A lily ( Lilium sp . ) is a efflorescence plant relegate as an flowering plant , a plant that form ejaculate in a protective , fleshy wrist bone . The liveliness hertz of the lily is aboveboard , begin with sprouting of the seed and maturation into a plant with leaves , theme and theme . At maturity , the lily will form a flower , complete with male and distaff floral share that will join during fertilization , often assisted by the conveyance of pollen to the ovary via an worm . Once fertilize , the ovary evolve into a fertile seed .

Germination

Once the seed of the lily is exposed to appropriate sum of light , warmness and moisture in the topsoil , the plant life conceptus will swell and break through the seedcoat . A taproot and shoot will emerge . The cotyledons , or initial leaves , will poke up from the soil and become dark-green as the initial chlorophyll paint are formed and photosynthesis begins .

Plant Growth

The juvenile plant will continue to grow , forming more leaves and roots as more food is produced during photosynthesis and the roots continue to occupy water and food . With time , spare nutrient will permit the formation of a bulb in the ground – a collection of scale of measurement - like tissues in a rounded mass .

Perennialization

As the first growth year ebbing and autumnal frigidness and hoarfrost kill back the above - ground foliage , nutrient and food for thought will be located in the secret bulb to winter .

This perennial plant re - issue in the warmth of spring , utilize the stored energy from the bulb for the initial increment jet of prow and leaves . Throughout the summertime , the plant gains strong suit and vigor as it makes more food during photosynthesis , enough energy in that flowering can be undertaken .

Flowering

The mature plant will manufacture appropriate endocrine to start blossoming allot to its genetic code , unique for each coinage . root word tips will differentiate into flower buds , eventually puff up to let on a complete heyday , one with both male and distaff social organization .

In the pith of the bloom is the female pistil with its lower ovary , neck - same style and topped by the stigma , the point where the manlike pollen is received . Surrounding the pistil is a ring of six male person - gendered stamen , each with a thread - like stem called a filament and lead by the pollen - shed sac in the anther .

Pollination and Fertilization

enzyme are let go by the pollen grain and the pollen penetrates the long style tubing , finally detect its manner to the ovary . fecundation take place . The fusion of the pollen ’s manly DNA with the ovary ’s female desoxyribonucleic acid results in the formation of seeds .

Maturation of the Seed

week after fertilization , the plant has expended Energy Department into the development of the seeds . The vain ovary , front like a plump seedcase , finally dry out and browns when the seed are good . The pod sally and split clear , releasing the seminal fluid to dribble to the productive grime below . The seed rests in dormancy in the autumn and winter , awaiting the idealistic condition for germination the following spring .
