Achene Definition
Achene is a small, dry, one-seeded fruit. It is the simplest type of fruit and is composed of a single ovary wall. The ovary wall is fused to the placenta, which means the seed is not attached to the fruit wall.
About Achene
- An achene is a small, dry, one-seeded fruit that does not split open at maturity. It is typically produced by plants in the Asteraceae family.
- Achene is a small, dry fruit that is typically one-seeded. It is derived from the word “achene,” which is a diminutive of the Greek word “akon,” meaning “kernel.” Achene fruits are found in a variety of different plant families, including the rose family, the sunflower family, and the aster family. They are typically small, hard, and dry, and they often have a hard, smooth shell. The seed within the achene is often small and difficult to see.
Examples of Achene
Achene fruits are dry and small, with a single seed that is not enclosed in a fruit wall. The seed is attached to the fruit wall by a stalk, called a funicle. Examples of plants that produce achene fruits include sunflowers, dandelions, and thistles.
Variations of Achene
Achene fruits are dry and small, with a single seed that is attached to the fruit wall by a stalk. There are many variations of the achene fruit type. Some examples include the raspberry, blackberry, and strawberry. These fruits are all aggregate fruits, meaning that they are made up of many small fruits that are all attached to one another. The individual fruits that make up the aggregate are called drupes.
Bur-oak Acorns
Bur-oak acorns are one of the larger types of acorns, and they have a very tough shell. The acorns are also very bitter, which means that they are not usually eaten by animals. However, bur-oak acorns are a valuable food source for people, because they can be ground into flour.
What Does a Seed Contain?
A seed contains an embryonic plant and food reserves. The embryonic plant will grow into a new plant if the seed is planted in soil and watered. The food reserves provide the energy the embryonic plant needs to grow.
