achenes

the sunflower head was covered in numerous achenes.

these tiny achenes are the seeds of the sunflower.

dispersal of achenes relies on wind and animals.

the plant produces hundreds of small, dark achenes.

achenes are a type of dry, single-seeded fruit.

we collected the achenes to propagate the species.

the achenes are easily dispersed by birds.

achenes often have structures to aid dispersal.

the yield of achenes varied with the weather.

achenes are a key component of sunflower oil production.

we analyzed the achenes for oil content.
