Do all plants have to have flowers to reproduce?

Which came first, the flower or the bee? Flowering plants can't reproduce without insects to move the pollen around, bees and other insects need the nectar that flowers provide. (Sorry if this is a dupe, it didnt look like it posted the first time)

• Answer:

  G'day Avallach, Thank you for your question. The flower came well before the bee with the earliest fossil of a flowering plant being 125 million years old. Early flowers were pollinated by other insects primarily beetles. Flies, butterflies and other insects as well as birds such as hummingbirds pollinate flowering plants. The bees evolved from wasps. While bee fossils are rudimentary, the earliest bee fossils date back to the Eocene period of 55.8 to 33.9 million years ago. I have attached sources for your reference.
