The Life Cycle of Flower Plants

Flowers are beautiful, fragrant, and draw pollinators insects to pollinate them, serving also to disseminate seeds across their environment.

Pollen grains that land on the stigmas of other flowers of the same species germinate to form a tube that descends through style and into ovary where male reproductive cells, known as gametes, unite with female ones through fertilization to create ovules for fertilisation.


Many plants begin as seeds enclosed within a protective seed coat, which serves to nourish their embryonic (baby) plants until they can grow on their own.

Seeds require specific conditions in order to germinate and begin growing into new plants, including temperature, water and oxygen availability. Without these essential elements in place, seeds will fail to sprout and remain dormant or inactive until more suitable conditions arise.

At an ideal temperature for germinating seeds, 65 to 75 degrees Fahrenheit is optimal. At this temperature, seeds begin to absorb water through imbibition; when enough has been taken up by cells within their seedcoat cells, pressure builds and causes expansion; eventually this allows it to rupture open its seed coat and enable germinating to occur.

A seed’s cell wall will absorb oxygen, prompting it to begin developing roots which will enable it to absorb nutrients from its environment. Over time, however, it will grow its own leaves that it uses for photosynthesis – eventually blossoming into flowers as it matures further.


Germination is the initial stage in any plant’s life cycle. When this stage has completed, a seed begins to germinate and sprout roots, stems and leaves that connect back down into the soil for storage of water and nutrients while their stems and leaves push upward towards sunlight for photosynthesis, producing food for photosynthesis through photosynthesis processes. Flowers also begin developing at this point – essential parts of its reproduction.

Flowers contain both male and female parts of a plant that must be pollinated to produce seeds. The male component, the stamen, consists of an anthers attached to long filaments; while its counterpart, known as pistil, comprises stigma, style and ovary – with pollen grains passing by being caught by stigma, then entering style to enter ovary where they fertilise egg cells to create seeds.

Flowers draw insects and animals in to help the process by producing sugary nectar, which attracts insects such as bees that consume it to spread pollen from flower to flower and stick it onto them as they travel between flowers eating the nectar. As bees travel between flowers consuming nectar, some pollen sticks onto them when coming into contact with parts that produce it – this process of pollination transfers pollen onto its body when visiting another bloom, contributing significantly to plant life cycle and its survival.


Plants require growth in order to survive and reproduce. Germination occurs when seeds start germinating; once their first sprout appears it is known as a seedling. A seedling needs roots, stems, leaves and flowers before reaching maturity when pollination can produce flowers and produce further seeds from its own pollen source – starting a continuous cycle!

Flowers begin as buds protected by modified leaves known as sepals and petals, usually greenish in hue and similar in shape to reduced leaves, but may feature brightly-hued designs in order to draw insects that assist pollination. Collectively, sepals and petals form what is known as the calyx or perianth structure and contain male sexual parts known as stamens as well as female reproductive parts called pistils for fertilisation purposes; pollen grains produced by stamens travel from these petals into fertilisation chambers within pistils where pollen grains travel from stamens to fertilisation in pistils where pollen grains are fertilised, finally ending up back inside an ovary which contains their seeds as seeds potential seed producers!

Scientists are discovering new insights into how flowers have developed their vast variety. By decoding recipes stored within plant genes for creating different kinds of blooms – for instance, some flowers feature petals resembling leaves while others use petals that resemble those found on lilies or tulips – scientists are gathering more clues as to their development and use of basic tools used by their parts when shaping and size are determined.


Pollination in flowering plants involves the transfer of male gametes (sperm) from anthers to stigmas of different or the same plants, which results in fertilization and seed production, thus perpetuating their species and reproduction. Pollination is essential in both gymnosperms and angiosperms, although more so with angiosperms; pollinators such as bees, butterflies, birds, bats, and wind carry out this task.

Pollen grains produced by flower male reproductive parts (anthers) can be moved by wind currents or pollinating animals to the female reproductive parts (stamens) of other flowers by cross-pollination, also referred to as pollination between species, thus producing hybrid plants which can then be produced naturally or by plant breeders.

Once pollen reaches the stigma, it combines with egg cells in the ovary to produce a seed that then becomes fertilized by light from above and fertilizes all three sections of its embryo: root, stem and leaf parts which have all the characteristics to form into a new plant when conditions allow.

Once the seed is mature, a flower forms a fruit with its seeds contained inside, which are then dispersed (disseminated) via either wind or animals – for instance dandelion seeds may be spread by wind while cocklebur seeds become attached to animal fur and feathers and hitchhike to new places before germinating into new plants – thus continuing the cycle.


Plants play many functions in society: they produce food, serve as tree building material and add beauty and fragrance. But their primary reason for growing is simply reproduction – so that new seedlings may sprout.

Pollinating flowers to produce seeds requires pollen grains landing on their stigma – usually composed of long tubes containing female reproductive organs like an ovary at its top and male organs such as anthers supported by filaments – on other flowers in their same species. Once pollen enters this process, male and female gametes join to form fertilized cells which then develop into seeds.

Most flowers rely on insects and other creatures for pollination. A bee, for instance, flies from one flower to the next in search of nectar; while doing this it rubs its legs and body against parts of each flower that produce pollen that sticks onto its legs or body and collects pollen grains that it passes on to other flowers.

Flowers possess both male and female reproductive parts, but fertilization occurs only when pollen lands on a stigma of another flower of the same species. When this happens, fertilisation happens within its cells containing seeds which form inside a fruit. Asexual reproduction also exists among some plants: this involves stems or roots growing sideways above ground that develop into new plants far removed from their parent plant.


Plants rely on their roots for nourishment from the soil, their stem for transporting water and food from its leaves to the rest of the plant, and sunlight to convert energy through photosynthesis. Once fully grown, mature plants produce flowers as an early sign that fruit production will follow soon thereafter containing seeds that will form new plants in time.

Pollination is essential for producing fruit from flowers; this process occurs when male flower parts (anthers) produce sperm which is then distributed via bees, bats or the wind to female parts (stamens or pistil). When this sperm meets up with an egg in its stigma and fertilization occurs, new seeds form.

Flowers are often the first components to develop in plants, yet for fruition to take place they must first be fertilized with pollen or pollen from another flower. Following fertilization, their fertilized ovaries grow and mature into fruits – these organs reside within their flower’s gynoecium which houses stigmas, styles and ovarian cysts located centrally within its flower head.

Some flowers can reproduce asexually, although this form of reproduction is less prevalent. Asexual reproduction involves only one parent and results in exact copies of the original plant as offspring. If a plant doesn’t require fertilization process to reproduce fruit it won’t produce fruit but continue living its natural cycle instead.
