At which growth phase the growth rate is faster and reaches its maximum?
exponential phase
(ii) exponential phase (log phase) : when the growth rate becomes more and more rapid and reaches its maximum value, (iii) stationary phase (steady state) when the nutrients become limiting and growth slows down. This phase indicates the maturity of growth system.
In which of the following phases of plant growth does maximum growth take place?
initial slow growth (Lag phase), 2. the rapid period of growth (log phase/grand period of growth/exponential phase) where maximum growth is seen in a short period and 3.
Which phase of growth curve show rapid and maximum growth?
Log Phase
Complete answer: – Lag Phase: It is that phase when organisms are introduced into a new environment then the population growth starts slowly. – Log Phase: It is that phase where there is rapid growth and the maximum growth is reached in this phase. The conditions are ideal in this.
Which of the following phase is known as maximum population phase?
Following a period during which the growth rate of the cells gradually increases, the cells grow at a constant, maximum rate and this period is known as the log, or exponential, phase and the increase in biomass concentration will be proportional to the initial biomass concentration.
What is an exponential growth curve?
Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function.
What are the 4 phases of bacterial growth?
Bacterial colonies progress through four phases of growth: the lag phase, the log phase, the stationary phase, and the death phase. The generation time, which varies among bacteria, is controlled by many environmental conditions and by the nature of the bacterial species.
What are the 3 phases of growth?
They undergo three general growth phases: vegetative, reproductive, and ripening.
What are the 5 phases of growth in plant?
For humans, the progression is infant, toddler, adolescent, young adult, middle aged adult, and senior citizen, while plants go from seed to sprout, then through vegetative, budding, flowering and ripening stages.
What are the phases of growth?
There are three phases of growth – meristematic, elongation and maturation.
What is lag phase in population growth?
Lag time is defined as the initial period in the life of a bacterial population when cells are adjusting to a new environment before starting exponential growth.
What are examples of exponential growth?
10 Real Life Examples Of Exponential Growth
- Microorganisms in Culture. During a pathology test in the hospital, a pathologist follows the concept of exponential growth to grow the microorganism extracted from the sample.
- Spoilage of Food.
- Human Population.
- Compound Interest.
- Pandemics.
- Ebola Epidemic.
- Invasive Species.
- Fire.
What is the shape of the growth curve?
Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.
When does the maximum growth rate occur in a plant?
> Maximum growth rate occurs A. Stationary phase – This is the third phase in the growth curve. In this phase, plant exhibits declining growth activity. This phase corresponds to maturity of cells. B. Lag phase – This is the first phase of growth. In this, the growth will be slow but steady.
Which is the slower phase of growth in plants?
The geometric plants growth can be represented in the form of the following S-shaped graph having Sigmoid Growth curve in plants. Lag Phase- It is the slower phase where cell division is slow. Log Phase- Here, the growth is very fast and known as the exponential phase too.
When does the second phase of growth occur?
C. Exponential phase – This is the second phase of growth. This is a period of maximum growth. In this phase, the plant shows a rapid increase in its height. It is also called Logarithmic phase.
What happens in the geometric phase of growth?
The cell growth rate is very fast here in the geometric phase and when the growth comes at peak, it later starts becoming slow and later becomes steady due to some limiting factors. The geometric plants growth can be represented in the form of the following S-shaped graph having Sigmoid Growth curve in plants.
