Inside the pit 1–2 mm (0.039–0.079 in) thick is a thin lining covering a single seed, 4–7 cm (1.6–2.8 in) long. Mangoes have recalcitrant seeds which do not survive freezing and drying. [14] Mango trees grow readily from seeds, with germination success highest when seeds are obtained from mature fruits. [4]
Apricot kernels Apricot stones (kernels are inside) An apricot kernel is the apricot seed located within the fruit endocarp, which forms a hard shell around the seed called the pyrena (stone or pit).

In contrast, rhubarb is often called a fruit when used in making pies, but the edible produce of rhubarb is actually the leaf stalk or petiole of the plant. [6] Edible gymnosperm seeds are often given fruit names, e.g., ginkgo nuts and pine nuts. Botanically, a cereal grain, such as corn, rice, or wheat is a kind of fruit (termed a caryopsis ...
Nuts, on the other hand, do not release seeds as they are a compound ovary containing both a single seed and the fruit. Nuts also do not split. In the Brazil nut, a lid on the capsule opens, but is too small to release the dozen or so seeds (the actual "Brazil nut" of commerce) within. These germinate inside the capsule after it falls to the ...

An endosperm is formed after the two sperm nuclei inside a pollen grain reach the interior of a female gametophyte or megagametophyte, also called the embryonic sac.One sperm nucleus fertilizes the egg cell, forming a zygote, while the other sperm nucleus usually fuses with the binucleate central cell, forming a primary endosperm cell (its nucleus is often called the triple fusion nucleus).
