factors influencing bacterial growth

The inter-ionic attraction It is the intersection between the ions of the solute at low concentrations. It is not much at low concentrations the inter-ionic cone is very less, but at high concentrations it is appreciabl..

Plant growth is influenced by a number of external and internal factors. The external factors affecting plant growth are: i) light ii) temperature iii) oxygen iv) carbon dioxide v) soil water vi) soil nutrients The internal factors affecti..

Low ionisation energy Ionisation energy is the amount of energy, which is required to remove the most loosely bound electron(s) from an isolated gaseous atom to form a positive ion. In forming an ionic bond, one atom must form a cation by losing one or more electrons. In general, eleme..

Wound healing is due to accelerated mitosis. This is mediated by proteins called growth factors which act local..

Green colour of the visible spectrum is ineffective in inducing flowering whereas blue colour induces poor flowering. The wavelength 580 nm to 680 nm in the red portion of the spectrum has been found to be most effective for inducing flowering. Flowering is a phytochrome mediated process. It occurs..

Growth regulators - There are several known growth regulators. Some of them like auxins, cytokinins are growth promoting while others like abscissic acid, ethylene are growth inhibitors. Most of the growth regulators are synthesized by plants while ..

The effect of light on growth can be studied under 3 headings light intensity, light quality and duration of light. Growth is generally favoured by darkness, but light is indispensable because of its role in the manufacture of food. Young plants growing in the absence of l..

Find the growth rate, if the growth factor is 13. => 10 or 1 or 24 or 12..

Growth Regulators - The growth of plants is regulated by certain chemical substances, which are synthesized by the plant in very small quantities. These substances are formed in one tissue or organ of the plant and are then transported to other sites where they produce specific ..
