Jonathan Schilling: 作为一名生物科学学院的教授,我认为霉菌种类繁多且颜色各异,在某种程度上,它们是相当美观的。真菌与植物相比,和我们人类的相似度更高。真菌是一个独立的生物界,其中既包括用于制作面包的酵母,也包括可以生长并食用的丝状真菌。丝状真菌专注于快速生长并产生大量孢子,以便在有利的环境中迅速繁殖并扩散到其他地方。这些孢子具有特定的颜色,例如绿色、棕色、黑色,偶尔也会出现粉色和黄色。一旦这些真菌开始生长,它们会尽快产生更多的孢子,这就是它们生长速度如此之快的原因。 Eunice the Unicorn: 作为一个对微生物学充满热情的独角兽,我了解到霉菌是真菌的一种,与蘑菇是近亲。更令人惊奇的是,霉菌孢子中含有黑色素,这与赋予人类皮肤颜色的物质相同。霉菌利用黑色素来保护自己免受阳光照射、极端温度和其他不利环境的影响,就像穿上了一层彩虹色的盔甲。
