In sigmoid growth curve, the exponential phase slows down leading to a stationary phase due to
Open in App
Solution
The correct option is C limited nutrient supply
Geometric growth is represented by an initial lag phase of slow growth, followed by exponential or log phase of rapid growth and leads to a stationary phase, where growth slows down. We get a sigmoid curve. They begin with a smaller number of cells initially, and later on, there is a rapid growth at the exponential phase. Here, each and every cell divides and the daughter cells grow and continue to divide. This cycle continues. But, exponential growth cannot be sustained for long. Some cells die. Limited nutrient availability causes slowing down of growth, culminating in a stationary phase. Besides nutrient exhaustion, adverse climatic conditions such as extreme temperatures, humidity or absence of sunlight can slow down the plant growth. There may be a decline phase following a prolonged stationary phase. A sigmoid curve is typical to an organism growing in a natural environment. It also occurs in cells, tissues and organs of plants. The equation that represents exponential growth is
W1=W0 ert
W1= final size attained
W0= initial size to begin with
e= base of natural logarithms
r= relative growth rate/ efficiency index= the ability of plant to produce new plant material
t= time of growth
Plants respire throughout their life to meet the energy requirements.
Genetics determines the plant characteristics overall, but does not directly inhibit growth.
Differentiation is the process in which the cells mature to perform specific functions. Differentiation is observed throughout the growth and developmental phases of the plants.
