A dormant mass of amoebocytes surrounded by protective layers of spicules is known as?
Gemmules
What are amebocytes?
Amoebocytes are cells that move using pseudopods and perform different functions in different animals .
A special kind of cell that builds spicules?
it is scleroblast cells which produce spicules which are modified amoebocytes
What is a list of the function of the amoebocytes and their reproductive function?
they have multiple functions, including the digestion of food particles and the transport of nutrients to other cells using the formation of pseudopodia for locomotion. The amoebocytes can also form skeletal fibers made of calcium carbonate called spicules.
How are the unique balls of the amoebocytes that are filled with a food supply and serve as protective reproductive structures called?
gemmules
Which group within kingdom protista probably gave rise to sponges?
Amoebas gace rise to sponges since the wall of sponges contain amoebocytes.
Produced by some freshwater sponges these food-filled balls of amoebocytes have protective coats that enable them to survive harsh conditions that may kill the adult sponge?
gemmules
What roles do amebocytes play in the anatomy of a sponge?
The Amoebocytes in sponges travel freely in the Mesenchyme. They digest food that the sponge has extracted from the water and transport the digested food to the parts of the sponge that need it.
How does a sponge breathe?
Sponges get oxygen by taking water through it's pores. The water moves over cells inside the sponge and oxygen in the water moves into the sponge's cells.
What do amoeba do?
An amoeba is a shapeless blob of ''jelly'' that engulfs random objects on its way to know where in particular. Amoeba move by using their pseudopodium which is a "false leg." Amoeba can be harmful or helpful to man-kind and other living things. Amoebas are composed of just one cell. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly. However, some amoebas do build shells. Amoebas move by making part of its body move in the direction it wants to travel. Then slowly the rest of the cell follows. In order to eat an Amoeba flows around other microorganisms and then engulfs them. To reproduce the Amoeba splits itself into two cells.
What is an example of a bacterial endotoxin test?
The Limulus amebocyte lysate (LAL) test is a test used to determine if a bacterial cell produces an endotoxin. ILimulus amebocyte lysate is an aqueous extract of blood cells (amoebocytes) from the horseshoe crab, Limulus polyphemus. LAL reacts with bacterial endotoxin or lipopolysaccharide (LPS), which is a membrane component of Gram negative bacteria.
What body type does phylum porifera have?
porifera is a multicelullar organism ,this has been a great achievement for these animals ,they have a body wall that is three layered namely epithelium this the outer part serves for protection ,mesohyale middle part contains amoebocytes which help in transportation of food and gastrodermis has the choanocytes which are the feeding cells 'collar cells' hope it helps sydney 3rd born
