It looks like two seeds joined together each with a wing attached to the outside. When the seed is released from the tree it descends like a helicopter, and given a breeze can fly a fair distance.
The seed-dispersal mechanism would be wind, because it has a wing structure.
Seed germination typically takes place in the soil. The seed absorbs water from the soil, which triggers the germination process by initiating metabolic functions that allow the seedling to sprout and grow.
It is dispersed by wind because it has wing-like structures.
The wing of a bat is most similar to a human arm in terms of its bone structure, as both have similar bone segments (humerus, radius, and ulna) despite being adapted for different functions.
The hilum is some type of embryonic scar on the seed that lets the seed dry out.
Both help it to fly.

The ovule of an angiosperm, which will eventually become a seed, is surrounded by integuments. They are layers of protective sporophytic tissue that eventually develop into the seed coat.

Seed germination typically takes place in the soil. The seed absorbs water from the soil, which triggers the germination process by initiating metabolic functions that allow the seedling to sprout and grow.
The wing extension of a pine seed helps in wind dispersal, enabling the seed to be carried away from the parent tree and increase the chances of successful germination in a new location. The wing also aids in aerodynamic lift, allowing the seed to travel further distances before settling on the ground.
It is dispersed by wind because it has wing-like structures.
A samara is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall.
