How Do Flowers Reproduce?
The distribution and use of flowers are a cultural tradition that dates back to the earliest days of recorded history. Flowers have played a significant part in human culture through various religions, all of which attribute different meanings to different colors of flowers, different types of flowers, and the manner in which they are given. A flower, sometimes called a bract, is the reproductive organ present in flowering plants that does not have leaves. The primary biological purpose of a flower is to encourage reproduction, normally by giving a triggering mechanism for the union of male and female sperm cells. Some flowers, such as the love-sleeve or Carnation, contain sugars that serve this purpose in the process of fertilization.
The flowers of today were formed from more than one type of ancestor. Flowering trees, such as those that produce orchids, date back about a hundred million years ago. Asters, crocuses, and pearly freesias, all from the Permian/Paleocene geological period, belong to the same group of flowering plants as the orchids that lived around the same time. This group collectively called Planktonic fungi, branched into two main groups: the members of the Planktonicales family that produce orchid flowers and the members of the Planktonicidae family that produce gymnosperm flowers.
The orchid began as the basic form of a living organism that had evolved into a fully functional reproductive part. The process of evolution began when a single cell moved from a different environment to become the first flower in a process called photosynthesis. The chloroplast of this new flower was itself fertilized by pollen from an animal cell. The first true flower was the result of a duplication of the photosynthesizing cell. In the last three billion years since the evolution of plants from algae to trees, the method of photosynthesis has been completely transformed, resulting in a far more complex process of producing a living thing from nothing.
One of the first types of flowers to evolve were the sepals. These flowers are composed of two reproductive parts: The prothallium or the sepal, which is actually a single cell plus a connecting palpal organ and the ailium or orchid petals. Sepals grow or are joined together, from the tips of petals and grow down towards the base of the plant. Most sepals fall off at the lowest part of the flower. Petals consist of spongy reproductive parts surrounded by a semi-translucent cuticle, while the album is composed of the pigment called phloem that filters out sunlight.
Flowering plants make their own food through photosynthesis and use nectar as their sole food. Flowering plants only produce flowers for one year before they drop their reproductive or sensuous petals and cease to exist. They will produce more flowers the following year if they are in an alkaline environment with plenty of water. This is why you see all types of flowers in alkaline soils: it is their best chance to reproduce.
A bract is a group of flowers that consist of a single reproductive or sensuous cell. Bracts consist of different parts that cannot be interchanged like the other parts of a plant. The ovary, which is a glandular structure at the base of a stem, can be detached and eaten by insects or birds. The stamen, which is a glandular structure at the top of the flower consisting of different parts, can also be detached and eaten by insects. Lastly, the anther is a glandular part of the flower consisting of different parts that can be detached.
Flowering plants are very different from other organisms. Flowering plants reproduce both by seeds and by nectar. The reproductive part of a flower begins at the bottom of the plant and works its way up through the whole plant. Nectar is the liquid that nourishes the plant and has to pass through a series of glands before reaching the leaves.
It is amazing how life works in nature. In the same way, flowers reproduce both by growth and by the accumulation of nectar. It would be very hard to imagine a living creature existing without either a procreation process or the accumulation of nectar for sustenance. Most plants make use of both processes, but there are some that reproduce by means of somatic cells.
