Sri Lanka - Sri Lanka - Plant and animal life: Sri Lanka’s natural vegetation covers about one-third of the total land area. The climax vegetation (i.e., natural vegetation permitted to develop uninterrupted) in most parts of the country is forest. In the Wet Zone, tropical wet evergreen forest dominates in the lowlands, and submontane and montane evergreen forests prevail in the highlands.

Fertilization and Early Embryonic Development | Boundless

Fertilization. Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes.

Summary The early stages of embryonic development begin with fertilization. The process of fertilization is tightly controlled to ensure that only one sperm fuses with one egg. After fertilization, the zygote undergoes cleavage to form the blastula.

Fertilization - Embryology

Fertilization is the fusion of haploid gametes, egg and sperm, to form the diploid zygote. Note though there can be subtle differences in the fertilization process which occurs naturally within the body or through reproductive technologies outside the body, the overall product in both cases is a diplod zygote. In fertilization research, after humans the mouse is the most studied species
