Question

plants such as airplane plants grow branches with baby plantlets on them. these plantlets develop a root system that then grows into the soil to create a new plant but receives their nutrients from the parent until they are \disconnected\ from the parent plant and must then survive on their own. which form of asexual propagation is used with the airplane plant? options: division, cuttings, separation, layering

Explanation:

To determine the form of asexual propagation (note: the question says "sexual" but it's asexual) for airplane plants:

• Division: Separates clumps of plants (not matching the baby plantlets on branches).
• Cuttings: Involves cutting a stem/root (not matching the plantlets on branches).
• Layering: Requires bending a stem to root (not matching the plantlets on branches).
• Separation: Involves removing plantlets (offsets) from the parent plant, which matches the airplane plant’s baby plantlets growing roots and detaching.

Answer:

separation (the option labeled "separation")
