Cnidaria. General Information  Eumetazoans  (true animals) all animals other than sponges-have both tissues and symmetry  When eumetazoans develop-they.

Phylum Cnidaria. General Characteristics They are radially symmetrical They have 2 tissue layers: Epidermis - Outer layer of cells Gastrodermis Inner.

Otherwise known as “Cool Coral and Friends!”.  Common Characteristics ◦ Live in water ◦ Stinging cells (nematocysts) to capture prey and defend themselves.

Presentation transcript:

Chapter 9.3 Sponges and Cnidarians

POINT > Describe characteristics of sponges POINT > Describe characteristics of a cnidarians POINT > Describe two stages of cnidarian life cycle POINT > Emphasize the importance of coral reefs

POINT > Describe the characteristics of sponges Sponges are the simplest animals Cellular level of organization (no tissues or organs) No symmetry Live in fresh and salt water Water flows in through the cells and out through the top. Single-celled organisms are filtered out of the water for food

POINT > Describe the characteristics of sponges Choanocytes are cells that move water through the sponge Sponges reproduce both asexually and sexually

CHECK: What kind of symmetry do sponges have? What level of organization to sponges have? What are choanocytes? Where do sponges live?

POINT > Describe characteristics of cnidarians Cnidarians include jellyfish, hydra, anenomes and corals

POINT > Describe characteristics of a cnidarians Cnidarians have radial symmetry Tissue level of organization: simple nervous and muscle tissue Have stinging cells called nematocysts for capturing prey Have a mouth and digestive cavity to eat prey Reproduction is both sexual and asexual (budding)

POINT > Describe two stages of cnidarian life cycle Cnidarians have a two-stage life cycle: 1. Polyp – lives attached to rock or lake bed

POINT > Describe two stages of cnidarian life cycle Cnidarians have a two-stage life cycle: 2. Medusa – free swimming

POINT > Describe two stages of cnidarian life cycle

CHECK: What type of symmetry to cnidarians have? What are 3 types of cnidarians? What are the two stages in cnidarian life cycles? What are nematocysts?

Polyp or medusa?

Coral reef

POINT > Emphasize the importance of coral reefs Corals are cnidarians that live in colonies Coral reefs are made of the dead skeletons of the coral Coral reefs provide habitat for fish and other organisms in the oceans Most of the oceans’ biodiversity exists in coral reefs

POINT > Emphasize the importance of coral reefs Coral reefs are being destroyed rapidly by pollution, over- fishing and increases in water temperatures and acidity Large reefs in the Caribbean and South Pacific ocean have experienced 40-90% loss over the past 10 years
