Answer:

Changes in gene expression

Explanation:

This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.

These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.

This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.

non-photosynthetic plants are not common in nature, they do not have a green color, to be able to answer the question we must know that .......

<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>
