Morphology Of Flowering Plants

Fruit is defined as fertilized ovary which consist of fruit wall (pericarp) developing from ovary wall and seed which develop from ovule. Maize grain is a caryopsis fruit in which fruit wall is fused with seed coat (i.e., one seeded fruit).

The edible part of cauliflower is fleshy inflorescence.

Aril is the edible part in the fruit of litchi. The aril is an accessory seed covering often formed from an outgrowth at the bare of the ovule. Fleshy thalamus is the edible part of apple (Pyrus malus). Juicy testa is the edible part of pomegranate (Punica granatum). Endocarpic juicy hairs are edible part of orange (Citrus sp).

In monocot stem, vascular bundles contain both phloem and xylem. Phloem lies towards the outside and the xylem on the inner side. Cambium is absent as the whole procambium is consumed in the formation of vascular tissues. The vascular bundles are, therefore, conjoint, collateral but closed. Phloem consists of sieve tubes, companion cells and a few phloem fibres. Phloem parenchyma is absent. Xylem is made up of vessels, tracheids, xylem parenchyma and a few xylem fibres.

Corm is a spherical, branched, vertically growing thick underground stem with more diameter than length. Corm usually bears reduced in temodes having few axillary buds in the axil of scale leaves, which grow into new corms. Adventitious roots are formed from the base of nodes. On approach of favourable conditions, the terminal bud forms the aerial branch which later on dries up , eg, Crocus sativus (saffron), Gladiolus, Colocasiaesculenta (arvi), Amorphophallus, etc.
