Various edible fruits arranged at a stall at the Municipal Market of São Paulo Fresh fruit mix of blackberries, strawberries, and raspberries. In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering (see Fruit anatomy).
Fruit anatomy is the plant anatomy of the internal structure of fruit. [ 6 ] [ 7 ] In berries and drupes , the pericarp forms the edible tissue around the seeds. In other fruits such as citrus and stone fruits ( Prunus ) only some layers of the pericarp are eaten.
Fruit type has been considered to be a useful character in classification and in understanding the phylogeny of plants. [32] The evolution of fruits with a berry-like pericarp has been studied in a wide range of flowering plant families. Repeated transitions between fleshy and dry pericarps have been demonstrated regularly.
A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm.Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds that do not have a surrounding fruit, this meaning that juniper and yew "berries" are not fruits, but modified cones.
Its function is to ensure fertilization of the ovule and development of fruit containing seeds. [55] It may arise terminally on a shoot or from the axil of a leaf. [56] The flower-bearing part of the plant is usually sharply distinguished from the leaf-bearing part, and forms a branch-system called an inflorescence. [37]
In most plants, stems are located above the soil surface, but some plants have underground stems. Stems have several main functions: [3] Support for and the elevation of leaves, flowers, and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.
The dark horizontal lines on silver birch bark are the lenticels. [1]A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of gymnosperms and dicotyledonous flowering plants. [2]
A bur (also spelled burr) [1] is a seed or dry fruit or infructescence that has hooks or teeth. The main function of the bur is to spread the seeds of the bur plant, often through epizoochory. The hooks of the bur are used to latch onto fur or fabric, enabling the bur – which contain seeds – to be transported to another location for ...
