These cells get nutrients through simple diffusion. Diffusion allows substances to move between each other, and nutrients diffuse into the cells of the sponge.
i want to know the answer may u please just tell me it thank you a lot my email is joliris11@aol.com send it at soon asap
O2 is dissolved in the ocean,
food is mostly bacteria, caught as it drifts past each cell.
By filter feeding -- water is brought into the sponge's central cavity via its pores and is propelled out by its osculum.
Goblet cells
The cells that makes mucus are called goblet cells. These are glandular simple columnar epithelial cells that secrete gel forming mucins, which are the major component of mucus.
which are unicellular glands
You may be thinking of the sublingual gland. But there are many mucus secreting cells embedded in the epithelium of various tissues (such as intestinal tract, female reproductive tract, etc.)
The circulatory system is responsible for transporting essential nutrients throughout the body. It picks up the nutrients from the small intestine and large intestine, and brings the nutrients to cells in the body.
Nutrients can be dispersed to all the cells of a sponge because they can change their function. Sponges are very abundant and can even be found in freshwater.
They improve both respiratory and digestive functions for the sponge, pulling in oxygen and nutrients and allowing a rapid expulsion of carbon dioxide and other waste products.
Goblet cells
Water is usually part of any biochemical reaction.Water is an essential component to blood which circulates essential nutrients to cells and removes wastes and toxins.
The cells that makes mucus are called goblet cells. These are glandular simple columnar epithelial cells that secrete gel forming mucins, which are the major component of mucus.
The goblet cells are found and scattered among the other cells in the epithelium.
archeocytes
Proteins
Goblet cells are not dangerous; they are a normal part of human anatomy.
which are unicellular glands
Goblet cells secrete mucus, a viscous fluid composed primarily of highly glycosylated proteins called mucins suspended in a solution of electrolytes.Goblet cells.
