Fruit, fruit, matured ovary of the pistil of a flower, containing the seed. In Juglans regia (English walnut) the fruit is a nut which develops from bicarpellary syncarpous, inferior and one-chambered ovary with one basal ovule. Share Your PPT File. This type of fruit is characteristic of Apiaceae (Umbelliferae) family, e.g., coriander, fennel, carrot, cumin, etc. Here a number of small drupelets develop from separate carpels of a flower and they are grouped together on a fleshy thalamus. It is the protective layer and may be thin or smooth or thin and papery. The groupings are not evolutionarily relevant, since many diverse plant taxa may be in the same group, but reflect how the flower organs are arranged and how the fruits develop. In orange and banana it is thread like. Pineapple2. The inner walls of the endocarp give rise to numerous juicy outgrowths which makes the edible part of the fruit, e.g., orange, lemon, etc. Ananas sativus (Pineapple). A collection of simple fruitlets makes an aggregate fruit. A fruit consists of two main parts - the seeds and the pericarp or fruit wall. The seed is large with convoluted cotyledons, which make the edible part of the nut. Just beneath the epicarp, the mesocarp is found. Here the ovules do not mature into seeds and therefore, the carpels develop into small nutlets that are seedless. The rachis and all the floral parts of the female inflorescence fuse together forming composite fruit. The inflorescence axis and the flowers all become fleshy. These fruits are dry and one-seeded. The fruit of gramineae is. It dehisces from below upwards by both the sutures Here the ovary is one-chambered at first, but later on it becomes two-chambered because of the development of a flase septum, the replum, which extends from one placenta to another.

An aggregate fruit, therefore consists of a collection of simple fruits as in Polyalthia. In the centre of the fruit, there is a club-shaped, thick, fleshy central axis, which is the inflorescence axis. The inflorescence axis produces a tuft of vegetative leaves, which forms a crown at the top.
