How Do Organisms Reproduce? Directions: Make a book about reproduction. Follow the steps below to make the book. Use the index and table of contents of the text book to research the information about reproduction. Front Cover: How Do Organisms Reproduce? (1pt) 1. Write the title “How Do Organisms Reproduce?” in the center of the page. 2. Write the name of the author on bottom right hand corner “By: Your Name” Page 1: Types of Reproduction (9pts) 3. Write the title “Types of Reproduction” at the top of the page. 4. Define Reproduction in a sentence. 5. What are the two types of reproduction? (Write in a sentence) 6. Make a Double Bubble Map to comparing the two types of reproduction. Use the following phrases in your Map. Involves 2 parents Produces fewer offspring Involves 1 parent Reproduces quickly Genetically identical to the parent Reproduces slowly Genetically different Organisms: Hydra, to the parent Yeast, Bacteria, Some Plants Produces offspring Organisms: Mammals, Passes traits (genes) Birds, Flowering to a new generation Plants Produces many Uses Mitosis offspring Uses Meiosis Page 2: Asexual Reproduction (5pts) 7. Write the title “Asexual Reproduction” at the top of the page. 8. Define Asexual Reproduction in a sentence. 9. Cut out the pictures and captions on Appendix A. 10. Match the picture to the captions and glue them into the book. Page 3: Sexual Reproduction (4pts) 11. Write the title “Sexual Reproduction” 12. Define Sexual Reproduction in a sentence. 13. List six organisms the reproduce sexually and one fact about their reproduction. (one reptile, one bird, one fish, one amphibian, one mammal, one plant) Page 4: Reproduction in Mammals (6pts) 14. Use the information in Appendix B to develop a table that identifies and explains reproduction in mammals. 15. Cut and paste the images and words to arrange in a table in the book. Page 5: Reproduction in Angiosperms (Flowering Plants) (10pts) 16. Label the plant diagram in Appendix C by using colors to identify the parts. 17. Use the word bank to fill in the blanks of the diagram caption. 18. Cut and paste the diagram and caption into the book. Appendix A Bulb Bacteria Hydra Binary Fission is the separation of parent into two individuals. First, the DNA is copied and then the cell divides making a new offspring. The offspring produced is the same size as the parent. Budding is when new individuals are grown off of the parent then eventually break from the parent and become an independent organism. The offspring produced is smaller than the parent. Some plants use non reproductive parts, such as stems, roots, and leaves, to reproduce by growing new plants from the planted parts. The reproduction of plants from these parts is called Vegetative (Plant) Propagation. Appendix B Reproductive Strategies Definition Monotreme Young are born underdeveloped and continue to develop in the pouch of the mother Organisms Special Characteristics Young hatch undeveloped and drink mothers milk until developed. Cows, Humans Marsupials Develop fully in the uterus and receive nutrient from placenta Young is most developed at birth. Platypus, Echina Placental Mammals Young attaches to nipples in the pouch to gain nutrients Reproduce by laying eggs with leathery shells. Kangaroo, Koala Appendix C Basic Angiosperm Reproduction Matching: 1. ______ Petals 2. ______ Ovule 3. ______ Pollen (grain) 4. ______ Ovary 5. ______ Anther A. Female reproductive structure, produces ovules B. Female sex cells (gamete) C. Attracts pollinators D. Male reproductive structure, a pollen producing sac E. Male sex cells (gamete) The flower reproduces when pollination occurs. The ___________________ attract pollinators to help reproduction occur. The wind or animals transport the ______________ from the _____________________ to the style of the pistil. The pollen then travels down the stigma to reach the ovule in the ___________. When the pollen (male sex cell) and ____________(female sex cell) join together in fertilization, then a seed is produced to make a new offspring.
