phases of growth and factors influencing growth

Growth of an organism can be differentiated into the following perio..

During this phase the spermatocyte as well as its nucleus enlarges in size. It gets ready to undergo maturation divisi..

Factors affecting Plant Growth - 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) ..

Light - 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..

The growth factor of an exponential growth function is always => greater than 0 and less than 1 or less than 1 or equal to1 or greater than 1..

Summary - Growth is one of the most fundamental characteristics of living organisms. It is accompanied by differentiation. The growth cycle of an annual monocarpic angiosperm begins with the zygote which undergoes a period of dormancy. Later, the dormant embryo develops into a s..

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 a few are synthetic in n..

Find the growth rate, if the growth factor is 9. => 8 or 1 or 6 or 16..

The curve can be shown appearing slowly along the line and stabilizing. During the initial stage, i.e., during the lag phase, the rate of plant growth is slow. Rate of growth then increases rapidly during the exponential phase..
