You are a botanist who is immersed in your attempt to increase a certain property in your plant of study. To that end, you induce a mutation that doubles the amount of vascular cambium (a type of meristem)in your plant. Assuming this brings the desired effect, what exactly was the property that you sought to increase?

A)production of new growth at the tip of stems
B)production of secondary xylem and phloem
C)production of only xylem to make wood
D)production of bark only
E)production of new leaves

Option B.

Production Secondary xylem and phloem

Explanation:

Cambium in plants is a kind of meristem or layers of dividing cells that produced more xylem and phloem which help to transport water and nutrient to increase plants growth.

When you induced the mutation that doubles the amount of cambium, it increases the production of secondary xylem and phloem ( conducting tissues). These tissues conduct water (xylem) and nutrients (phloem). By transporting water and nutrients, there is increase In plants growth and thickness.

cells spend most of their time in interphase

well, i believe that the answer is 2. : 3
