  1. Topic: Reproduction Aim: Describe the developmental patterns of insects. Do Now: Venn Diagram for Asexual and Sexual Reproduction – Work with your 12 o’clock partner. HW: Finish reading notes

  2. ASEXUAL SEXUAL 2 parents 1 parent SIMILARITIES Offspring NOT genetically identical to parents New individuals produced Offspring genetically identical to parent Uses mitosis Uses meiosis Genetic material passed on to offspring No gametes and fertilization Gametes and fertilization • Parents • Offspring • Cell division • Gametes and fertilization

  3. Answer the questions using the cell images shown below. D C E A B 1. What type of cell is shown in the pictures above? 2. Which cell is in the first phase of cell division? 3. Which cell is in anaphase? 4. What stage is shown in cell A? 5. Which stage is shown in cell B? 6. List the cells in the order they occur in cell division. Plant cell E C Prophase E A D C B Telophase

  4. Identify the type of asexual reproduction and support your answer. Vegetative propagation Budding Regeneration Vegetative propagation

  5. Identify the type of development occurring in this picture. • Identify the types of organisms that use this type of development. • Identify the labeled structures. A B Amniotic fluid C Umbilical cord

  6. Identify the structures labeled. Identify the process that occurs in structure E. Describe the path of sperm throughout the male reproductive tract. Describe the importance of structure F.

  7. Identify the structures labeled. Identify the process that occurs in structure E. Meiosis A – urinary bladder B - urethra C - penis D – vas deferens E - testes F - scrotum

  8. 3. Describe the path of sperm throughout the male reproductive tract. Testes  Vas deferens  Urethra 4. Describe the importance of structure F. The scrotum keeps the testes 2° to 4° cooler than the rest of the body. The cooler temperature is needed for optimum sperm production.

  9. Topic: Reproduction Aim: Describe the developmental patterns of insects. Do Now: Sit next to your 3 o’clock partner to work on reproduction review questions. HW: Seeds Close Reading ISN

  10. Identify the type of development observed in the diagram. • Identify the types of organisms that use this type of development. • Identify the source of nutrition for the embryo. • Identify what cushions and protects the embryo. External development Aquatic and terrestrial Yolk Amniotic fluid

  11. Identify the structure that produces estrogen and progesterone. • Where does a zygote develop? • Where is the egg fertilized? • Where does the placenta form? • Identify the process when an egg is released from an ovary. • Identify the process that occurs in the ovaries. B - ovary D - uterus A - oviduct D - uterus Ovulation Meiosis

  12. Molting 1. Identify the process in which insects shed their skin in order to grow.

  13. Under the existing exoskelelton 2. Where is the new exoskeleton produced?

  14. When insect reaches its adult stage 3. When does molting stop?

  15. Metamorphosis 4. Identify the process in which the body structure of an insect changes.

  16. Incomplete metamorphosis • Complete metamorphosis 5. Identify the two types of metamorphosis.

  17. Egg  nymph  adult 6. List the stages of incomplete metamorphosis.

  18. A miniature adult without wings 7. Describe what a nymph resembles.

  19. Each molt produces a larger, more mature nymph 8. What occurs before a nymph develops into an adult?

  20. Grasshoppers • Roaches • True bugs • Dragonflies • Praying mantises 9. Identify 5 insects that develop that have incomplete metamorphosis.

  21. Egg  larva  pupa  adult 10. List the stages of complete metamorphosis.

  22. Worms • Do not look like adults 11. Describe what larva resembles.

  23. Grubs • Maggots 12. Identify 2 other names for larva.

  24. They have 6 legs and simple eyes. 13. Why are larva classified as insects?

  25. Eat, grow and store fat 14. What do larva do during their lifetime?

  26. Molts one last time 15. How does a larva develop into a pupa?

  27. Chrysalis or cocoon 16. Identify the structure that encases the pupa.

  28. Internal structures of larva melt down and are reassembled into new structures. 17. Describe what occurs to the pupa while encased in that structure.

  29. Wings 18. Identify an example of structures that could develop inside the chrysalis.

  30. Pupa splits and final molt reveals the adult 19. How does the pupa develop into an adult?

  31. Fly, beetle, mosquito, butterfly, moth 20. Identify 5 insects that develop that have complete metamorphosis.

  32. 1. Identify structure X. 2. An obstruction in X would directly interfere with the (1) transfer of sperm to a female(2) production of sperm(3) production of urine(4) transfer of urine to the external environment 3. Identify structure A. 4. Identify the two substances produced by structure A. 5. Identify the process occurs in structure A. A

  33. Which the structure in which internal fertilization usually occurs? • (1.) allantois (2.) oviduct (3.) gonad (4.) uterus • 2. In which structure is a developing embryo implanted? • (1.) oviduct (2.) uterus • (3.) ovary (4.) vagina • 3. Which structure makes nutrients and oxygen directly available to the embryo? • (1.) uterus (2.) oviduct • (3.) placenta (4.) ovary

  34. Identify each labeled structure in the diagram. • Identify the structure where the fetus develops. • Identify the structure where meiosis occurs. • Identify the structure where fertilization occurs.

  35. 1. Which process is represented by the arrows in the diagram? (1) meiosis           (3) mitosis(2) fertilization      (4) evolution 2. Identify another name for this process. 3. Describe what occurs to the cells produced in this process. 3. Identify the result of this process.

  36. Identify the type of fertilization and development used to produce this egg. • 2. Identify the source of food for this embryo. • 3. Identify the structure that protects this embryo.

  37. What is the primary function of this egg? food supply for predators to preserve predator populations adaptation to allow maximum freedom for parent birds continuation of the species through reproduction preservation of the exact genetic code of the parent birds

  38. An adaptation for reproduction in most terrestrial organisms is • vegetative propagation • internal fertilization • regeneration • mitosis

  39. The diagram below represents chromosomes in a zygote. Which diagrams best illustrate the daughter cells that result from normal MITOTIC cell division of this zygote?
