Transport in Plants Plants perform the process of transportation in different ways in both short distance as well as long distances. The long-distance transport occurs mainly through vascular tissues (i.e., xylem, and phloem) and the process is called translocation. Over small distances, materials move through diffusion, cytoplasmic streaming, and active Read more…
Sexual Reproduction in Flowering Plants The flower is the reproductive part of a plant. In papaya, the flower is unisexual and contains either stamen or pistil and it may be bisexual as in mustard, and hibiscus. Parts of flower – sepals, petals, stamens, and pistils. Calyx – consisting of sepals, Read more…
Floral Diagram and Formula Floral Diagram: The diagram that illustrates the relative position and number of parts present in each whorl in a flower is termed the floral diagram. It provides information about the number of parts of a flower, their arrangement, and the relation they share. The diagram is Read more…
The Fruit – Morphology The fruit is a characteristic feature of flowering plants. It is a mature or ripened ovary that develops after fertilization. Sometimes fruit also develops without fertilization, which is called a parthenocarpic fruit. Type of fruits: parthenocarpic fruit: The fruit develops without fertilization, and it is a Read more…
The flower The flower is a modified shoot, meant for sexual reproduction, so it is a reproductive unit in the angiosperms. A typical or complete flower consists of four main parts i.e. Calyx and Corolla (as accessory organs) and Androecium and Gynoecium (reproductive organs). All these parts are arranged Read more…
Inflorescence in flowers The reproductive shoot-bearing group or cluster of flowers, that arrangement or specific pattern of flowers on the floral axis is called an inflorescence. The main axis of an inflorescence is called a peduncle. Inflorescence can be divided into the following types: Racemose Inflorescence Cymose Inflorescence Compound /mixed Read more…
Morphology of Leaf Introduction: Leaf A leaf (plural leaves) can be defined as a dorsoventrally flattened structure that arises from the node of the stem and bears a bud in its axil. The axillary bud later develops into a branch. They develop from shoot apical meristem and are arranged in Read more…
Stem- Morphology of flowering plants The Stem The stem is the ascending part of the axis bearing branches, leaves, flowers, and fruits. It develops from the plumule of the embryo of a germinating seed. The stem bears nodes and internodes. The stem is generally green in color when young and Read more…
Roots- Morphology of Flowering Plants The term Morphology is derived from Greek words: morphe– forms and logos– study Morphology is the branch of biological science that deals with the study of the form, size, shape, color, and external structure of organisms. In flowering plants is large diversity is found in Read more…
Angiosperms (Angios- vessel, sperma- seeds) Features of Angiosperms Angiosperms are flowering plants, in which the flower is developed by ovule and pollen grain. Seeds are found always enclosed in fruits in angiosperms. These are the most familiar plant-like mango, peas, coconut, wheat, and rice. The angiosperms diversified extensively during the Read more…
