|---|---|---|---|---|---|
| A hypothesis formulated to explain the origin of multicellularity from protis ancestors. Animals may have been derived when protists associated and cells became specialized and interdependen. | Colonial Hypothesis
🗑
|
||||
| The idea that multicellular organisms could have arisen by the formation of plasma membranes within a large, multinucleaste protists. | Syncytial Hypothesis
🗑
|
||||
| Thin, flat cell covering the outher surface, and some of the inner surface of poriferans. | Pinacocytes
🗑
|
||||
| Tubular cells in sponge body wall that create a water channel to an interior chamber. | Porocytes
🗑
|
||||
| A jellylike layer between the outer and inner layers of a sponge. Contains wandering amoeboid cells. | Mesohyl
🗑
|
||||
| Amoeboid cells within the mesohyl of a sponge. Mesenchyme cells are specialized for reproduction, secreting skeletal elements, transporting food, storing food, and forming contractile rings around openings in the sponge wall. | Mesenchyme cells
🗑
|
||||
| Cells of sponges that create water currents and filter food. | Choanocytes
🗑
|
||||
| Skeletal elements that some mesenchyme cells of a sponge body wall secrete. May be made of calcum carbonate or silica. | Spicules
🗑
|
||||
| A fibrous protein that makes up the supportive framework of some sponges. | Spongin
🗑
|
||||
| The simplest of the three sponge body forms. These sponges are vaselike, with choanocytes directly lining the spongocoel. | Ascon
🗑
|
||||
| A sponge body form characterized by choanocytes lining radial canals. | Sycon
🗑
|
||||
| The sponge body form that has an extensively branched canal system. The canals lead to chambers line by choanocytes. | Leucon
🗑
|
||||
| The immature stage of the sponge in which the adults and immatures are different in body form and habitat. | Larva
🗑
|
||||
| Resitstant, overwintering capsule formed by freshwater, and some marine, sponges that contains masses of mesenchyme cells. Amoeboid mesenchyme cells are released and organize into a sponge. | Gemmules
🗑
|
||||
| A sheet of cells covering the surface of an animal's body. | Epidermis
🗑
|
||||
| The endodermally derived lining of the gastrovascular cavity of Cnidaria. | Gastrodermis
🗑
|
||||
| A gel-like matrixs between the epidermis and gastrodermis of cnidarians. | Mesoglea
🗑
|
||||
| An organelle charactristic of the cnidaria that is used in defense, food gathering, and attachment. | Cnida
🗑
|
||||
| The cells that produce and discharge the cnidea in members of the phylum Cnidaria. | Cnidocytes
🗑
|
||||
| A cnidarian cnida usually armed with spines or barbs and containing a venom that is injected into a prey's flesh. | Nematocysts
🗑
|
||||
| Usually, the sexual stage in the life cycle of cnidarians. The jellyfish body form. | Medusa
🗑
|
||||
| The attached, usually asexual, stage of cnidarian. | Polyp
🗑
|
||||
| The use of body cavity fluids, confined by the body wall, to give support. | Hydrostatic Skeleton
🗑
|
||||
| A ciliated free swimming larva of most cnidarians. This develops following sexual reproduction and metamorphoses into a polyp. | Planula
🗑
|
||||
| A feeding polyp in a colonial hydrozoan. | Gastrozooid
🗑
|
||||
| A polyp of a hydrozoan cnidarian that produces medusea. | Gonozooid
🗑
|
||||
| A structure that hangs from the oral surface of a cnidarian medusa and surrounds the mouth. | Manubrium
🗑
|
||||
| An organ of equilibrium and balance in many invertebrates. They usually consist of a fluid-filled cavity containing sensory hairs and a mineral mass called a statolith. | Statocyst
🗑
|
||||
| A sensory structure at the margin of the scyphozoan medusa. It consists of a staocyst and a photoreceptor. | Rhopalium
🗑
|
||||
| The polyp stage of a scyphozoan. | Scyphistoma
🗑
|
||||
| Miniature medusa produced by asexual budding of a scyphistoma. They develop into sexually mature medusa. | Ephyrae
🗑
|
||||
| The condition in a hermaphrodite in which male gonads mature before female gametes. Prevents self fertilization. | Protandry
🗑
|
||||
| Rows of cilia that are the locomotor organs of ctenophorns. | Comb Rows
🗑
|
||||
| Adhesive cells on ctenophoran tentacles for capturing prey. | Colloblasts
🗑
