n.趋光性

Phototaxis is a behavior observed in many organisms, where they move towards or away from light sources.
光趋性是在许多生物体中观察到的一种行为，它们会向光源移动或远离光源。
In the case of Euglena, a type of single-celled organism, phototaxis allows it to move towards a light source for photosynthesis.
对于眼虫（一种单细胞生物）来说，光趋性使其能够向光源移动以进行光合作用。
Some species of bacteria exhibit negative phototaxis, moving away from light to avoid overheating or photodamage.
有些细菌表现出负光趋性，远离光源移动以避免过热或光损伤。
The larvae of some insects, such as the tobacco hornworm, exhibit positive phototaxis and move towards light to find food plants.
某些昆虫的幼虫（如烟草角蛾）表现出正光趋性，并向光源移动寻找食物植物。
In marine environments, phytoplankton often exhibit phototaxis to optimize their position in the water column for photosynthesis.
在海洋环境中，浮游植物经常表现出光趋性，以优化其在水柱中的位置，以便进行光合作用。
Some animals use phototaxis to navigate their environment, such as moths flying towards moonlight during migration.
一些动物利用光趋性来导航其环境，例如飞蛾在迁徙过程中飞向月光。
In controlled experiments, researchers can manipulate light sources to study how organisms respond to different intensities and wavelengths of light.
在受控实验中，研究人员可以操纵光源，研究生物体如何对不同强度和波长的光线做出反应。
Phototaxis is not only observed in aquatic or terrestrial organisms but also in certain fungi that grow towards light for spore dispersal.
不仅在水生或陆地生物体中观察到光趋性，某些真菌也向光源生长以利于孢子传播。
The study of phototaxis has implications for understanding the evolution of sensory systems in organisms across different habitats.
研究光趋性对于理解不同栖息地中生物感官系统的进化具有重要意义。
Artificial light pollution can disrupt the natural phototactic behaviors of some species, leading to negative impacts on their survival and reproduction.
人工光污染会干扰某些物种的自然光趋性行为，对其生存和繁殖产生负面影响。
