Question

the goal in grafting is to unite two plants ______.
a. to rapidly increase the number of desirable plants
b. so that they grow as one
c. to give plants stronger roots
d. all of the above

Explanation:

Grafting is a horticultural technique where two plant parts (a scion and a rootstock) are joined so they grow together as one. Option a describes propagation (like cutting or budding for rapid increase), option c is not the main goal of grafting (though rootstock can impact roots, the primary goal is union). Option b directly relates to the definition of grafting: uniting two plants to grow as one. Option d is incorrect as a and c are not the primary goal of the union in grafting.

Answer:

b. so that they grow as one
