4	"Leaves" Leaves Stems Flowers Dead roots Plants
5	"There are 9,000 species of..." There are 9,000 species of segmented worms. Segmented worms do not have eyes, but they can tell between light and dark because of cells in the front part of their body. Segmented worms have five hearts. All of the hearts pump blood through their blood vessels just like our one heart.
6	"Annelids help the environment by" Annelids help the environment by: Recycling nutrients, minerals and other substances into the soil. Keeping the soil rich Removing rotten or rotting matter from the earth’s surface into the soil Opening the soil helps sunlight reach microscopic plants
7	"Worms have both male and..." Worms have both male and female parts, however they have to mate with another of its kind. Each worm then passes sperm, then joins with female eggs. Each worm lays its eggs in a cocoon that end up hatching into tiny baby worms.
8	"The ventral nerve cord ,..." The ventral nerve cord ,along the base of the body, carries signals to control the body parts, especially the muscles.
9	"-" - Segmented worms have five hearts. All of the hearts pump blood through their blood vessels just like our one heart.
10	"Hydrostatic skeleton is way to..." Hydrostatic skeleton is way to support a worms shape and structure through water pressure. This allows them to stretch and return to their original shape.
11	"A long gut tube runs..." A long gut tube runs through the worms body in the specialized regions. The pharynx takes in the food, the crop stores it, gizzard grinds it, and the long intestine digests the food.
12	"Circular:" Circular: The annelid body wall generally comprises an outer layer of circular muscle fibres Important for burrowing forms When the circular muscles that surround each segment contract, the segment becomes thinner and longer. Longitudinal: The annelid body wall generally comprises an inner layer of longitudinal muscle fibres Present as four distinct bands When the longitudinal muscles that extend from one end of the segment to the other contract, the segment becomes shorter but thicker.
13	"Because muscles can only contract..." Because muscles can only contract and cannot lengthen, other muscles are used to lengthen them. In annelids, when circular muscles contract to lengthen the segment, the longitudinal muscles are lengthened. When the longitudinal muscles contract to make the segment shorter and thicker, the circular muscles become lengthened.

15	"Mostly freshwater and terrestrial worms" Mostly freshwater and terrestrial worms This class is commonly thought of as “earthworms” Second largest group of annelida “Oligo” means few Animals with few chaetae, or few bristles
16	"Mostly marine worms" Mostly marine worms More than 8,000 are Polychaetes Can be found floating free near the surface or burrowing in the mud and sand The name Polychaete, in fact, means "many bristles"
17	"Examples:" Examples: Lugworms Clam worms Bristle worms Fire worms Feather duster worms Palolo worms Sea mice
18	"In northeastern America there are..." In northeastern America there are about 42 different species Most are found in fresh and marine water but some are also found in tropical regions An example of a Hirudinea would be a leech
19	"Hermaphrodite:" Hermaphrodite: an animal that has both male and female organs Segments: move in an accordion like fashion to help move the worm Setae: movable bristles along the worms body, group the ground and keep worm from slipping
