Plagiotropic growth refers to growth at right angles to the main axis, often producing what?

• A. Terminal flowers on the main stem
• B. Secondary branches or roots at right angles
• C. Leaves at the apex only
• D. Growth along the main axis

Answer: (B)

Plagiotropic growth means growing at an angle to the main axis, usually sideways. Because the growth is directed perpendicular to the main stem or root, it often produces structures that branch off at right angles to that axis. That’s why secondary branches or lateral roots forming at right angles to the main axis is the typical outcome. By contrast, growth along the main axis would extend the primary trunk or root rather than create lateral structures, and options about terminal flowers at the tip or leaves only at the apex don’t describe sideways, perpendicular growth.
