Sunscald is the result of too much water being lost from heat and wind. This waxy layer in some instances makes it difficult for herbicides to stick to and enter the leaf. These serve as stored food for the seed. Leaves function in food storage and can act as protection, as in bulbs. Buds are undeveloped shoots and flowers.
Buds are classified terminal or lateral.
Another term for terminal is apical. Terminal buds can be identified by their location at the tip of a stem. Lateral buds are located at the sides of the stem. Cabbage and head lettuce are examples of very large terminal buds. Brussels sprouts are edible lateral buds.
