All You Need To Know About Sponges
Sponges are mostly found in the sea. They are very simple invertebrates with no eyes, heads, tail, or mouth. Their body is made in such a way that it contains holes, which are referred to as pores. When they want to feed, they do that by pumping water through their pores to distill some particles of food. These animals come in varying colours.
You can find them as purple, blue, orange, and so many other colours. They are a multicellular animal made of different compositions. One thing about these animals is that they have false tissues, which are partially formed. The tissues are not tissues in the real sense.
They also do not have a circulatory or nervous system. As such, they do not function the way regular animals would. There are a lot of different features these animals have that you won’t find in others. This makes them unique in their own way. Their structure is quite a simple one.
The head is affixed to a solid, which can be a rock while the other end is left open to the environment. These animals are made of four cells and that’s why they are referred to as multicellular. Although the cells are many, they are independent and simple, which makes the animals have a simple structure as well.
The first cell to note is the collar cell, which is one of the crucial cells holding the animal together. The collar cell has a core function, which keeps the sponge adequately functioning without complications. The flagella gets attached to this cell and that helps with pumping of water to the animal’s body. By so doing, nutrients and oxygen are brought closer to the animal, and this goes a long way in sustaining it.
The second cells to note are the porocytes. These are the cells responsible for the pores on the sponge’s body. These cells are crucial because the pores are essential to the living and feeding of the animal. Without the pores, the sponge might be unable to feed. This makes these cells highly essential as a part of the sponge’s formation.
Epidermal cells are the cells that formulate the sponge’s skin. These are the cells offering a decent level of protection. With the cells, the sponge not only has a skin that allows it to function, but one that also keeps it protected at all times. Without this cell, the sponges cannot be formed.
The last ones are the amoebocytes, which are the cells responsible for the transporting of nutrients. For nutrients to move from one place to another. These are the cells through which that is done. The cells are located between the collar cells and the epidermal cells. By facilitating the transportation of nutrients, the cells essential to the growth and development of the sponge.
Sponges can survive in many kinds of environments. This accounts for why they are found in many seas across the world. Nearly all sponges live in the sea.
