Angiosperm reproduction involves the production of seed(s) within a fruit. The biological definition of fruit is the part of the plant that bears the seed(s), so it includes any example of a plant that makes seeds. Those would include things like tomatoes, green beans, apples, oranges, watermelon, dandelions, oak trees, and corn. The method is a plant produces a flower, such as an apple tree blossoming in spring. The flower contains the reproductive parts of the plant. The pistil (female part) has a sticky top (called the stigma) and an ovary filled with eggs at its swollen base. Surrounding the pistil are stamens--long slender filaments with a powdery knob (called the anther) covered with pollen dust on the top (male part--has sperm). When pollen from anthers lands on the stigma the pollen will begin to grow a pollen tube down into the bottom of the pistil into the ovary where it can fertilize the egg(s). The fertilized ovary will begin to swell--the flower petals will fall off and the ovary becomes the fruit that contains the seeds. For example, an apple. For a fern, it reproduces by producing spores on the undersides of the fronds (the name for fern leaves). The spores are produced in tiny bumps called sori or fruitdots. Each sorus (singular for sori) is made of a bunch of little sacs called sporangia which contain several spores each. When they are mature they will burst open and spores will travel in the wind. If the spores land in a suitable environment, they may grow a new fern plant. An example is the boston fern--it is a common houseplant.
