<h3>General characteristics of plants</h3>

Plants are classified as autotrophic organisms, since the large one is capable of photosynthesis. With the exception of plants, some achlor species being observed, therefore, not achlorizing plants.

<h3>Chloroplast</h3>

Chloroplast, a structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.

<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.

<u>These </u><u>plants</u><u> that do </u><u>not photosynthesize</u><u> do not have the green </u><u>pigment</u><u>, what gives the </u><u>plants</u><u> their </u><u>green color</u><u> is the </u><u>chlorophyll</u><u> that is in the </u><u>chloroplast.</u>
