Answers:firstly there is no word as phylums its phyla and secondly protozoa is not a phylum it actually refers to a class of organisms that existing from a long period and porifera is the phylum of sponges.coelenterata is the phylum of jelly fishes and all.annelida is the phylum for worms.molluscs are shelled creatures like shell fish,etc.echinoderms are starfishes.arthropods are mostly insects the name arthropod comes form greek arthropoda means jointed legs.and finally vertebrates are actually a sub phylum of chordates but vertebrates means group of organisms that have a vertebra and chordates are a group of organisms which have a notochord. hope you get the info and score well in your exams
Answers:> Few questions about the Phylum Mollusca? One of my favorite things. They don't fly! > Warm or cold blooded? Cold > Respiratory system type of organs does it change during lifetime? Hmmm. The general answer is no. But for some marine snails which have a larval stage, yes. > What habitat can you find this group in? Most, LOL. You'll find them in pretty much all marine and permanent aquatic environments. You'll find them in terrestrial environments where there's moisture, or moist places. > Do they migrate? I can't think of any that migrate. > Are they territorial? Most aren't. Some of the octopus species are. Some of the cuttlefish are territorial around breeding time. > How do they obtain food? Most bivalves are filter feeders. Most gastropods crawl around, and rasp food from surfaces with the radula -- you'll find detrivores, herbivores, and even carnivores doing this in this group. Cephalopods actively hunt and swim after prey. > Give an example of a food chain including these animals. Marine phytoplankton -> zooplankton -> clam Marine phytoplankton -> zooplankton -> small fish -> squid -> large fish Lettuce -> snail -> human being === > What type of reproduction is representative of this group? Sexual reproduction. Bivalves: external fertilization, eggs. Gastropods: internal fertilization. Some gastropods lay eggs, and others give live birth. Cephalopods: internal fertilization, lay eggs. > How many young at a time usually? Bivalves: thousands. Gastropods: the ones that lay eggs will lay somewhere between a dozen and a couple hundred at a time. The ones that give live birth have one at a time. Cephalopods: hundreds. > How often do they reproduce in a year? Bivalves: Hm, I don't know. Total guess: they reproduce about 26 times a year, timed by the tides. Gastropods: The ones that lay eggs will do so whenever they have some to lay. If the weather is good, every couple of weeks, I'd guess. The ones that give live birth will do so continuously in good conditions -- the adult Malaysian trumpet snails in my aquarium would give birth each and every day. Cephalopods: Once a year, I think.
Answers:1. There are 3 types of symmetry in the animal phyla in order of increased complexity: (Asymmetrical, Radial, and Bilateral) An example of an animal with asymmetry is the sponge under the Poriferan phylum because they come in different shapes and sizes. Radial symmetry found only in Cniderians like hydra or jellyfish. Bilateral symmetry - tunicates, humans, starfish, worms, clams, and grasshopper. 2. Heterotrophic organisms 3. Not to sure on that means... 4. Neural fold 5. Sponges are sessile, which means they stay attached to one place. They filter in water and nutrients through the water, as well as oxygen, so it doesn't have to move. It reproduces by budding, which means it grows a little sponge out of the side of it. 6. Bilateral 7. Calcarea (calcerous sponges - having spicules), Demospongiae (horn sponges, like the bath sponge), Scleropongiae (coralline or tropical reef sponges), and Hexactinellida (glass sponges). 8. Means an animal with openings in this case "pores" 9. Anthozoa (true coral, sea anemones, sea pens), Cubozoa (box jellyfish), Hydrozoa (freshwater hydra, fire coral), Scyphozoa (true jellyfish) 10. Spicules are the only primitive form of support in sponges. 11. I'm not too sure on what you mean by compounds... 12. Respiration: Incurrent pore (where water enters), Osculum also known as the outcurrent pore (where water leaves the sponge), this all occurs in the spongocoel (body cavity that involves water circulation and where nutrients get absorbed) Answer is Spongocoel. 13. Osculum 15. Haploid cell. 16. Choanocytes (These cells just "feed" the sponge) 17. Sponges can reproduce in two ways: sexually and asexually. in sexual reproduction, they release sperm into the water in hopes that it will land inside another sponge and fertilize an egg cell. all sponges are hermaphrodites, meaning that they can produce both egg and sperm, but they can't fertilize themselves. In asexual reproduction, a small sponge will grow off the side of the parent sponge in a process called budding. some species will bud internally by packing the new sponge cells into vessicles called "gemmules," which are released into the water when the parent sponge dies. all sponges that are produced asexually are exact clones of the parent sponge. 18.

Answers:Page 1 Contributed by: Ms. Kathy Fleiger Horton High School Kingdom Animalia Introduction General Characteristics of the Organisms in Kingdom Animalia 1. Animals are multicellular. 2. The cells of animals are eukaryotic and the cells lack cell walls. 3. Animals must obtain food from their environment. (Heterotrophic) Animals are not capable of photosynthesis. 4. Most animals are motile because of a nervous system and a muscular system. Three examples of animals that are sessile (stationary) feeders are sponges, mussels and barnacles. 5. Most animals reproduce sexually. 6. The two major groups within the animal kingdom are invertebrates and vertebrates. The invertebrates: The invertebrates include animals that have no backbone. Examples: sponges, worms, starfish, jellyfish, clams, and lobsters. The vertebrates: these are animals that do possess a backbone. Examples: fish, amphibians, reptiles, birds, and mammals. 7. In this kingdom the young usually have the same basic features as the adults. 8. Organisms in Kingdom Animalia usually display a defined shape or symmetry.
