- Slides: 31
Phylum Porifera
I. General Information • Kingdom : Animalia • Phylum : Porifera • Porifera = “pore bearer” Yellow barrel sponge Pink lumpy sponge
I. General Information Size range – 1 cm to 2 meters in diameter Giant Barrel sponges
II. Body Structure A. Ostia – pores – many, water IN B. Oscula – large opening(s), one or few, water OUT osculum
II. Body Structure C. Choanocytes – collar cells; have flagella D. Amoebocytes – transport food to layer of cells not on the surface
II. Body Structure E. Spicules – “skeleton” hard splinterlike; made of calcium carbonate (Ca. CO 3) or silica (Si) F. Spongin – flexible protein
III. Level of organization A. Cellular B. Eukaryotic C. No tissues Japanese Deep Sea Sponge
IV. Symmetry A. Some asymetrical B. Some radial
V. Habitat Aquatic A. Marine and B. Fresh-water Purple Rope sponge Fresh-water Sponge
VI. Feeding • • • Heterotrophic Filter feeders Food trapped by choanocytes Intracellular digestion (within the cell) No digestive tract
VI. Feeding – – Water & food goes in via ostia Choanocytes trap food in spongocoel Amoebocytes carry food to inner layer of cells Water out osculum
VII. Respiration - via diffusion
VIII. Internal transport • via diffusion
IX. Excretion Via DIFFUSION!!!!!
IX. Response • NONE ! • No Nervous System • No cephalization Pipe organ sponge
X. Locomotion = movementor motility Larvae Freeswimming, use cilia Adults Sessile (do NOT move)
XI. Reproduction 1. Asexual a. budding b. gemmules formed in stress conditions
XI. Reproduction • • 2. Sexual a. Most monoecious = both sexes in same organism (hermaphrodites) egg & sperm produced cross fertilization egg + sperm => free-swimming larvae
XI. Reproduction 2. Sexual b. Some dioecious • Separate sexes • Egg OR sperm produced Sponge releasing sperm
XII. Ecological Roles A. Habitat for other aquatic animals B. Food for some
XII. Ecological Roles C. Home use: bathing, cleaning, home improvement, other
XII. Ecological Roles D. Medical research Sponges do not get cancer Why not? Maybe we can use what keeps them from getting cancer to treat humans………. .
