Chapter 11 Structure and Function of Invertebrates What major functions do animals’ bodies perform? On a walk through the park, you stop to look closely at the leaves of a plant. You see an insect laying eggs. The eggs are the result of sexual reproduction. The cells in each insect egg contain many genes. Where do these genes come from? Explain your answer.
Chapter 11 Structure and Function of Invertebrates Use Clues to Determine Meaning What a polyp is The animals called cnidarians have two different body plans. One form looks something like a vase. The vase-shaped body plan is called a polyp. A polypís mouth opens at the top and its tentacles spread out from around the mouth. Additional information about a polyp
Chapter 11 Structure and Function of Invertebrates Apply It! 1. In your own words, what is the meaning of polyp? Sample: A polyp is a vase-shaped cnidarian. 2. What sentence contains the definition of polyp? Sentence 3 3. What other clues help you understand the meaning of polyp? The last sentence tells me it has a mouth that opens at the top and is surrounded by spreading tentacles.

Chapter 11 Structure and Function of Invertebrates Characteristics of Worms Biologists classify worms into three major phyla—flatworms, roundworms, and segmented worms.
Chapter 11 Structure and Function of Invertebrates Life Cycle of a Dog Tapeworm This tapeworm is a parasite that lives in more that one host during its life cycle.
Chapter 11 Structure and Function of Invertebrates Roundworm Numbers Biologists counted all the roundworms living in a plot of soil. Then they calculated the percentage that lives in different depths of soil.
Chapter 11 Structure and Function of Invertebrates Roundworm Numbers Reading Graphs: Where in the soil was the largest percentage of roundworms found? In the first centimeter
