Blastula

early animal embryonic development that produces the blastula. In mammalian development the blastula develops into the blastocyst with a differentiated...

yolk-filled cavity that forms in the blastula during very early embryonic development. At this stage in mammals the blastula develops into the blastocyst containing...

The morula develops into a structure called a blastula through a process called blastulation. The blastula develops into a structure called a gastrula through...

stage in the early embryonic development of most animals, during which the blastula (a single-layered hollow sphere of cells), or in mammals the blastocyst...

folding of an area of the exterior sheet of cells towards the inside of the blastula. In each organism, the complexity will be different depending on the number...

holoblastic or meroblastic depending on the species. During gastrulation, the blastula develops in one of two ways that divide the whole animal kingdom into two-halves...

embryo, it continues dividing into a hollow sphere of cells, which is a blastula. These outer cells form a single epithelial layer, the blastoderm, that...

occurs during the blastula stage of embryonic development in non-mammals. During this stage, the embryo is referred to as a blastula. The series of changes...

to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals. The mammalian blastocyst hatches before implantating...

blastocoel The fluid-filled or yolk-filled cavity that forms in the developing blastula or blastocyst in virtually all animal species. The blastocoel appears to...

move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they...

protostomes, a zygote first develops into a hollow ball of cells, called a blastula. In deuterostomes, the early divisions occur parallel or perpendicular...

embryo has divided into many cells, forming a hollow ball called the blastula. The blastula is polar, and its two halves are called the animal hemisphere and...

and develops into a free-swimming blastula embryo in as few as 12 hours. Initially a simple ball of cells, the blastula soon transforms into a cone-shaped...

Diploblasty is a condition of the blastula in which there are two primary germ layers: the ectoderm and endoderm. Diploblastic organisms are organisms...

Animal Name of larvae Porifera (sponges) coeloblastula (= blastula, amphiblastula), parenchymula (= parenchymella, stereogastrula) Heterocyemida Wagener's...

structure consisting of an undifferentiated ball of cells and is called a blastula. In humans, blastocyst formation begins about five days after fertilization...

at the blastula stage, and are incorporated into the gonads during organogenesis. The germ layers form during the gastrulation of the blastula. The term...

mitotic cell divisions transform the zygote into a hollow ball of cells, a blastula. This early embryonic form undergoes gastrulation, forming a gastrula with...

of the zygote after fertilization; blastomeres are an essential part of blastula formation, and blastocyst formation in mammals. In humans, blastomere formation...
