Question

the main difference in plants propagated by the process of separation and by the process of division is that ______.
a. division is a natural method of propagation; in separation, plants must be cut apart
b. separation is a natural method of propagation; in division, plants must be cut apart
c. separation is done in the spring of the year; division is done in the fall
d. there is no real difference

Explanation:

To solve this, we analyze plant propagation methods:

• Separation: Involves naturally detaching plant parts (e.g., bulbs, offsets) without cutting.
• Division: Requires cutting or separating clumps (e.g., perennials) into sections.

Option a: Incorrect (division is not “natural” in the sense of no cutting; separation is natural).
Option b: Correct (separation is natural (parts detach on their own), division needs cutting apart clumps).
Option c: Incorrect (timing varies, not a defining difference).
Option d: Incorrect (there is a clear difference).

Answer:

b. separation is a natural method of propagation; in division, plants must be cut apart
