Consequences of Over Population/Impact of Population Growth - India is the best country to study the consequences of over population. Geometric growth in population has pushed our country into population explosion leading to number of serious consequences. Some of them are: Decr..

1) They produce food for all organisms 2) They provide beneficial substances like drugs, tannins, fibres, rubber, vegetable oils, fuel, condiments. 3) Some plants contain alkaloids which check growth of cancer cells. Example: Rosy periwinkle. 4) Plants release O 2 , cool environment by r..

- Rate at which population is growing. It is expressed on annual or decimal basis. It is difference between birth rate and death rate. Each one of the above derived parameter has specific significance in the study of population. Many of the above parameters are simultaneously studied at rural a..

f r . Mangrove plants exhibit vivipary. Flowering is under the control of daily length of light (photo period) and temperature. Depending upon the photoperiodic responses, 3 categories of plants exist namely SDP, LDP, and day neutral plants. Flowering is a phytochrome-mediated process. The site o..

Population supplies trained and skilled labour to the country. It is important for the economic growth. If the skilled labour pioneer is properly utilised in industries, it will result in large scale production and the cost of production will fall, the price of products will dec..

The growth and yield of food crops are also seriously damaged by various insects. Each insect attacks the crop in its own style and damage the crop to complete its own life cycle. The insects attack almost all parts of crop and the damage may be direct loss of economic product o..

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 light d..

Advantage of the Regulation of Gene Action - An operon is the unit of transcription. When excess protein is present, it is no longer economical for the cell to use up its energy and materials in the synthesis of enzymes that are not immediately needed. Hence, the protein synthesis is stop..

In tissue cultures of parenchyma, mitosis is accelerated when both auxin and cytokinin are present, but no response is seen with auxin or cytokinin present alone. Cytokinin - auxin ratio and their interaction controls morphogenetic differentiation in shoot and root meristem..

Gradients of Biodiversity - Biodiversity varies with change in latitude or altitude. The diversity increases as we move from high to low latitudes (i.e., from poles of equator). In the temperate region, the climate is severe with short growing period for plants while in tropical rain fore..
