What class of sponges is Grantia in?

What class of sponges is Grantia in?

Calcareous spongeGrantia / ClassThe calcareous sponges of class Calcarea are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate in the form of calcite or aragonite. While the spicules in most species have three points, in some species they have either two or four points. Wikipedia

What phylum is Grantia?

SpongeGrantia / PhylumSponges, the members of the phylum Porifera, are a basal animal clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.

What kingdom is Grantia?

AnimalGrantia / KingdomAnimals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and Wikipedia

What are Grantia spicules?

Spicules are the mineral parts that form the skeleton of the grantia and are often composed of calcium carbonate or silica.

What is the shape of Grantia?

Shape, size, surface and consistency: Flat, like a small hot water bottle (Grantia compressa MCS2), but may be tubular, or composed of contorted flat lobes; with a very short stalk. Surface smooth, has a moderately high friction when stroked.

How do Grantia get rid of waste?

This group of sponges demonstrates the sycon body plan in which the wall of the colony is folded into a series of internal and external canals that circulate water to bring in dissolved oxygen and prey while removing waste products.

How does grantia reproduce?

Budding and fragmentation allows Grantia sponges to form identical offspring while sexual reproduction permits genetic mixing. Environmental conditions including water temperature, tidal stage, and the phase of the moon need to be near perfect or else sexual reproduction by these sponges is postponed.

How do Grantia reproduce?

Is grantia a sponge?

Sponges, colonial animals in the phylum Porifera, are primitive invertebrates that are dominated by marine species. Typically, they are benthic, sessile filter feeders that are asymmetrical. Grantia is a genus of calcareous marine sponges that is sometimes referred to as Scypha in older texts.

What type of body plan does the grantia have?

What is the shape of the grantia sponge?

Form: Flat, like a small hot water bottle, but may be tubular, or composed of contorted flat lobes; with a very short stalk. Colour: White or occasionally brown. Smell: None. Consistency: Moderately firm, can be bent through 180 deg.

What type of cells secrete spicules in Grantia?

The amebocytes secrete spicules of calcium carbonate in the gelatinous protein matrix of the sponge between the epidermis and the choanocytes. As diploblasts, sponges including Grantia exhibit only two germ layers, the endoderm and ectoderm.
