Advances in research on phototaxis of insects and the mechanism 昆虫趋光性及其机理的研究进展
2.
Heliotropism a form of phototropism in which flowers move to point toward the sun , tracking it as it moves across the sky 向日性：趋光性的一种类型，植物的花在一天内朝向太阳，并随着日光照射的方向而转移方位。

At this stage the larva looks like a small spider and does not need to seek food from outside sources because it survives on its egg yolk 3 .无节幼虫naplius此期外观如小蜘蛛，此期间靠体内之卵黄维持所需营养不觅求食物，具有很强的趋光性。

On the other hand , the drawing part of the program applies the technology of illumination and texture mapping , taking into account some nature phenomena such as random natural factor and phototropism . the plant , generated by the program , thus is three - dimensional , vivid , and accord with natural law 另一方面，运用光照、纹理映射等技术，结合植物生长过程中的随机因素和趋光性等自然现象，实现了植物生长过程的计算机模拟，生成的植物具有三维立体效果，形态逼真，符合自然生长规律。
