What type of fleshy fruit is a blueberry




















The berries that are developed in citrus flowers have carries exceedingly oily surface layers over a pithy subtending layer. A specialized berry in citrus is referred as a hesperidium. Another example includes lemon, orange, lime and grapefruit. In these, the compound is a pistil forms of fruit and also have the individual "sections" are the ovaries of carpals that are fused into that one pistil. Other specialized berries develop from flowers with the inferior ovaries. These will, of course, have the accessory layers contributed by surrounding receptacle and other necessary tissues.

A very large group of well-known examples include watermelon, cucumber, squash and pumpkin. In these referred plants the specialized berry is known as pepo. In watermelon people love eating the true fruit.

For pumpkin, cucumber, and squash people generally prefer the accessory rind rather than the slimy actual fruit. Drupes - Almond, Plum, Peach The drupe is a type of fleshy fruit that has a stony inner layer surrounding normally a single seed. Dehiscent Dry Fruits: Pericarp splits open along definite seams. Legume: An elongate "bean pod" splitting along two seams; typical fruit of the third largest plant family, the legume family Leguminosae or Fabaceae.

The pod represents one folded modified leaf or carpel that is fused along the edges. Note: Some legume fruits are indehiscent, including the carob tree, mesquite and honey locust. In addition, some legume fruits are oblong, rounded, kidney-shaped reniform , or coiled spiral-shaped , such as sweet clover Melilotus alba and M. Some specialized legume fruits called loments break apart into indehiscent one-seeded joints. A good example of a loment is the very effective hitchhiker called stick-tights or beggar's-ticks Desmodium cuspidatum.

Achene: Very small, one-seeded fruit, usually produced in clusters. At maturity the pericarp is dry and free from the internal seed, except at the placental attachment. This is the typical fruit of the largest plant family, the sunflower family Compositae or Asteraceae. Examples of this type of fruit include the sunflower Helianthus , buttercup Ranunculus and sycamore Platanus.

In the sycamore, the globose fruiting heads are composed of tiny, one-seeded achenes interspersed with hairs some authors refer to these individual fruits as nutlets. Classified as a "glans" by Richard Spjut Classified as a "trymosum" by Richard Spjut Classified as a "diclesium" by Richard Spjut In true nuts, the hard, indehiscent layer surrounding the seed is the entire ovary wall or pericarp.

The outer husk of the walnut contains involucral tissue that is not part of the ovary wall pericarp. Cherries and peaches are drupes, as are avocados , a wild Mexican species of which is shown at the right, probably Persea shiedeana.

In the picture's lower, left corner a fruit has been cut lengthwise. Its greenish, edible flesh mesocarp is covered with a thin peel exocarp. The picture's topmost item is a cut-open fruit with the seed, revealing the woody endocarp. At the picture's far right, that's the seed itself.

Pomes are fleshy fruits formed from inferior ovaries having two or more carpels, the fleshy part being derived from the former flower's ovary wall pericarp , and a hypanthium explained below.

Apples and pears are the best known examples of pomes. At the right, a broken-open pear-tree flower shows stamens arising from a crown of green tissue encircling the ovary's top. The Pome The pome consists of tissue derived from the ovary and from the perianth. For this reason it is often called an accessory fruit. In the example apple the core is composed of modified tissue from the ovary wall while the pulp is composed of tissue from the base of the floral tube and receptacle.

The seeds were once, early in development, ovules containing fertilized eggs and endosperm. The pear is another pome type of fruit. Simple Fleshy Fruits. The Berry. Grapes and tomatoes are classified as berries because the ovary wall of the carpel becomes almost completely fleshy at maturity.

The Hesperidium.
