1, Apple: The identification direction of apples can be carried out after the apples are ripe. Apples will ripen in autumn. After ripening, the weight of the fruit will increase and the color will become brighter. At this time, you can pick an apple and put it in your hand to observe the direction of the sunflower receptacle (the part at the bottom of the fruit handle) on the apple. The direction of sunflower receptacle is the direction of apple.
2. Sunflowers: Sunflowers don't have the same time to tell the direction as apples, just after they bloom. Sunflowers bloom in summer, and the inflorescence will face the sun, so we can determine the direction by observing the flowering direction of sunflowers. If the flower head of sunflower faces east, the south direction is on the left side of the flower head, and the north direction is on the right side of the flower head.
