Question

Trees showing seasonal activities represent what kind pf growth curve?

• A. Linear
• B. Sigmoid
• C. Double sigmoid
• D. J shaped

Answer 1

The correct option is B Sigmoid

Plants showing seasonal activities represent a sigmoidal growth curve. In such a growth curve the initial growth is slow (lag phase). It then increases rapidly in an exponential manner (known as the log phase). After this, the nutrient supply decreases and growth slow down leading to the stationary phase. Such a curve is S-shaped and is known as a sigmoidal curve. In seasonal plants, in the spring season when leaves start growing, plants are said to be in the lag phase, the summer season is known as an exponential phase as plant growth is maximum and winter stationery/ resting phase. So, the correct option is 'Sigmoidal'.
