Leuconoid

-most complex body form in sponges -gemmules -label incurrent canals, excurrent canals, choanocyte chambers, osculum -ostia = pores -Spongilla & Anheteromeyenia

Volvulent

-nematocyst -wrap around prey/spine -darker, coils & a head -many of them -hydra released when eating

Asconoid

Sac/Bag-Like Inside lined with choanocytes Simplest Body Plan Terminal osculum Ostia = pores Phylum Porifera -Leucosolenia

Phylum Cnidaria

cnid = nettle -cnidocytes: cell that contains the stinging structure -nematocysts: stinging structure -cnidocil: shoots nematocyst out if touched (fastest movement in animal world) 1. alternation of generations -polyp -medusa 2. radial symmetry

Agranulocytes

lymphocytes and monocytes -monocyte: C-shaped nucleus -lymphocyte: round nucleus

Granulocytes

neutrophils, eosinophils, basophils -eosinophils: red granules in cytoplasm (acidic) -neutrophils: purple granules (neutral) -basophils: blue granules (basic)

Porifera

pore bearing -loose aggregation of cells -mesophyl: like bones -amoebocytes: secrete spicules (digestive system)

Connective Tissue

living cells surrounded by non-living material (matrix)

Syconoid

-like a folded bag -label incurrent canal, radial canal, choanocytes, pinacocytes, ostium, apopyle, osculum, spongcoel -prosopyles = pores -increases surface area -Scypha or Grantia

Elegance coral

-look at picture from case

Glutinant

-look up picture -nematocyst -clear/lighter w an oval head -sticky to hold on to prey -hydra released when eating

Spongilla Phylum Porifera Class Demospongiae -Leuconoid -gemmules -freshwater -spicules -contain cells to build new sponges (for winter/hard times) -asexual reproduction -specimen

*look at Anheteromeyenia preserved specimen for another Leuconoid sponge

Microscope Question

1. put slide on stage 2. raise stage completely, using coarse adjustment knob 3. look through oculars 4. use the course adjustment knob to lower the stage until the slide comes into focus 5. "fine tune" with the fine adjustment knob 6. stop looking through oculars 7. rotate 10x objective into place 8. look through oculars 9. "fine tune" with the fine adjustment knob 10. stop looking through oculars 11. rotate 4x (scanning) lens into place 12. lower stage completely, using coarse adjustment knob 13. take slide off stage A, J, C, K, G, D, F, C, G, D, E I, B
