Review Plants-8

Pine trees do not have flowers. What structure do they have that servers the same purpose?

  1. Needles

    No. Pine needles are a kind of leaf. They are not used for reproduction.
  2. Cones

    Yes! Pine cones produce pollen and seeds, just as flowers do in flowering plants.
  3. Fruit

    No. Fruit are used for dispersing seeds, not for pollination.
  4. Buds

    No. Pine tree buds produce needles. They are not involved in reproduction.
