1·Protozoa are unicellular microorganisms that feed on bacteria, and sometimes the bacteria survive and replicate within the protozoa, the study claims.
原生生物是靠不是细菌为生单细胞微生物，但是研究声称有时候细菌可以存活下来并且反噬原生生物。
2·By searching for genetic sequences similar to regA in the burgeoning databases of genes that now exist, they found one in a unicellular alga called Chlamydomonas reinhardtii.
他们在现有的尚处于萌芽阶段的基因数据库中搜索与regA的基因序列相似的基因，并找到了一种属于单细胞藻类Chlamydomonas reinhardtii的基因。
3·Think again. This unicellular diatom (diatom Arachnoidiscus), a type of algae, reveals an intricate rainbow pattern under 40x magnification.
再想想，这种单细胞的硅藻(网状硅藻属的硅藻)，是一种类型的海藻，放大了40倍后，显示了像“彩虹”那样的错综复杂五彩缤纷排列。
4·Geometric structures in two and three dimensions abound in the natural world, from complex crystal shapes to starfish, and unicellular organisms like diatoms.
在二维和三维的几何结构有大量的自然世界，从复杂的晶体形状海星，硅藻的单细胞有机体，像。
5·We cannot be certain that Gonium, pandonina, Eudonna, and Pleodorina represent stages in the evolution of multicellular Volvox from unicellular chlamydomonas.
我们不能肯定盘藻、实球藻、空球藻和杂球藻代表从单细胞衣藻到多细胞因藻的各进化阶段。
