fig. 1.2 - Energy transfer and energy transformation Examples of energy transformation 1. Photosynthesis - in which green plants transform radiant solar energy into chemical energy that gets stored as potential energy in carbohydrates. 2. Bioluminescence -in which chemical energy is trans..

Vectorless Gene Transfer - Gene transfer can be effected by certain means that do not use vectors. These include a. Electroporation: Temporary holes are formed in the plasma membrane of the host cell by applying a high voltage. These pores permit entry of foreign DNA. b. Chemica..

When the molecule is formed by transfer of electrons (ionic bonding) the transfer takes place from electropositive atom to electronegative atom. In the example below, Na is electropositive and Cl is electronegative. If the molecule is formed by sharing of electrons (covalen..

Only when a particle loses electrons can the other particle accept electrons. In other words, a particle can accept electrons only if another particle gives out electrons. This electron-transfer process is possible only when both species are present in the reaction. Hence, oxidation and ..

Pollination - Pollination is defined as the transference of pollen grains from the anther of a flower to the stigma of the same flower or another flower belonging to the same species. Two types of pollinations have been broadly recognise..

Transfer of pollen grains to the stigma is called pollination. If the pollen grains are transferred to the stigma of the same flower, the pollination is called self-pollination or autogamy . If the pollen grains are transferred to the stigma of another flower of the ..
