<h3>It happened in real life</h3>

The newly discovered plant — named <em>Gastrodia kuroshimensis </em>— occurs in the dark understory of forests, where little light penetrates. So instead of using sunlight or photosynthesis to generate nutrients, the plant parasitizes the fungi in the forest soil for its daily dose of nutrition.

With this information we can say that the correct alternative is<u> B</u>. where it states that there are no chloroplasts in the plant cells.

  • B. There are no chloroplasts in the plant's cells.

This may be because of the fact that non-native species can be invasive for the native species. As the species is used as mate by the non-native species and they may become the prey of non-native species. This has resulted in the extinction of the species of Gila trouts.
