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>

A loopful of bacteria containing 1000 bacterial cells is inoculated into a nutrient broth and incubated. After a negligible lag
Black_prince [1.1K]

Answer:

<h2>a.  1000 X 2^8</h2>

Explanation:

As given;

Initial population of bacteria= 1000;

Log phase growth is exponential phase, period in which bacteria gets double.

Generation time= 15 minutes;

it means, bacteria get double in every 15 minute,

so after 2 hours, bacteria will have 8 generation times;

so the final generation of bacteria is =1000 X 2^8.

Final bacterial generation after two hours = 256,000(1000 X 2^8)
