Presentation transcript:

Wake-up 1.Write down three characteristics of worms. 2.Write down two different types of worms.

Worms

Flatworms

Skeletal system: Hydrostatic

Digestive system: Two way

*

Respiratory system: Diffusion

Nervous system: Nerve Cell Ganglia (control center) with 2 nerve cords Eyespots

Reproductive system: Hermaphrodite; both sexes present for internal fertilization

Reproductive system: Fragmentation

Planarian

Marine Flatworms

Tapeworm

*

*

Liver Fluke

Nematoda - Roundworms

Skeletal system: Hydrostatic

Digestive system: One way

Respiratory system: Diffusion

Nervous system: Nerve Cell Ganglia (control center) with 2 nerve cords Eyespots

Reproductive system: Internal fertilization

Hookworms

*

Annelida – Segmented Worms

Symmetry Bilateral: Can be split evenly into two halves

Skeletal Hydrostatic skeleton: “Water” skeleton Water

Digestion One-way: Food moves into mouth and out an anus

Circulatory Closed system: Blood is within vessels; have 5 “hearts”

Respiratory Diffusion: absorb oxygen through the skin; skin has to be moist O2O2 O2O2

Nervous Nerve cell: Control center; nerve cord

Reproduction Hermaphrodite –Both sexes present; both worms fertilize each other eggs

Special Characteristics Has small spines called SETAE on their outer most layer; helps anchor them to soil grains.

Example: Earthworm

Niche: Recycles organic matter; creates healthy soil

Example: Leech
