FLOWERING PLANTS Meaning and
Definition
-
Flowering plants, also known as angiosperms, are a group of plants belonging to the division Magnoliophyta. They are the most dominant and diverse group of plants on Earth, consisting of more than 300,000 known species. The term "flowering" refers to the reproductive structure called the flower that distinguishes these plants from others.
Flowering plants are characterized by their ability to produce flowers, which contain the male reproductive parts called stamens and the female reproductive parts called pistils. Flowers are responsible for sexual reproduction in angiosperms, facilitating the fusion of male pollen with the female ovules to produce seeds. This unique reproductive mechanism has allowed flowering plants to evolve various adaptations for successful pollination by insects, birds, mammals, and even wind.
In addition to flowers, another key feature of flowering plants is the production of fruits, which develop from the fertilized flowers. Fruits are a means of protection and dispersal for the seeds, providing them with nutrients and facilitating their spread to new locations. This adaptation has contributed to the incredible success of flowering plants, as it allows for wider seed distribution, enhancing their chances of survival and colonization.
Flowering plants exhibit a wide array of sizes, shapes, and growth habits, ranging from small herbaceous plants to tall trees. They also possess a diverse range of ecological roles, from providing food and shelter for animals to contributing to the oxygen cycle and carbon sequestration. Humans have extensively cultivated flowering plants for purposes such as food production, ornamental purposes, and medicinal uses. Overall, the evolution and proliferation of flowering plants have had a profound impact on the planet's biodiversity and the functioning of ecosystems.
Etymology of FLOWERING PLANTS
The word flowering comes from the verb to flower, which originated in the 14th century and is derived from the Old French word flour meaning flower. This Old French word can be traced back to the Latin word flos, which also means flower.
The term plants is derived from the Latin word planta, which originally meant a shoot or cutting for propagation. It later evolved to refer to any living organism with the ability to grow and produce its own food through photosynthesis.
When these two words are combined, flowering plants refers to a group of plants that have flowers as their reproductive structures, enabling sexual reproduction. It is a common term used in plant taxonomy to describe the group known scientifically as angiosperms.
