Kingdom Animalia
* Are made of animal cells * No cell walls * Eukaryotic. Lysosomes, centrioles. Flagella, cilia * Multicellular * Heterotrophic * Chemotrophic * They are either: 1. Invertebrates * Have no back bone 2. Vertebrates
Things to classify Animals: 1. Feeding 2. Respiration 3. Internal Transport 4. Excretion 5. Response 6. Movement 7. Reproduction
Phylum Porifera * The flagella move water into the sponge * Cells collect nutrients in the water before it leaves the sponge * Internal transport> have cells like amoeboids to crawl around; hands out nutrients 1. Reproduction * It is a hermaphrodite * Can do budding (Asexual) * Sexual reproduction * Keeps eggs inside and send out millions of sperm 2. Response * Does not usually respond 3. Exertion * Pees in the water 4. Movement * Does not move 5. Feeding * Drinks water and filters for nutrients 6. Internal Transport * Importance: * Homes for marine fish and worms
Trends in Animals * More complex, specialized cells which form tissues and organs * Radial>bilateral symmetry * Cephalization is the centration of sense organs in the anterior region * The rear end is the posterior * The Dorsal is the back * The ventral is the front
Phylum Cnidaria * Example jellyfish * Have two forms * * * Tentacles have nematocysts which are poisons filled sacs with a coiled needle * Mouth is entrance and exit. Many jellyfish have symbiosis with photosynthetic protists. Jellyfish have no brains but have a simple reserve net to coordinate tentacle movement. * Many also have photoreceptors so they can swim towards the light * For reproduction, they do external fertilization * They have a very simple nervous system * Gastro vascular cavity is a method for
