  23. 28. ways that seeds spread :
  24. 29. Coconuts -seeds scattered by water.
  25. 30. animals help scatter seeds
  26. 31. carried by animals bur
  27. 32. asexual reproduction <ul><li>2 ways: runners & budding </li></ul><ul><li>only 1 parent (no sperm or egg cells) </li></ul><ul><li>offspring have same genes as parent </li></ul>
  28. 33. Spider plants are common houseplants that can reproduce by growing new plants on long stems called runners.
  29. 34. Duckweed is a tiny plant that floats on ponds and is food for ducks and other birds. It is one of the smallest flowering plants, but it reproduces mostly by a kind of asexual reproduction called budding. Little buds form on the plant and drop off to grow as separate plants.
