plants as indicators

Plant Kingdom - The following classification 'telescope' clearly indicates the mechanism behind the classification of the plant kingdom. Eichler in 1883 suggested a system to classify the plant kingdom which is well accepted. He said that the plant ..

(sugarcane) 80 9. Ophioglossum (Adder’s tongue fern) 1262 In some cases, males have one chromosome less than females. In the round worm Coenorhabditis males and females have 11 and 12 chromosomes respectively. In the cockroach Blatta orientalis males and females have 23 and 24 chromosomes res..

In the plant Mirabilis jalapa, commonly called as four'o clock plant, the inheritance of flower colour is an example for incomplete dominance. The plant produces two types of flowers red coloured and white coloured. This condition is an example for a pair of contrastin..

There is increasing evidence to suggest that a flowering hormone exists in plants. This is has been supported by a number of grafting experiments. A short day plant kept in long day conditions can be induced to flower, if a properly photo induced plant is grafted on it..

Dedifferentiated cells are specialised cells, which can revert back to an embryonic state. Dedifferentiation is seen in dicot plants, particularly at the time of secondary growth. It is also seen in the process of regeneration that involves the ability of an animal to develop the lost pa..

. Litmus, a purple dye extracted from the lichen plant, is commonly used as an indicator in laboratories. Acids change the colour of litmus solution to red, and bases change the colour of litmus solution to blue. Turmeric is another common household indicator. A stain ..
