Bean knowledge: animals can also photosynthesis

Generally speaking, when it comes to photosynthesis, we think of green plants, but in fact, there are animals that can rely on photosynthesis to provide energy for themselves.

there is a situation where animal photosynthesis is pseudo-photosynthesis. For example, corals and sponges are parasitic with Xanthophyta and Chlorophyta, respectively. These algae can help them carry out photosynthesis, which is actually a kind of symbiosis. However, there are some animals that go a step further, directly snatching away the chloroplasts and even genes of algae in order to enable themselves to photosynthesis.

what are the animals here? The answer is green-leaf longicorn beetle (Elysia chlorotica), which is a kind of sea slug. It looks like this:

as early as the late 19th century, it was found that the green-leaf longicorn beetle gradually turned green after feeding on an algae called (Vaucheria litorea). Scientists observed that the chloroplasts of the algae were integrated into their own cells by green-leaf longicorn beetles. And these stolen chloroplasts can help these green-leaf longicorn beetles get energy so that they don't have to eat for N months.

and what's more, recent studies have found that these green-leaf longicorn beetles not only steal chloroplasts, but also leave the genes of algae behind to maintain their continuous photosynthesis.

the feeling is also very strong.

PS: many students may have imagined putting chloroplasts on people's bodies so that they don't have to think about the ultimate problem of what to eat at night. But in fact, this is not easy, because people's surface area is still not large enough relative to their own body size. What if has an issue about this, but it is about the situation of dairy cows.

PPS:. I guess everyone is also concerned about the Nobel Prize in Physiology or Medicine. I am personally very happy that it was awarded to Po's pharmaceutical colleagues, because the research results on antiparasitic drugs are indeed beneficial to mankind.
