How to calculate the average growth rate of a plant?

How to calculate the average growth rate of a plant?

Calculate the average using the growth rate formula. The equation for the growth rate formula is where S1=first measurement, S2=second measurement, and T equals the number of days between each. This is an extremely general figure. Plant growth rate is extremely fluid and can be subject to major variations day by day.

Which is the last phase of plant growth?

The growth in size or increase in number of cells if plotted against time the graph shows ‘S’ shaped curve known as sigmoid growth curve as shown in the figure. In the annual plants the last phase i.e. steady state phase is followed by senescence i.e. arrest of growth and death.

How is the length of a plant measured?

As the plant grows in length the pulley rotates and needle attached to the pulley moves down the scale. From this, growth in length of the plant can be measured at a given interval of time. The actual growth in the length of a plant is measured as follows.

How does the number of cells affect the growth of a plant?

Increase in the number and size of cells by itself cannot account for the development of an organized plant. For example, when a seed is sown, it does not become a larger seed but it grows as a seedling. Thus, growth is always accompanied by differentiation. Differentiation is the transformation of identical cells into different tissues.

How long does it take a plant to grow 4 cm?

Check all that apply. The rate of change is 4. The rate of change is 1. The rate of change is . The plant grows 4 cm in 1 week. The plant grows 1 cm in 4 weeks

Which is an example of an exponential growth model?

The general exponential growth model is. y = C ( 1 + r) t , where C is the initial amount or number, r is the growth rate (for example, a 2 % growth rate means r = 0.02 ), and t is the time elapsed. Example 1: A population of 32, 000 with a 5 % annual growth rate would be modeled by the equation:

How is the growth rate of a population modeled?

A population of 32, 000 with a 5 % annual growth rate would be modeled by the equation: with t in years. Sometimes, you may be given a doubling or tripling rate rather than a growth rate in percent.
