The control surface on a Poriferan is the surface that lines its internal canals and chambers. This surface is covered in specialized cells called choanocytes, which have flagella that create water currents to draw in food particles and oxygen for the sponge. The control surface plays a crucial role in nutrient exchange and waste removal in Poriferans.

What physical factors control the rate of chemical reactions?
Physical factors that control the rate of chemical reactions include temperature, pressure, concentration of reactants, and surface area of the reactants. Temperature influences the kinetic energy of particles, pressure affects the collision frequency of molecules, concentration determines the number of reactive collisions, and surface area determines the contact area between reactants.
What is surface area and how you can decrease or increase surface area?
Surface area refers to the total area that covers the surface of an object or structure. To decrease surface area, you can reduce the dimensions of the object or change its shape to be more compact. To increase surface area, you can add extensions, rough textures, or indentations to the object's surface.
Which covers more surface area a flat surface or a bumpy surface?
A bumpy surface covers more surface area than a flat surface because the bumps add extra surface area. This is due to the irregularities and protrusions on the bumpy surface that increase the overall area that comes into contact with other objects.
Who much of the substance is exposed on the surface?
The amount of substance exposed on the surface depends on the surface area of the substance. A substance with a larger surface area will have more exposed surface compared to a substance with a smaller surface area. Factors like particle size and shape can also affect the amount of substance exposed on the surface.
Why does a cell need to divide in terms of surface area to volume ratios?
A cell needs to divide because its surface area to volume ratio decreases as it grows larger. This impacts the cell's ability to take in nutrients and expel waste efficiently. By dividing, the cell can increase its surface area relative to its volume, allowing for better nutrient exchange.

How many cell layers compose a Poriferan?
A Poriferan typically consists of two cell layers: the outer epidermis and the inner layer of cells called choanocytes. These cells are separated by a gel-like matrix called mesohyl.
What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh

The surface area of a box when given the surface area height and peremeter?
It should be relatively easy to find the surface area of a box when you are given the surface area.
Is a coral a poriferan?
Corals are animals of the phylum Cnidaria, whereas:-Sponges are animals of the phylum Porifera.

Find the surface area?
It depends on the surface area of what!
How can you obtain a cell's ratio of surface area to volume?
To obtain the ratio of surface area to volume, divide the surface area by the volume.
