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 SIMILARITIES1 parent 2 parents Offspring genetically identical to parent Offspring NOT genetically identical to parents Uses mitosis Uses meiosis No gametes and fertilization Gametes and fertilization New individuals produced Genetic material passed on to offspring Parents Offspring Cell division Gametes and fertilization

3 AB C D E Answer the questions using the cell images shown below. 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 Telophase EADCB

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

5 A Amniotic fluid Umbilical cord C B 1.Identify the type of development occurring in this picture. 2.Identify the types of organisms that use this type of development. 3.Identify the labeled structures.

6 1.Identify the structures labeled. 2.Identify the process that occurs in structure E. 3.Describe the path of sperm throughout the male reproductive tract. 4.Describe the importance of structure F.

7 1.Identify the structures labeled. 2.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 1.Identify the type of development observed in the diagram. 2.Identify the types of organisms that use this type of development. 3.Identify the source of nutrition for the embryo. 4.Identify what cushions and protects the embryo. External development Aquatic and terrestrial Yolk Amniotic fluid

11 1.Identify the structure that produces estrogen and progesterone. 2.Where does a zygote develop? 3.Where is the egg fertilized? 4.Where does the placenta form? 5.Identify the process when an egg is released from an ovary. 6.Identify the process that occurs in the ovaries. B - ovary D - uterus A - oviduct D - uterus Ovulation Meiosis

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

15

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

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

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

19 5. Identify the two types of metamorphosis. Incomplete metamorphosis Complete metamorphosis

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

21

22

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

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

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

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

27

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

31 12. Identify 2 other names for larva. Grubs Maggots

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

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

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

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

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

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

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

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

43 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

44 1.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

45 1.Identify each labeled structure in the diagram. 2.Identify the structure where the fetus develops. 3. Identify the structure where meiosis occurs. 4.Identify the structure where fertilization occurs.

46 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.

47 1.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.

48 What is the primary function of this egg? 1.food supply for predators to preserve predator populations 2.adaptation to allow maximum freedom for parent birds 3.continuation of the species through reproduction 4.preservation of the exact genetic code of the parent birds

49 An adaptation for reproduction in most terrestrial organisms is (1) vegetative propagation (2) internal fertilization (3) regeneration (4) mitosis

50 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?

51 Which represents binary fission? Support your answer.

52 External fertilization occurs most often in 1.mammals and birds 2.reptiles and birds 3.amphibians and reptiles 4.fish and amphibians

53 1.Identify the process represented in the diagram. 2.Where does this occur? 3.Describe what happens to the chromosome number. 4.Compare the daughter cells to each other.

54 The blockages shown at A and B would most likely interfere with the ability to 1.transport gametes 2.produce mature gametes 3.eliminate waste products through the urethra 4.express secondary sex characteristics

55 avior/metamorphosis/fyi/

56 The process in which insect species change their body shape form and become adults is known as (1) mitosis (2) metamorphosis (3) meiosis (4) cleavage

57 Metamorphosis in which larva develop inside pupa is known as (1)incomplete metamorphosis (2) transitional metamorphosis (3) embryonic metamorphosis (4) complete metamorphosis

58 1.The part of the pistil which contains the pollen tube is the __________. 2.The transfer of pollen between the anther and the stigma in any flowering plant or plants is called _____. 3.In order to reach an ovule, a ______ must grow through the style. 4.The sex cells in a flowering plant are located in the ____. 5.The egg cell of a flowering plant develops in the _____.
