Types Of Flowering Plants

Many flowering plants reflect as much light as possible within the range of visible wavelengths of the pollinator the plant intends to attract. Flowers that reflect the full range of visible light are generally perceived as white by a human observer. An important feature of white flowers is that they reflect equally across the visible spectrum. While many flowering plants use white to attract pollinators, the use of color is also widespread (even within the same species). Color allows a flowering plant to be more specific about the pollinator it seeks to attract. The color model used by human color reproduction technology (CMYK) relies on the modulation of pigments that divide the spectrum into broad areas of absorption. Flowering plants by contrast are able to shift the transition point wavelength between absorption and reflection. If it is assumed that the visual systems of most pollinators view the visible spectrum as circular then it may be said that flowering plants produce color by absorbing the light in one region of the spectrum and reflecting the light in the other region. With CMYK, color is produced as a function of the amplitude of the broad regions of absorption. Flowering plants by contrast produce color by modifying the frequency (or rather wavelength) of the light reflected. Most flowers absorb light in the blue to yellow region of the spectrum and reflect light from the green to red region of the spectrum. For many species of flowering plant, it is the transition point that characterizes the color that they produce. Color may be modulated by shifting the transition point between absorption and reflection and in this way a flowering plant may specify which pollinator it seeks to attract. Some flowering plants also have a limited ability to modulate areas of absorption. This is typically not as precise as control over wavelength. Humans observers will perceive this as degrees of saturation (the amount of white in the color).

Types Of Flowering Plants

The hanging flowering plants can be defined as small evergreen shrubs, which can be grown in baskets or in hanging pots. These types of flowering plants can also be planted on fences and patios. They are traditional plants, which are planted in between the month of April to early June. These plants are habituated to more heat and plenty of water. There are plenty of hanging flowering plants, which includes: moss rose, lantana, fuchsia, verbena, sweet alyssum, etc.

Types Of Flowering Plants

A flower is the reproductive organ of all flowering plants. A single flower produces egg and sperm and the entire process of fertilization in plants occurs inside the flower. A single flower gives rise to fruit and seeds. In addition to reproduction flower plays a vital role in pollination by attracting animals, birds and other flies to transfer the pollen grains. According to the history, flowering plants came into existence about 135 million years ago. In fact, the food, which we consume every day comes from the flowering plants itself.

The Angiosperms are the Flowering Plants and there are around 250,000 to 400,000 different flower types. Fortunately they can be divided into two groups: Monocots and Dicots. Note that it is only the Flowering Plants that are Monocots or Dicots. Other plants such as Mosses and Ferns are neither.

The transition to flowering is one of the major phase changes that a plant makes during its life cycle. The transition must take place at a time that is favorable for fertilization and the formation of seeds, hence ensuring maximal reproductive success. To meet these needs a plant is able to interpret important endogenous and environmental cues such as changes in levels of plant hormones and seasonable temperature and photoperiod changes. Many perennial and most biennial plants require vernalization to flower. The molecular interpretation of these signals is through the transmission of a complex signal known as florigen, which involves a variety of genes, including CONSTANS, FLOWERING LOCUS C and FLOWERING LOCUS T. Florigen is produced in the leaves in reproductively favorable conditions and acts in buds and growing tips to induce a number of different physiological and morphological changes.

Hardy flowering plants can be defined as seasonal plants or a plant, which is adapted to the temperature, climate and to certain area. Hardy flowering plants have an ability to tolerate extreme cold, heat, wind, floods, and other geographic location, etc.

Types Of Flowering Plants

Flowering plants usually face selective pressure to optimize the transfer of their pollen, and this is typically reflected in the morphology of the flowers and the behaviour of the plants. Pollen may be transferred between plants via a number of ‘vectors’. Some plants make use of abiotic vectors — namely wind (anemophily) or, much less commonly, water (hydrophily). Others use biotic vectors including insects (entomophily), birds (ornithophily), bats (chiropterophily) or other animals. Some plants make use of multiple vectors, but many are highly specialised.

While land plants have existed for about 425 million years, the first ones reproduced by a simple adaptation of their aquatic counterparts: spores. In the sea, plants—and some animals—can simply scatter out genetic clones of themselves to float away and grow elsewhere. This is how early plants reproduced. But plants soon evolved methods of protecting these copies to deal with drying out and other damage which is even more likely on land than in the sea. The protection became the seed, though it had not yet evolved the flower. Early seed-bearing plants include the ginkgo and conifers. An early fossil of a flowering plant, Archaefructus liaoningensis from China, is dated about 125 million years old. Even earlier from China is the 125–130 million years old Archaefructus sinensis. Now, another plant (130 million-year-old Montsechia vidalii, discovered in Spain) takes the title of world’s oldest flower from Archaefructus sinensis.

The principal purpose of a flower is the reproduction of the individual and the species. All flowering plants are heterosporous, producing two types of spores. Microspores are produced by meiosis inside anthers while megaspores are produced inside ovules, inside an ovary. In fact, anthers typically consist of four microsporangia and an ovule is an integumented megasporangium. Both types of spores develop into gametophytes inside sporangia. As with all heterosporous plants, the gametophytes also develop inside the spores (are endosporic).

It is common to hear people say they are allergic to colorful or scented flowers like roses. In fact, only florists, gardeners, and others who have prolonged, close contact with flowers are likely to be sensitive to pollen from these plants. Most people have little contact with the large, heavy, waxy pollen grains of such flowering plants because this type of pollen is not carried by wind but by insects such as butterflies and bees.

Besides the Angiosperms (flowering plants) and the Gymnosperms (cone bearing plants), in the Plant Kingdom there are the  Bryophytes:  Mosses, Liverworts and Hornworts; and the Pteridophytes (ferns, horsetails and club mosses). The last two groups still use spores to reproduce. Spores (brown) can be seen on the backs of fern fronds in Spring. This is a type of sexual reproduction. And finally Legumes are often classed as another member of the Plant Kingdom all by themselves. Examples are beans, peas, and lentils.

Half-hardy: The term half-hardy plants are used in cultivation, to describe bedding plants, which are sown in heat in winter or early spring and planted outside after all danger of frost has passed. These plants require green house and warm temperature. They include plants like Busy lizzie, petunias, etc.Busy lizzie

Several groups of extinct gymnosperms, particularly seed ferns, have been proposed as the ancestors of flowering plants but there is no continuous fossil evidence showing exactly how flowers evolved. The apparently sudden appearance of relatively modern flowers in the fossil record posed such a problem for the theory of evolution that it was called an “abominable mystery” by Charles Darwin. Recently discovered angiosperm fossils such as Archaefructus, along with further discoveries of fossil gymnosperms, suggest how angiosperm characteristics may have been acquired in a series of steps.

Gas plants can take a few years to cultivate, but are easy to care for and, once flowering, give off an aromatic scent. Be careful though, the flowers and foliage are known to cause skin rashes for some.

A flower develops on a modified shoot or axis from a determinate apical meristem (determinate meaning the axis grows to a set size). It has compressed internodes, bearing structures that in classical plant morphology are interpreted as highly modified leaves. Detailed developmental studies, however, have shown that stamens are often initiated more or less like modified stems (caulomes) that in some cases may even resemble branchlets. Taking into account the whole diversity in the development of the androecium of flowering plants, we find a continuum between modified leaves (phyllomes), modified stems (caulomes), and modified branchlets (shoots).
