Sponges are some of the earliest forms of animals. It lacks a gut (digestive cavity/system found in the majority of animals), a nervous system, and a circulatory system. Moreover, its structure, with a jelly-like mesohyl sandwiched by two thin walls of flattened cells, is unique. But what sets it apart from almost all other animals is the ability of some of its specialized cells to transform into other specialized cells (most other animals, like humans, only have unspecialized cells that differentiate into specialized cells which don't change functions).
What else can I help you with?
What animal looks more like a plant than a animal?
they are sponges
What kind of protection do sponges have?
Other than its skin, nothing.
What is the only animal phylum that does not have tissues and symmetry?
The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
Give at least Two features of sponges that convince biologist that sponges were really animal?
They reproduce with egg/sperm. They take in particles of food rather than perform photosynthesis.
Is a sponge an arthopod?
No, sponges are a completely different phylum group than arthropods.
What adaptations do sea sponges have other than poison?
Sea sponges don't have any other adaptations really. Its a very long and difficult to[pic. You should discuss it with an expert.
What are to unicellular phylum of animal kingdom?
The two unicellular phyla in the animal kingdom are Porifera (sponges) and Cnidaria (jellyfish, coral). These organisms consist of individual cells that work together to carry out essential functions, rather than being multicellular like other animals.
What function other than support might spicules nerve?
Spicules, most commonly found in the Phylum Porifera (sea sponges) provide support for the animal and defense against predators. Some studies have also been conducted that prove spicules to sort of act as light transmitting features on deep sea sponges.
Are sponges related to coral?
Sponges and coral have a lot in common. they just sit on rocks, filtering food particles, living in quite large colonies, and provide habitat for other animals. But, in a way, sponges and coral are totally different. Sponges and coral come from different animal phyla. Phyla is the most basic of all animal distinctions. sponges are among the most simple of all animals, not having true tissues and deterring predators primarily by their lack of nutrition. They are covered in little pores lined with cells with flagella which are used to circulate water through the sponge and take in food particles. Sponges can also live in very deep water. Corals are related to jellyfish and anemones. Even more conplex than sponges, they have differentiated tissue and a true gut. Corals look like single individuals but they are actually huge colonies made of many geneticaly idenical polyps just a few mm in diameter. these polyps have stinging tenticals, and instead of depending on food particals, corals get most of their nutrition from algae (the algae also gives them their color!) Corals can't live as deep as sponges can.
What organelles do plant cells have animal do not?
Lysosome ,Centriole, and VesicleActually, animal cells do not have any different organelles than plant cells, other than plant cells having a membrane. animal cells do not have a membrane, they have a cell wall.
Do all animals other than man have self consciousness?
No. There are animals without any nervous systems, like sponges.
What is the different between a animal cell and human?
Other than the specific human genome and resulting gene expression of the cell, there is no difference. Humans are simply one kind of animal.
