  1. 2. fission Form of asexual reproduction
  2. 4. Attached to C on DNA
  3. 6. Plant structures called grains that carry sperm in a protective case to the ovules
  4. 7. Reproductive cells that grow into new individuals by mitosis
  5. 10. first stage of mitosis
  6. 11. Attached to A on DNA
  7. 12. an identical genetic copy of organism's parent
  8. 13. hormone released by pituitary gland
  9. 15. chromatid Joined together by centromere and replicates during interphase
  10. 21. Form of asexual reproduction in which each fragmentation develops into a clone of its parent
  11. 22. The final stage of the cell cycle, which separates the two nuclei and cell contents into two daughter cells
  12. 23. carries sperm from testes to ductus deferns
  13. 25. fertilization Fertilization in which sperm are deposited inside the female's body where they meet egg cells
  14. 27. reproduction Special cells dicide repeatedly to form structures that will develop into a plant identical to its parentn usually in plant stems and roots
  15. 28. thrid stage of mitosis where chromosomes split apart
  16. 30. The new dipliod cell formed by process of fertilization which receives half its chromosomes from its female parent and half from its male parent
  17. 31. chromosomes A pair of matching chromosomes
  18. 33. reproduction Reproducing using two parent
  19. 34. cycle Stages in a cell's life repeated
Down
  1. 1. Polymeric molecule
  2. 2. Form of asexual reproduction which may undergo mitosis and cell division can develop into an identical organism
  3. 3. Attached to T on DNA
  4. 4. Specialized cell neccessary for reproduction;in animals,male and female gametes are called egg cells
  5. 5. deferens A tiny muscular tube in the male reproductive system that carries sperm from the epididymis to the ejaculatory duct
  6. 8. fertilization Fertilization in which sperm cell and egg cell unite outside of bodies of parents
  7. 9. Transfer of male gametes in pollen from the male reproductive part of a plant to the female reproductive part of plant
  8. 13. egg cell is penetrated by sperm and haplois genetic information of both male and female combines
  9. 14. Attached to G on DNA
  10. 16. second stage of mitosis where chromosomes line up in the middle
  11. 17. Final stage of cell cycle which seperates two nuclei and cell contents to two daughter cell
  12. 18. One of the nucleobases in RNA
  13. 19. A steroid hormone from the androgen group and is found in mammals, reptiles, birds, and other vertebrates
  14. 20. Longest stage in cell cycle
  15. 24. cell Can develop into any kind of cell
  16. 26. Sperm and testerone are produced and form in male reproductive system
  17. 29. reproduction Reproducing using one parent
  18. 32. Process which gametes arrive in the same place at the same time
  19. 33. fibres Tiny tube like structures made by protein to help chromosomes pull apart
