Fennel, perennial herb of the carrot family grown for its aromatic shoots, leaves, and seeds. Native to southern europe and asia minor, fennel is cultivated in temperate regions worldwide. All parts of the plant are used in flavoring, and the bulblike stem base of the florence fennel variety is used as a vegetable.
Seed feature is one of the certain important characters used in the plant taxonomy. It has been known that the seed shape and the size are key to species also.
On some seeds, you can see the scar, or hilum, that was left behind when the seed became detached from the mother plant (similar to a human belly button). Hilum are most visible on bean seeds, where the scars as known as eyes — as in black-eyed peas. Others are less noticeable and look like little nubs or dents on the seed coat.
Among seed coat macromorphological characters used were seed dimensions, seed weight and testa color, while those of the hilum were lens and macula.

Some plants, such as conifers, have leaves that are shaped like needles or scales. Leaf shape is adapted to best suit the plant's habitat and maximize photosynthesis.
Heterogenous genus, portulaca, due to the variability of the seed characters in the genus. Summary in the family portulacaceae, seed morphology and anatomy have partitioned its members into two groups: those in which the seeds are pyriform with wings and trichomes in which the embryo is almost parallel to the endosperm and those.

There are three basic parts of a seed in the angiosperms: (a) an embryo, (b) a food storage or nutritive tissue, and (c) seed covering. Seed anatomy is specifically designed as a self-contained unit which, under the right conditions, will become a living plant.

What are different types of flowers?they can be classified in many ways: based on the presence of seeds, stems, leaves, and roots. The most accepted and popular classification of plants is based on whether they are flowering plants (angiosperms) or non-flowering plants (gymnosperms).
Plant morphology (or phytomorphology) is the general term for the study of the morphology (physical form and external structure) of plants. This is usually considered distinct from plant anatomy, which is the study of the internal structure of plants, especially at the microscopic level.
Vegetable characteristics of the three species, more have only been reported on a summary of the anatomical features of the seed coat, leaf, petiole and stem.
The structure, anatomy and morphology of mature seeds: an overview more general seed structural features: seeds are the dispersal and propagation units of the spermatophyta (seed plants): gymnosperms (conifers and related clades) and angiosperms (flowering plants).
Anatomical features: the appearance and structures which characterize certain groups of plants sum up to a great extent their ecological and physiological means of adaptation. Halophytes are no exception to this rule because of specific land typical structural characteristics which make them distinguishable from other groups of plants.
Palinuri plants from seed germination to the adult phase and analysed the morphoanatomical traits of plants at all stages of development.
Therefore seed characters can provide useful data in the delimitation and identification of species. The morphologic features of different seed structures provide a wide range of characters which can play an important role on the identification of taxa ( vaughan, 1968 ) and have traditionally been used to solve systematic and phylogenetic problems.
The hilum is the position of attachment of seed with its stalk, the funiculus. Near the hilum a small opening is present, called micropyle, through which water enters the seed. Sometimes a ridge is present beyond the hilum, opposite the micropyle, it is called raphe. It represents the base of the funiculus which becomes fused with integument.
The anatomy of monocot and dicot stem are similar, however, some notable differences are as follows: the hypodermis of the cortex in monocots is made of sclerenchymatous cells. Vascular bundles are numerous, but scattered, conjoint and closed, surrounded by the ground tissue.
