Explanation

• Plant spacing affects light, air circulation, and yield.
• Different cropping patterns have different row-to-row and plant-to-plant distances.
• In the hexagonal pattern, plants are arranged in triangles, making plant-to-plant distance longer than row-to-row distance.

• A flower is made of different parts: Calyx, Corolla, Androecium, and Gynoecium.
• Petals are usually colorful and fragrant to attract pollinators.
• All petals together form a distinct part called the Corolla.

Additional information:

• Calyx is made of sepals, usually green, protecting the bud.
• Gynoecium is the female reproductive part of a flower (carpel/pistil).
