All rights reserved. The pericarp (Figure \(\PageIndex{2}\)), which is comprised of the exocarp, mesocarp, and endocarp, is derived from the ovary wall.
Interestingly, studies have shown that even half-eaten acorns can still sprout if the embryo inside is undamaged, meaning that squirrels unwittingly disperse more seeds than just those in their forgotten stores.
What are the advantages and disadvantages of each type of dispersal? But certain other seeds actually require digestion in order to sprout. Several freshwater plants, including the lotus, employ similar strategies and have long dormancies that allow them to wait until conditions are favorable to sprout. They eat the entire fruit and only the juicy part is digested by their system and the seed are excreted out in the form of their dropping, which forms into new plants.
These modes are typically inferred based The coconut palm tree goes by the Latin name Cocos nucifera. We use cookies to ensure that we give you the best experience on our website.

Accessory fruits (sometimes called false fruits) are not derived from the ovary, but from another part of the flower, such as the receptacle (Figure \(\PageIndex{4}\)) or the hypanthium (Figure \(\PageIndex{5}\)).
Dry fruits can be further classified into dehiscent fruits, which open at maturity, or indehiscent fruits, which do not open independently. Some plants have coevolved with animals in such a way that their seeds are collected and helpfully buried in a clever symbiosis. Coconuts are well known for their ability to float on water to reach land where they can germinate.
These tenacious structures typically feature hooks, barbs, spines, or even mucilage to attach to a passing animal. The thick floating fruits are impermeable to water and are filled with nutrients to keep the embryo alive for months at sea. Fruits promote the dispersal of their content of seeds in a variety of ways: All of the above mechanisms allow for seeds to be dispersed through space, much like an animals offspring can move to a new location. Seed dispersal. Fruits and seeds are dispersed by various means. The coconut trees general appearance is its main adaptation to the climatic changes of heat and heavy winds.
