When the fruit ripens it gets detached from the stalk, the internal pressure is released and some of the contents, including the seeds, are literally ‘squirted’ out. And it's free for everyone. Examples of such seeds are tomato, pepper, cotton seeds etc. (iii) Seed dispersal helps the plants to grow in new places (or new habitats) for wider distribution. This pappus is of different appearance in different species and in many cases it is large and light enough to keep the cypsela fruit floating in air for a long time. Seed dispersal is sometimes split into autochory (when dispersal is attained using the plant's own means) and allochory (when obtained through external means). 468), Pandanus (Pandanaceae) and also of a few leguminous plants.

Some fruits, such as the dandelion, have hairy, weightless structures that are suited to dispersal by wind. A rather interesting type of wind dispersal is shown by certain weeds like Salsola kali tenuifolia which grow on sea coasts. This is important because if the seeds are not dispersed, many germinating seedlings will grow very close to the parent plant… These analyses demonstrate that TAGL1 plays an important role in regulating both fleshy fruit expansion and the ripening process that together are necessary to promote seed dispersal of fleshy fruit. 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!

In this case, as the fruits get ripened, it shoots out its seeds into the external environment. In these pods the seeds are arranged in four rows and the flat lens-shaped seeds have peculiar hood-like projections, called jaculators or retinacula, from their funicles which straighten out during dehiscence so that the four rows of seeds are ejected cross­wise in four different directions.
