Question
The following experiment was performed to test the effect of auxin on plant growth: Study and answer question.
The auxin was dissolved in a gelatin block; gelatin does not affect the biological activity of the auxin. Several plant seedlings were prepared in a gelatin block; gelatin does not affect the biological, activity of the auxin. Several plant seedlings were prepared as described above and growth was measured every 5 days.
Based on the results of the experiment, one can conclude that the tip of the plant contains ....................

Solution
The correct option is B Plant 4 grew faster than plants 2 or 3
In the given picture, plant 4 will grow faster because tip is removed and auxin with gelatin is applied. This makes the plant to divide its cells mitotically. Multiplication of meristem cells are random and results in apical dominance. Thus, it grows faster than plants 2 or 3.
