mesoderm
The fate of archenteron is that it develops into alimentary canal, and the digestive system organs in higher animals.
The archenteron, which develops into the digestive system of an animal, is formed during gastrulation, the process by which the cells of a blastula are partitioned into three separate germ layers.
Each animal species has its own digestive system suited for its own needs, diet, and enviroment. Adaptation and evolution has changed the animals digestive system for its own benifit.
No, not all organisms start out as embryos. Embryos are typically seen in higher animals that undergo sexual reproduction, where a fertilized egg develops into an organism. Organisms like bacteria and protists reproduce asexually and do not have an embryonic stage in their life cycle.
Animalia is the scientific kingdom that all animals are classified under. Organisms in this kingdom are multi-cellular and have digestive tracts.
In plants embryo develops in new seedling and in animals it develops into feotus which later develops into baby
Amphibians do not have outer covering.
Animals are not prokaryotes.They are eukaryotic organisms.
yes animals are organisms :) *<:[}
No. plants do not digest food, they make their own from sun-light, water, CO2, and soil minerals. Plants don't need a digestive system. Animals, in other words, do.I think plants are the only organisms that don't have a digestive system. Many species of the Protists never developed a digestive system. Some unsegmented worms that have taken up a parasitic livelihood (such as Hook Worms and tape worms) have lost what digestive they once had and absorb their nutrients directly through their skin.
Many marine animals have a shell covering. A few of these animals are snails, shellfish, crabs, tortoises, turtles, and the like.
Multicellular organisms that have cells containing nuclei and absorb nutrients from their surroundings after breaking them down with digestive juices are called multicellular eukaryotes. These organisms include animals, fungi, and some protists. They use various methods, such as ingestion, to take in food and enzymes to break it down for absorption by their cells.
