Questions & Answers about yèpiàn fāhuáng le, xūyào xiūjiǎn.

Why does the sentence use 叶片 instead of 叶子?

叶片 is a more formal or botanical word for a leaf blade or leaf. It often sounds a bit more technical than 叶子, which is the everyday word for leaf.

So:

• 叶子 = everyday, common speech
• 叶片 = more formal, plant-related, descriptive

In a gardening, plant-care, or botanical context, 叶片发黄了 sounds very natural.

What does 发黄 mean here? Why not just use 黄?

发黄 means to turn yellow, to become yellowish, or to show yellowing.

The pattern 发 + color/adjective often means that something is developing that quality:

• 发红 = turn red
• 发白 = turn pale / white
• 发黑 = turn black / dark
• 发黄 = turn yellow

If you said 黄了, that can also mean became yellow, and it is not wrong. But 发黄 often sounds a little more natural when talking about discoloration or a visible change in appearance, especially with things like leaves, paper, teeth, or clothing.
