Question

Chlamydomonas nivalis colors the snow
 A .Red
 B. Yellow
 C .Green
 D.Purple brown

Answer 1

Hint: This unicellular life form is an individual from the assorted green growth Division Chlorophyta (Order Volvocales), and contains a brilliant red carotenoid color notwithstanding chlorophyll. In contrast to most types of new water green growth, it is cryophilic (cold-adoring) and flourishes in freezing water.

Complete answer:
Chlamydomonas nivalis is a unicellular red-shaded photosynthetic green alga that is found in the snowfields of the alps and polar areas everywhere on the world. They are one of the principle green growth answerable for causing the wonder of watermelon day off; patches of snow seem red or pink.

Additional Information: In the high mountain scopes of the western United States, at any rate, 60 unique types of snow green growth have been recognized, yet a couple of sorts have been accounted for from the Sierra Nevada. One of the most well-known types of snow green growth in California, and the one answerable for a pink day off, Chlamydomonas nivalis. Its logical family name, nivalis, is from Latin and alludes to day off. During pre-summer and summer, elevated snowbanks are regularly hued wonderful shades of red by a heap of algal cells. The focuses or "sprouts" may stretch out to a profundity of 25 centimeters (10 inches). Each round cell is around 30 micrometers in width, around multiple times the breadth of a human red platelet. It has been assessed that one teaspoon of dissolved snow may contain in excess of 1,000,000 cells of snow green growth.
So the correct answer is red.

Note: Compacting the snow expands the thickness of the red cells and elevates the shading. In some cases, the green growth aggregate in shallow miseries in the snow called sun cups. Since the dim red color retains heat, the cells liquefy their way into the day off, extending the sun cups and quickening the softening pace of snow banks and icy masses. Snow green growth is not generally limited to locales of the never-ending day off, in the high piles of southern California where there is a finished dissolving of snow each midyear.
