EVERYDAY SCIENCE

Detailed explanation-1: -Each of the individual ‘seeds’ of the sunflowers are actually entire fruits called achenes with a single seed present inside each one. Sunflower seeds and an incredibly important source of food for wildlife, especially when it gets cooler outside and animal/insect protein is less available.

Detailed explanation-2: -The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue.

Detailed explanation-3: -An achene is a one-seeded, dry, indehiscent fruit with seed attached to the pericarp at one point only, such as the unit fruits of sunflowers. An anthocarp or diclesium is an achene or nut, surrounded by the persistent and accrescent perianth, as in Pontederia or the Nyctaginaceae.

Detailed explanation-4: -Fleshy fruits include the berry, drupe, pome, pepo, and hesperidium. Grapes and tomatoes are classified as berries because the ovary wall of the carpel becomes almost completely fleshy at maturity.
