Our analysis on existing seed data reveals that water‐dispersed riparian plants have relatively large seeds and are thereby evolutionarily adapted to long‐distance dispersal. Furthermore, our results indicate that median dispersal distances are 0.02–1.8 km (99‐percentile <8.5 km) in lowland streams in summer.

Not only that, what is inside a seed?
Inside of the seed would be a tiny plant called the embryo. The two large parts of the seed are called the cotyledons. The cotyledons are stored food that the young plant will use while it is growing. Monocots are seeds that have only one cotyledon, such as the corn seed.
Still, how is Jacaranda dispersed? The jacaranda tree (Jacaranda mimosifolia) of northwestern Argentina. Like many other members of the Bignonia Family (Bignoniaceae), the papery, winged seeds flutter and spin as they are carried by the wind. ... When released from their seed capsules they flutter or spin through the air.
Other than that, how are mangrove seeds dispersed?
Rather than producing dormant resting seeds like most flowering plants, mangroves disperse propagules via water with varying degrees of vivipary or embryonic development while the propagule is attached to the parent tree. ... The white mangrove's dispersal period is the shortest at 5 days, which also includes germination.
How are hard fruits dispersed?
As fruits/seeds dispersed by wind are light and have wing-like structures or feather-like structures, they have a larger exposed surface area in contact with the air. ... Therefore, fruits/seeds dispersed by wind would be found far away from the parent plant in the direction of the wind.

Acacia comprises both indehiscent and dehiscent species. The pods of the former remain on the tree until browsed or knocked off by browsers or mechan- ical action such as wind. Dehiscent pods open on the tree, exposing seeds to physical forces such as wind or gravity which disperse seeds from their pod.
Violets, poisonous squirting cucumbers, and touch-me-nots or Impatiens capensis (not to be confused with these touch-me-nots) have an effective way of dispersing their seeds: They burst! The forceful ejection sends the seeds flying as far away as possible from the original plant.
Explosions Pea and bean plants also keep their seeds in a pod. When the seeds are ripe and the pod has dried, the pod bursts open and the peas and beans are scattered.
- Strawberries are the first fruit to ripen each spring. ...
- There are 200 seeds on an average strawberry. ...
- Despite their name, strawberries aren't technically berries—they're accessory fruits. ...
- The seeds can grow into new strawberry plants, but most instead reproduce through runners.
Bareroot strawberries can be planted anytime. But when you start strawberries from seed, you'll want to keep them indoors in the early spring to help them along until the last frost has passed. Simply press the seeds into a moist potting medium in seed starter trays, and allow several weeks for germination.
Well, a berry has seeds and pulp (properly called “pericarp”) that develop from the ovary of a flower. ... The pericarp of all fruit is actually subdivided into 3 layers. The exocarp is the skin of the fruit, and in berries it's often eaten (like in grapes) but not always (like in bananas).
Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. Some have a parachute-like structure to keep them afloat. Some fruits—for example, the dandelion—have hairy, weightless structures that are suited to dispersal by wind.
