Listen to part of a lecture in an environmental science class.
請聽環境科學課上的部分內容。
When you try to imagine a fungus, you’d probably picture a mushroom popping up out of the ground and think that’s it.
當你們試著想象真菌的時候，你們可能會想到蘑菇冒出地面的場景，并且認為就只是這樣了。
But a fungus like that...most of it actually lives underground, and fungi in general are often an important active component of the soil.
但是像那樣的真菌......實際上大部分的真菌都生活在地下，而且菌類通常是土壤中重要的活躍成分。
A fungus secretes enzymes into the soil, enzymes that break down, decompose organic material in the soil. So the fungus can absorb this material and get nutrition.
真菌會把酶分泌進土壤中，酶會分解土壤中的有機材料，這樣真菌就能吸收這種材料得到養分了。
But to me, what’s most interesting about this process is how it may enable fungi to help clean up environmental pollution in the soil.
但是這個過程對我來說最有趣的部分是它能夠幫助清理土壤中的環境污染。
And that’s thanks in part to a substance in their cell walls called chitin.
而這某種程度上要感謝它們細胞壁中一種叫做角素的物質。
Now a lot of people think fungi are related to plants, but they are not.
很多人認為菌群和植物有關，但其實不是。
Believe it or not, the only other place chitin is found in abundance is in the exoskeletons of insects, crabs and such.
信不信由你，唯一能發現豐富的角素的其他地方只有昆蟲、螃蟹之類的外骨骼中。
So in this sense, fungi are more associated with insects than with any plant. Strange, uh?
就這種意義而言，真菌和昆蟲的聯系比和任何植物還要緊密，很奇怪，對吧？
