记忆方法
可以将“photosynthesis”分解为“photo-”（光）+ “syn-”（一起）+ “thesis”（放置或作用），想象太阳（光）把一些物质（“thesis”意指放置）一起放置或作用，形成光合作用。这种方法通过拆解词根和词缀来帮助记忆整个单词的含义。

英语词源
- photosynthesis (n.)
- 1898, loan-translation of German Photosynthese, from photo- "light" (see photo-) + synthese "synthesis" (see synthesis). Another early word for it was photosyntax.
[T]he body of the work has been rendered into English with fidelity, the only change of moment being the substitution of the word "photosynthesis" for that of "assimilation." This change follows from a suggestion by Dr. Barnes, made a year ago before the American Association at Madison, who clearly pointed out the need of a distinctive term for the synthetical process in plants, brought about by protoplasm in the presence of chlorophyll and light. He proposed the word "photosyntax," which met with favor. In the discussion Professor MacMillan suggested the word "photosynthesis," as etymologically more satisfactory and accurate, a claim which Dr. Barnes showed could not be maintained. The suggestion of Dr. Barnes not only received tacit acceptance by the botanists of the association, but was practically approved by the Madison Congress in the course of a discussion upon this point. ["The Botanical Gazette," vol. XIX, 1894]
