  1. Reproduction Review

  2. What is the name of the process represented in the diagram? • 2. What type of cell division is involved? • 3. Identify some organisms that use this process. • 4. What type is reproduction is represented? • 5. Describe the offspring of this process. Binary fission mitosis ameba, paramecia, bacteria asexual offspring genetically identical to parent cell.

  3. What is the name of the process represented in the diagram? • 2. What type of cell division is involved? • 3. Identify some organisms that use this process. • 4. What type is reproduction is represented? • 5. Describe the offspring of this process. Budding mitosis Yeast, hydra asexual offspring genetically identical to parent cell.

  4. Identify each type of asexual reproduction below. Binary fission Budding Regeneration Vegetative propagation Vegetative propagation Sporulation

  5. Asexual repro uses ONE PARENT while sexual repro uses TWO PARENTS. What are the differences between asexual and sexual reproduction? • Asexual repro uses MITOSIS while sexual repro uses MEIOSIS. • Asexual repro produces offspring that are genetically identical to the parent. Sexual repro produces offspring that are similar but NOT genetically identical to the parents. • Sexual repro involves the FERTILIZATION while asexual repro DOES NOT REQUIRE FERTILIZATION .

  6. Mitosis produces 2 daughter cells while meiosis produces 4 daughter cells. What are the differences between mitosis and meiosis? • Mitosis produces daughter cells with the same # of chromosomes as the parent cell while meiosis produces daughter cells with the half the # of chromosomes as the parent cell. • Mitosis is used for asexual reproduction while meiosis is used for sexual reproduction. • Mitosis is used to replicate somatic cells while meiosis produces gametes (sex cells).

  7. Identify processes A and B. Support your answer. A – Meiosis 4 daughter cells B – Mitosis 2 daughter cells 2. Identify the type of reproduction each process is involved in. A – Sexual repro B – Asexual repro B A

  8. 3. Identify the type of cells produced in each process. A – Gametes B – Somatic cells 4. Identify what occurs to the # of chromosomes in each process. A – Chromosome # splits in half B – Chromosome # stays the same B A

  9. What process is represented in the diagram? • Where does this process occur? • 3. How many chromosomes are found in these human gametes? meiosis testes 23

  10. C D E B A • Identify the process represented in the diagram above. Support your answer. • 2. If the first cell is made up of 32 chromosomes, how many chromosomes are found in the daughter cells? • 3. Identify the types of cells produced by this process. • 4. Identify the type of reproduction involved. Mitosis – 2 daughter cells 32 Somatic cells Asexual reproduction

  11. B C A D E Development of an embryo • What does this process represent? • What processes do B and C represent? • What does structure D represent • What does structure E represent? • Which structure forms after the blastula? • Which process occurs after the gastrula? cleavage morula blastula gastrula differentiation

  12. zygote • What is structure A? How was it produced? • 2. Which structures represent cleavage? • 3. What is structure E? • 4. What is structure F? • 5. What process occurs after structure F is formed? • fertilization B, C, D blastula gastrula differentiation

  13. The development of different organs and tissues from the embryonic germ layers is called (1.) ovulation  (2.) menstruation  (3.) cleavage  (4.) differentiation

  14. What kind of fertilization is taking place above? Explain why so many eggs are released during this process? What kind of organisms use this process? External fertilization To increase the chance of fertilization Aquatic organisms

  15. Identify the structures labeled. 1 - cervix 2 – umbilical cord 3 - placenta 4 - oviduct 5 – amniotic fluid

  16. 4 - oviduct • Where did fertilization take place? • Where does the exchange of oxygen, nutrients and wastes occur between mother and fetus occur? • What protects the fetus? 3 - placenta 5 – amniotic fluid

  17. stigma anther H petal style G filament ovary F sepal E ovule

  18. H G • What is the name of the female reproductive organ? • What is the name of the male reproductive organ? F E Pistil Stamen

  19. H G • Which structures make up the pistil? • Which structures make up the stamen? F E H, G, F A, C

  20. anther Ovary Eggs are located in the ovules Petals Pollen has to stuck to the stigma. • Which structure produces the male gametes? 2. Which structure produces the female gametes? 3. Which structures attract pollinators? 4. In order for a flower to be pollinated, what does the pollen attach to?

  21. What does structure X represent? • What travels down structure X? Where will it go? Pollen tube • Sperm nuclei in pollen • Sperm nuclei must enter ovules

  22. What will the ovules eventually develop into once eggs are fertilized? • 2.What will the ovary eventually develop into? seeds fruit

  23. Identify all labeled structures in the flower diagram. seed coat D embryo A embryo B C cotyledon

  24. Identify the process in the diagram on the left. Metamorphosis

  25. Cells such as nerve cells and muscle cells are known as • gametes • sex cells • somatic cells • differentiated cells

  26. Which statement is true about sexual reproduction? • It produces offspring with half the number of chromosomes as the parent. • It involves sex cells joining together. • It produces offspring that are genetically identical to the parents.

  27. The result of meiosis are daughter cells that have • half the number of chromosomes • a quarter of the number of chromosomes • double the number of chromosomes • the same number of chromosomes

  28. The number of chromosomes found in human gametes is • 46 (2) 92 (3) 23

  29. The type of asexual reproduction in which involves the production of single cells by mitosis that are released into the environment is called • regeneration • binary fission • sporulation • vegetative propagation

  30. The type of asexual reproduction in which one cell divides into to two cells that are of equal size is called • regeneration • binary fission • sporulation • vegetative propagation

  31. Asexual reproduction in plants is known as • regeneration • vegetative propagation • binary fission • sporulation
