~ Characteristics ~ Multi-cellular Eukaryotic with no cell walls Heterotrophs (consumers) motile
Characteristics Cont.Animal Movement • Most animals are capable of complex and relatively rapid movement compared to plants and other organisms.
Animal Reproduction • Most animals reproduce sexually, by differentiated haploid cells (eggs & sperm). • Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material.
In addition toCharacteristics of Life 1. Living things are organized. 2. Living things are made up of cells. 3. Living things metabolize. 4. Living things maintain an internal environment. 5. Living things grow. 6. Living things respond. 7. Living things reproduce. 8. Living things evolve.
a mesozoan bluewhale Animal Sizes • Animals range in size from no more than a few cells (like the mesozoans) to organisms weighing many tons (like the blue whale).
Animal Habitats • Most animals inhabit the seas, with fewer in fresh water and even fewer on land.
Animal Cells • Animal cells, are eukaryotic • Animal cells lack the rigid cell walls that characterize plant cells.
Animal Bodies • The bodies of most animals (all except sponges) are made up of cells organized into tissues. • Each tissue is specialized to perform specific functions. Cells->tissues->organs->organ sys >organism
Animal Symmetry • Describes how animal body structures are arranged • Allows animals to move in different ways • Cnidarians and echinoderms are radially symmetrical. • Most animals are bilaterally symmetrical.
Symmetry: • The most primitive animals are asymmetrical: No symmetry
Radial Symmetry • forms that can be divided into similar halves by more than two planes passing through it. • Animals with radial symmetry are usually sessile, free-floating, or weakly swimming.
Bilateral Symmetry • Animals with bilateral symmetry are most well-suited for directional movement.
~ Protection and Support ~ • not all animals have a skeleton, divided into 2 groups: • exoskeleton – a hard, waxy coating on the outside of the body • endoskeleton – support framework within the body
~Invertebrates~ • No backbones • 95% of all animals are in this group
~Invertebrate Phylum Porifera~ • Sponges • simplest form of animal life • live in water • Do not move around • no symmetry • 5000 species
~Invertebrate Phylum Porifera~ • Examples: Tube Sponge, Glass Sponge, Sea Sponge
~Invertebrate Phylum Cnidaria~ • Live in water • Most have tentacles • catch food with stinging cells • gut for digesting
~Invertebrate Phylum Cnidaria~ • 2 different shapes • Medusa - like a jellyfish • Polyp - like a hydra
~Invertebrate Phylum Cnidaria~ • Examples - Jellyfish, Hydra, sea anemones, and corals
~Invertebrate Phylum Platyhelminthes ~ • Flatworms • Flat, ribbon-like body • Live in water or are parasites • bilateral symmetry
~Invertebrate Phylum Platyhelminthes ~ • Examples: Planaria • eyespots detect light • food and waste go in and out the same opening
~Invertebrate Phylum Platyhelminthes ~ • Examples: Tapeworm • Parasite that lives in intestines of host absorbing food
~Invertebrate Phylum Mollusca ~ • Soft bodies • Hard Shells • Live on land or in water • have a circulatory system and a complex nervous system. • Important food source for humans
~Invertebrate Phylum Mollusca ~ Class Gastropoda • snails and slugs • may have 1 shell • stomach-footed - move on stomach
~Invertebrate Phylum Mollusca ~ Class Bivalves • 2 shells hinged together • clams, oysters, scallops and mussels
~Invertebrate Phylum Mollusca ~ Class Cephalopods • squids and octopuses • internal mantel
~Invertebrate Phylum Annelida ~ • Segmented worms • Body divided into segments (sections) • Live in water or underground • have a nervous and circulatory system
~InvertebratePhylum Annelida ~ • Class Earthworms • eat soil and breakdown organic matter, wastes provide nutrients to soil
~InvertebratePhylum Annelida ~ • Class leeches • parasites that feed on blood of other animals
~Invertebrate Phylum Arthropoda ~ • Body divided into sections/segments • Exoskeleton • Jointed legs • well developed nervous system • largest group of organisms on earth
~Invertebrate Phylum Arthropoda ~ • 3 subphylums: • Classified into classes according to the number of legs, eyes and antennae they have.
~Invertebrate Phylum Arthropods ~ Subphylum Uniramia • Class Insecta • no antennae • 3 pairs of legs • 2 body regions - head, thorax & abdomen • grasshoppers, ants, butterflies, bees
~ Phylum Chordata ~ subphylumVertebrata 5 classes • Fish • Mammals • Reptiles • Amphibians • Birds
Fish • Are cold-blooded • Have gills and scales • Live in water • Have a Backbone
Reptiles: • Have scales • Live on land • Are cold-blooded • Usually lay eggs • Have a Backbone
These are Reptiles Crush!!!
