and other substances from the acrosome, a sac-like structure on the head of the sperm
Cortical Reaction
process initiated during fertilization that prevents polyspermy, the fusion of multiple sperm with one egg.
Human Embyrogenesis
Stage
It encompasses the first eight weeks of development after fertilization, in which a single cell formed at fertilization turns into an organism with a multi-level body plan.
he morphogenic events during this period include fertilization, transportation of zygote through the uterine tube, mitotic divisions/cleavage, implantation, and formation of primordial embryonic tissues.
METAMORPHOSIS
Complete metamorphosis
Complete metamorphosis is the type of insect development that includes egg, larva, pupal, and adult stages, which differ greatly in morphology. The lifecycle of butterflies, ants, fleas, bees, beetles, moths
Incomplete metamorphosis
refers to a type of insect development in which gradual changes occur in the insect during the development from the egg to the adult.
Mature gametes
