3. Multicellular Eukaryotic Have no cell walls Have cells that transmit messages. Characteristics

4. Q42. In you observation, how are animals distinguished from the other groups as to their reaction to stimuli?

5. Invertebrates – without backbones Vertebrates – with backbones 2 Big Groups of Animals

6. Sponges Cnidarians Flatworms Roundworms Segmented worms Mollusks Echinoderms Arthropods INVERTEBRATES

7. Simplest animals Live in shallow and deep ocean Young sponges are motile, adults are attached to rocks b elong to Phylum Porifera SPONGES

8. Body is supported by a “skeleton” called spicules . used for bathing and washing. SPONGES

9. Waste water and materials go out of the sponges through the osculum . SPONGES

10. SPONGES (Examples)

11. SPONGES (Examples)

12. b elong to Phylum Cnidaria Tentacles contain stinging ceslls called nematocysts . CNIDARIANS corals jellyfish hydra

13. These poison-filled structures are used for defense and to capture their prey. CNIDARIANS

14. CNIDARIANS (Examples) hydra H ydra represents freshwater cnidarians

15. CNIDARIANS (Examples) jellyfish

16. CNIDARIANS (Examples) corals Corals form colonies and secrete hard skeleton

17. CNIDARIANS (Examples) Corals form colonies and secrete hard skeleton . These accumulate to form coral reefs. Coral reef is where fishes and other marine organisms breed.

18. b elong to Phylum Platyhelminthes Flat and ribbon-like organisms Found in freshwater, in wet places and marine waters. FLATWORMS

19. FLATWORMS (Examples) planaria tapeworm

20. FLATWORMS (Examples) Planaria is an example of a free-living flatworm. It lives in moist surfaces, under rocks in ponds, rivers and even aquariums.

21. FLATWORMS (Examples) Tapeworms are also parasitic flatworms like flukes without a digestive system.

22. b elong to Phylum Nematoda Also known as nematodes Have long cylindrical and slender bodies ROUND WORMS ascaris

23. Decomposers in soil in both marine and freshwaters. Other examples include heartworm, trichina worm, hookworm, pinworm ROUND WORMS

24. b elong to Phylum Annelida Also known as annelids Characterized by a segmented or repeated body parts. Ex. Earthworms, polychaetes , leeches SEGMENTED WORMS

25. Annelids have nervous, circulatory, digestive and excretory systems. Gas exchange only occurs through diffusion. SEGMENTED WORMS

26. earthworms leeches

27. Most polychaetes are marine living in tubes attached to rocks or sand. They get floating food through their feathery gills. Example: sandworms Polychaetes

28. Are blood-sucking annelids. They have suckers that are also attach themselves to their hosts. They secrete an ati -clotting chemical that has been used in medicine. Leeches
