Final answer:
The experimental hypothesis for investigating the effect of fungal pathogen lectin on the number of cells undergoing mitosis in a different plant using root tips.
Step-by-step explanation:
The experimental hypothesis for investigating the effect of the fungal pathogen lectin on the number of cells undergoing mitosis in a different plant, using root tips, could be formulated as follows:
If the fungal pathogen lectin is applied to root tips of a different plant species,then the number of cells undergoing mitosis in the root tips will be significantly higher compared to the control group (no lectin application).
This hypothesis suggests that the fungal pathogen lectin has the potential to induce mitosis in root apical meristem tissues of plants, leading to increased cell division. By comparing the number of cells undergoing mitosis in the experimental group (plant treated with lectin) to the control group (plant not treated with lectin), the hypothesis can be tested.
