1. Definition of Pollination: - Pollination is the process of transferring pollen grains from the anther (the male part of the flower) to the stigma (the female part of the flower). This is a crucial step in the reproductive process of flowering plants. 2. Definition of Fertilization: ...
roots such as a corm, stem tuber, rhizomes and stolon undergo vegetative propagation. diagram of asexual reproduction in plants sexual reproduction in plants takes place through pollination in which the pollen grains from the anther of a male flower transfer to the stigma of the female flower....

Apart from possible effects on human health, there is also public concern that 5G and other telecommunications sources may affect the environment since animals and plants have natural responses to specific types of natural EMF, including migratory patterns and pollination [7]. RF EMF is physically ...
The first gametophytic structure is the modification of microspore mother cell into the pollen grain. The pollen grain grows into the male gametophyte on germination which is initiated before pollination takes place. Inside the microsporangium, Pollen mother cell (PMC) undergoes meiosis and results in...
contains carotene and xanthophylls. they impart a specific colour to flowers and fruits and help in pollination and dispersal of seeds leucoplast: they are colourless and store various food products, e.g. amyloplasts- store starch, proteinoplasts or aleuroplasts- store proteins, elaioplasts- ...
