A petal is a part of a flower. Most flowers have a ring of brightly colored petals surrounding the center part of the blossom.
花瓣是花的一部分。大多数花都有一圈颜色鲜艳的花瓣围绕着花的中心部分。
Petal comes from the Greek word petalon, meaning "leaf, thin plate." A petal is the lovely colorful leaf-like ring around the center of the flower, a thin plate for a fairy. The petals make up a flower’s corolla, surrounding the center. You can rip them off one by one as you say, “She loves me, she loves me not” until the last petal is picked. She loves me!
花瓣来自希腊语单词petalon，意思是叶子，薄板。花瓣颜色各异，像叶子一样的形态围绕在花的中心一圈。花瓣整体组成一个花冠，围绕着花的中心。经常有人会这么一边说“她爱我，她不爱我，她爱我，她不爱我...”，一边一片一片地摘下花瓣，直到最后一瓣被摘下。
除了“花瓣”是一瓣一瓣的，
常见的许多蔬菜水果也有类似的结构
比方说
橘子剥皮后，呈现一瓣一瓣的
做菜常用的“蒜”也是一瓣一瓣的
这些“瓣”的英文跟“花瓣”不同
英语中有对它们专门的单词
