Seeds Animals Don't Eat. Dispersal Mechanisms: Seeds can be dispersed long distances by wind because they move in updrafts. Note: If the fleshy part of the fruit is composed of something other than the ovary, it is an accessory fruit. 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. [clarification needed] Many cypselas (e.g. 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. However, mammals like you and I interpret capsaicin as spicy, perhaps painful, and are often deterred by it (though many exceptions apply among humans), while birds are immune to these effects. Another strategy for seed dispersal is to use animals to carry seeds to suitable The fertilized ovaries in the flower form separate, small, dry fruits.

Use characteristics of fruits to predict the dispersal agent for a plant's seeds. And then someone told me that apples are not true fruits either. ENVS 150 Exam 3 (Foret) Flashcards | Quizlet Dispersal may occur by a number of different means, including gravity (basically, a simple means of dispersal involving the seed falling and potentially rolling downslope a short distance), wind, water, animals, and ballistic dispersal (adaptations that launch seeds from the fruit). Dispersal agent carrying F. chiloensis to Chile and Hawaii. Samaras of Acer buergerianum are achenes with large wing-like structures. Fruits can be dry or fleshy.
