Invertebrate Phylum: (Sponges) PORIFERA
Vocabulary Porifera = "pore-bearing”; eat, excrete, & reproduce through pores ostia = pores for water to enter osculum = pores for water to exit
Vocabulary collar cells = cells to move water and catch foodspicules = calcium carbonate or silica skeleton amoebocytes = cells that digest, store, and transfer food
Characteristics * Asymmetrical body plan * Brown/gray to red* Tubes with channels and chambers * Specialized cells
Reproduction * Sexual - produce egg and sperm (cross and self fertilization) Larvae with flagella attaches and grows * Asexual - budding and regeneration
Habitat * Aquatic (marine and fresh water)* Sessile-adults are nonmotile Vase Sponge Tube Sponge
Uses Cleaning and bathing aid Cancer curing toxinProtect small fish and sea animals
Osculum Epidermal Cells Spongocei Choanocyte Spicule Pore Cell Amebocyte Mesenchyma
Sponges Phylum Porifera.
Sponges. Classification: Domain Eukarya Kingdom Animalia Phylum Porifiera – due to its pores * More than 7,000 named species *The rest of a sponge’s classification.

The simplest animal Invertebrates No symmetry Live in water all over the world Depend on water for food, oxygen, and reproduction.
Collar cell Ostium Osculum Spicule ? Ostium What happens at the osculum? Water exits.
Invertebrate Notes. Sponges- Porifera “Pore Bearer” Show examples Evolutionary sideline - alone. Simple multicellular animals lacking true tissues.
What is a sponge? Sponges are asymmetrical aquatic animals that have a variety of colors, shapes, and sizes.
Phylum: Porifera Sponges
Big ideas The process of evolution drives the diversity and unity of life. Biological systems utilize free energy and molecular building blocks to grow,
Ch. 35 Porifera Invertebrates Animals without a backbone 97% of all species Simplest is sponge.
Comparing Invertebrates. Metazoans Also known as Kingdom Animalia –Multi-cellular –Develop from embryos –Divided into two groups based on the presence.
The Sponges. General Characteristics Porifera means “full of holes” Sponges are the simplest of animals Live in both freshwater and saltwater.

Phylum Porifera A.K.A.Sponges. Sponges are an animal?? Yes, they are!!! Yes, they are!!! Sessile- sponges do not move; anchored to one place (rock or.
Phylum Porifera Sponges. PHYLUM PORIFERA Sponges oldest of all animals few specialized cells sessile – can’t move.
PORIFERA Kingdom : Animalia Phylum : Porifera Porifera = “pore bearer” Pink lumpy sponge Yellow barrel sponge.
Invertebrate Animals Sponges.
Phylum Porifera Sponges. Porifera Sponges – Living on Earth for at least 540 million years – Most sponges live in the ocean Arctic to the tropics shallow.
