Energy from sunlight can excite electrons, kicking them out of their orbitals and creating freeradicals. Free radicals are highl
y reactive atoms or molecules that have unpaired electrons and degrade and destroy other compounds in their vicinity. Carotenoids, one of the pigments present in most chloroplasts, can stabilize these free radicals. This suggests that _____. A) once chloroplasts are destroyed, the free radicals will destroy the cell
B) carotenoids probably have a protective function in the cell
C) free radicals induce the synthesis of carotenoids in chloroplasts
D) carotenoids communicate directly with the immune system of plants
Carotenoids are red, yellow or orange shades pigments by numerous plants, parasites, and microscopic organisms.
In plants, carotenoids are found in roots, stems, leaves, blooms, and natural products. Inside a plant cell, carotenoids occur in the films of plastids, organelles encompassed by trademark twofold membranes.
Carotenoids performs the function of protecting chlorophyll from photo-damage by making the free radicals stabilized.
Sun is classified as a G2 V star, with G2 standing for the second hottest stars of the yellow G class of surface temperature about 5,800 kelvins (K) and the V representing a main sequence, or dwarf, star, the typical star for this temperature class.
