Why do some plants have fruits and seeds but they don't have flowers?

Some plants actually have fruits which have seeds in them but they actually don't have flowers... Why is that so?

FlowersBirthday FlowersSympathy FlowersNo examples of this type of scenario come to mind immediately, and I think that I know why. What you consider to be flowers and what the plant's flowering reproductive body actually is may not always be the same thing. All fruiting plants have flowers, but some may be so small that they are imperceptible or unrecognizable to the human eye (like the flowers that make up the bushy part of a cauliflower). If the flowers are too small to be pollinated by insects, then they may be pollinated by the wind, or in some cases, pollinated by the plant itself.
Reply:Plant that have "Flowers" are in a group Known as the angiosperms. The flowers are a way to reproduce. EX. Flowers attract bees that will spread the pollen. Not all plants require "flowers" to reproduce. Fruit is basically the ripened ovary and associated parts. Some plant don't produce seed, they reproduce asexually or self propagate. If you pick up any plant bio or botany book, you will find there is a lot of detail to the answer of your question.acting resources
