Which of the following is a method of plant propagation that involves the use of plant parts?

Explanation

Plant propagation means making new plants. Farmers use different methods to grow more plants. Some methods use seeds while others use parts of existing plants.

Grafting is a method that uses plant parts. In grafting, farmers cut a branch from one plant and attach it to another plant. The two parts grow together to make one healthy plant. This helps combine the best features of different plants.

Seed propagation uses seeds, not plant parts. Tissue culture uses tiny plant cells in a lab. Layering bends a branch into soil, which is different from cutting and joining parts like grafting does.
