  1. 2. -a form of asexual reproduction where a new organism develops from an outgrowth or "bud" on the parent organism
  2. 4. -a sessile (non-moving) invertebrate form of a cnidarian, characterized by a hollow, tubular body attached at one end with a central mouth surrounded by tentacles
  3. 5. -a proteinaceous, collagenous skeletal fiber found in some sponges (phylum Porifera), providing a flexible, resilient framework that allows for water flow and support of their delicate tissues
  4. 6. -a free-swimming, bell-shaped, umbrella-like life stage of certain cnidarians, most famously jellyfish
  5. 9. - the immature, wingless form of an animal that looks significantly different from its adult stage, like a caterpillar or a fly maggot
  6. 11. -microscopic structural components of a sponge's skeleton, acting as support, a defense mechanism, and a means to filter water
  7. 12. -(of a plant or invertebrate animal) having the male and female reproductive organs in separate individuals.
  8. 15. -
  9. 16. - refers to the environment at the bottom of a body of water

  1. 1. -the large, central cavity found in the body of a sponge, through which water enters via numerous pores and then exits through a larger opening called the osculum
  2. 3. -having both the male and female reproductive organs in the same individual(of a plant or invertebrate animal)
  3. 7. animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms
  4. 8. -a large aperture in a sponge through which water is expelled
  5. 10. -the simplest body plan and canal system in sponges (Porifera)
  6. 11. -an immobile organism
  7. 13. -microscopic, drifting organisms in aquatic environments that range from bacteria to jellyfish
  8. 14. -an organism with both male and female reproductive organs
  9. 19. - a genus of calcareous sponges belonging to the family Sycettidae
  10. 20. whip-like appendages on microbes and cells that provide locomotion, enabling them to move through their environment
