Unit 6 – Lecture 7
Kingdom Animalia Animals Are: eukaryotic multicellular sexually reproducing mostly some have asexual reproduction
Kingdom Animalia Animals Have: have no cell wall have specalized cells
Kingdom Animalia Animals Have: most have tissues tissue – groups of specilized cells that work together as a single unit. examples: heart, lung, skin…etc organs are made of tissues
Symmetry Asymmetry non-symmetrical most are sessile sessile – non-moving ex: sponges
Symmetry Radial Symmetry symmetrical from the center out develops from 2 layers of cells 2 OR 3 layers of tissues ex: starfish, jellyfish, etc.
Symmetry Bilateral Symmetry bi = two, lateral = refers to side symmetrical along a median line develops from 3 layers of tissues ex: most commonly chordates
Phylum Porifera ex: sponges, aka pore-bearers asymmetrical [or radial] – sessile 2 layers of cells – no tissues no body cavity
Phylum Porifera get nutrients thorugh filter feeding
Phylum Porifera reproduces sexually with gametes asexually using gemmules [like budding] asexually using fragmentation respires through diffusion
Phylum Cnidaria jellyfish, hydras, anemone, coral…etc aka stinging-celled organisms Cnidarians Have: radial symmetry 2 layers of tissues simple nervous system senses chemical smells & touch
Phylum Cnidaria Cnidarians Have: 2 body forms
Phylum Cnidaria ingestion using tentacles nematocysts – small, harpoon-like stinging cells inside of cnidocytes
Phylum Cnidaria Cnidarians Have: digestion using gastrovascular cavity gastro = stomach gastrovascular cavity – singular cavity which includes digestion and respiration
Phylum Cnidaria reproduce sexually with gametes asexually using budding immortal jellyfish?? respires using diffusion
HW: Finish Porifera/Cnidaria pages for tomorrow read the Cnidaria worksheet
Kingdom Animalia Sponges Cnidarians Flatworms Roundworms.
Sponges Cnidarians Ctenophores. Phylum Porifera: The Sponges.
Phylum Cnidaria. Cnidarians have special stinging cells called cnidocytes. They have long flexible tentacles and usually live in sea water. Because they.
Sponges Phylum Porifera. SPONGES ARE STRANGE Only meet MINIMUM requirement for Kingdom Animalia –Multicellular, eukaryotic cells, heterotrophic, moves.
Phylum Porifera. The word porifera originates from Latin and refers to the organism having a body full of _____. It literally means "pore bodied" or "pore.
Cnidarians Jellies, Anemones, Corals Jellies, Anemones, Corals Dimorphism: Two body shapes during life cycle. (Polyp & Medusa) Dimorphism: Two body shapes.
INVERTEBRATES CH Kingdom Animalia Major Characteristics= eukaryotic, multi-cellular, heterotrophic, lack a cell wall Invertebrates Include 95-97%
Phylum Cnidaria All contain nematocysts- stinging structures.

CHAPTER 26 Sponges, Cnidarians, Flatworms, and Roundworms.
Kingdom Animalia. ~ Characteristics ~ Multicellular Multicellular Eukaryotic with no cell walls Eukaryotic with no cell walls Heterotrophs (consumers)
Simple Invertebrates Sponge Sponges are asymmetrical and do not have real tissue or organs. Cnidarians have radial symmetry and have a mouth, tentacles,

Sponges Phylum Porifera. Phylum Porifera – Pore Bearers Water flow Choanocyte Spicule Pore cell Pore Epidermal cell Archaeocyte Osculum Central cavity.
Section 26.1 Summary – pages Sponges are asymmetrical aquatic animals that have a variety of colors, shapes, and sizes. Many are bright shades.
Introduction to Animals. Over a million different types have been identified! Animals likely evolved from protozoans. Kingdom Protista.

Kingdom Animalia. Animals are defined as: Heterotrophic (not making their own food) multi-cellular Having eukaryotic cells Having cells with no cell walls.
Animals Chapter 32. Characteristics of the Animal Kingdom 1)Multicellular 2)Heterotrophic 3)Sexual Reproduction and Development (Most reproduce sexually)
