Answer 1

The answer would be A. Seconedary growth is when a plant, or tree, begins to grow a wider trunk so it doesn't topple over from its height, or weight.

Answer 2

Answer is option A

Step-by-step explanation:

Secondary growth is the increase in girth of roots and stem of the plants by dividing lateral meristems cells and produce secondary tissues. Secondary growth is important to woody plants as woody plants are way taller than other plants and need more support in roots and stems. The secondary growth can be seen as annual rings in woody plants.
