Angiosperms
Angiosperms - Angiosperms represent the most advanced group of vascular plants. They are commonly called 'Flowering plants'. They exceed all other major groups of living plants in number and diversity. Angiosperms grow in almost every kind of habitat. They occur in ver..
Angiosperm Classification Introduction
Introduction - There have been several attempts to classify angiosperms, the flowering plants. One of the earliest attempts in this direction was that of Carolus Linnaeus. He attempted a classification of angiosperms based on the characteristics related to flowers. Subsequent ta..
Angiosperm Morphology Summary
Summary - Angiosperms represent the most advanced group of plants. The angiosperm plant body consists of an underground root system and an aerial shoot system. The shoot system contains vegetative parts and reproductive parts. The root serves two primary functions anch..
Sexual Reproduction
In flowering plants, flowers have taken the place of conventional sex organs, and the ovules which later on develop into seeds are enclosed within an ovary. The sexual reproduction in angiosperms involves the fusion of two gametes, the male and the female. The male gametes..
Asexual Reproduction
Asexual Reproduction - New individuals are produced from a single parent without the act of fusion of gametes. The new individuals so formed are generally identical to the parent plant, as only mitotic divisions take place during their development. Regeneration of new plants from portions..
Reproduction in Flowering Plants Summary
Summary - Reproduction occurs by vegetative propagation, asexual and sexual reproduction. Vegetative propagation through artificial method can be done by cuttings, layering and grafting. Pollination refers to the transference of pollen grains from the anther of a flower to the s..
Special Modes of Reproduction
Parthenocarpy - In angiosperms, the fruits are usually formed after the process of fertilisation. In certain plants, however, the fruits are formed without the act of fertilisation. Such fruits are called parthenocarpic fruits and the phenomenon is known as parthenocarpy. Parthenocarpic f..
Introduction
There have been several attempts to classify angiosperms, the flowering plants. One of the earliest attempts in this direction was that of Carolus Linnaeus. He attempted a classification of angiosperms based on the characteristics related to flowers. Subsequent taxonomists also ..
Flower
The angiosperm plants produce characteristic structures called flowers for the purpose of reproduction. A flower is defined as a modified vegetative shoot meant for sexual reproduction. The flower consists of a very short axis on which whorls of different parts a..
Inflorescence
Flowers are the reproductive structures in angiosperms. Each flower is a modified shoot adapted for purposes of reproduction. Flowers may occur either singly or in clusters. When clustered, the flowers are generally arranged on branches, which are quite distinct from t..
