Across
3
Class of cnidaria including jellyfish which exhibits a 2-stage life cycle
5
Tiny pore through which water and food particles are pulled int the porifera body
9
Cluster of viable porifera cells encased in a spicule-reinforced coat which may survive if individual sponge dies.
11
Primitive nervous system connection within cnidarians which enable tentacles and tubular body structure to coordinate feeding motion or response to stimuli.
12
Mode of reproduction in some cnidarians in which a small group of cells develop into a growing "mini-me" off the side of an individual then break off to form another complete organism (a clone of itself)
14
Internal body cavity of most cnidarians where digestion and circulation of nutrients occur
15
Stinging cells lining the tentacles of many cnidarians
18
Phylum including jellyfish
20
Mobile cells within the mesenchyme of porifera which may serve many functions from producing the spicules to transporting nutrients and waste products
21
Layer of cells lining the gastrovascular cavity
22
The jelly-like layer separating the epidermis from the gastrodermis (the goo in the middle)
23
Capsules with poisonous barbs which are released or propelled into prey or predators and facilitate capture and ingestion of small invertebrates
Down
1
Large opening through which water and waste are pumped out of the porifera body
2
Mineral (silica or calcium carbonate) or proteinaceous network of fibers giving structure to an otherwise blob of an organism
4
These flagellated cells line the body cavities of poriferans, help generate the water current, and capture food particles for digestion.
6
Mode of reproduction in which aan organism can be cut or divided, and a complete individual may regrow from each of the pieces
7
Bell-shaped body plan with tentacles of some free-swimming cnidarians
8
Body form consisting of two- muscle layers surrounding a fluid filled interior. Contraction of the muscles forms a rigid tube and offers structural integrity for the organism.
10
Outer layer of cells in sponges (and many animals)
13
Cup-shaped tubular body plan of some cnidarians which feature tentacles and mouth on one end (for feeding), and a basal disc on the other end (for attachment to substrate)
16
Phylum including sponges
17
Non-cellular jelly-like matrix between cell layers in porifera body plan
19
Class of cnidaria including Sea Anemones which exist as single individuals within a self-made mineral cup, or as colonial polyps forming large "flower-like" structures.
