flowering plants, the seeds develop from the ovules, which are then enclosed in _____ tissue to form a fruit to aid in dispersal. In addition, fruits can be monomerous (1-seeded) like a nut or an achene, or bear multiple seeds (like the follicle in a tulip, Tulipa). The seed coat is attached to the thin, dry ovary wall (husk) by a short stalk, so that the seed is easily freed from the husk, as in buckwheat. But we dont know the specifics.

Seeds disperse into new sites where they grow or germinate under favourable conditions.. The phenomenon where the "seeds" turn into green shoots all over the surface of a strawberry is called "vivipary." Vivipary occurs frequently in some plants, but only intermittently in others, like the strawberry.

Over time, the process of natural selection has ensured that those strawberry plants that produce the reddest and sweetest strawberries have genetic descendants. Fruits may be classified as simple, aggregate, multiple, or accessory, depending on their origin (Figure \(\PageIndex{11}\)). But that still doesn't answer the question, it just changes it a little.
