Their study involved a group of proteins called cadherins, which help your cells stick together.

But others, the chloroplasts, which are the organelles inside of a plant cellthat allows plants to photosynthesize, the slugs take those and stick them inside of their own cells, and then they become photosynthetic.

是其他的， 叶绿体，它是植物细胞内的细胞器， 可以让植物进行光合作用，海参吸收这些细胞器并将它们粘在自己的细胞内，然后它们就进行光合作用。
