1. Vascular tissue is the xylem and phloem. In leaves these are the veins. Tracheids are part of the xylem. Petioles are the long skinny base of the leaf that attaches to the stem. Guard cells are part of the stomata.
2. B is probably your best choice.
Forestry is the management of trees and related natural resources. Silviculture is related, being the actual tending of the trees. Farming is the systematic raising of plants and animals. Gardening is small scale raising of plants.
