Question

Which is the significance of the tunica in plant growth? In the tunica, cell divisions are perpendicular to the stem axis, giving rise to thick layers of tissues covering the outside of the tip. In the tunica, cell divisions are parallel to the stem axis, giving rise to thick layers of tissues covering the inside of the tip. In the tunica, cell divisions are parallel to the stem axis, giving rise to thin layers of tissues covering the inside of the tip.

Answer 1

The answer is In the tunica, cell divisions are perpendicular to the stem axis, giving rise to thick layers of tissues covering the outside of the tip.

The tunica is a membranous structure which covers the plant organs. It is responsible for the characteristics of leaf edges and margins in the monocots. During the plant growth, perpendicular cell divisions regarding the stem axis result in the membranous structure outside of the tip.
