The strawberry is a type of accessory fruit: its red fleshy part is actually the receptacle (which, if you recall, is actually the thickened part of a stem), while the structures embedded on its surface are actually tiny fruits, each bearing a single seed! The sperm cells remain inside the tube cell as the pollen tube goes through an opening in the ovule called a micropyle. Gymnosperm seeds are exposed while angiosperms seeds are enclosed in fruit. Angiosperms are commonly known as flowering plants that can be clearly distinguished from gymnosperms by certain derived characteristics. Examples of angiosperms range from dandelions and grasses to beans and fruits. These two fertilization events are collectively referred to as double fertilization. The entire whorl of sepals is referred to as the calyx. One type of cone is the small pollen cone, which produces microspores that subsequently develop into pollen grains. gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovuleunlike angiosperms, or flowering plants, whose seeds are enclosed by . Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores. Angiosperms have companion cells and xylem vessels in them, but these features are only present in Gnetales, a particular class of gymnosperms.
