Energy from sunlight can excite electrons, kicking them out of their orbitals and creating freeradicals. free radicals are highly 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

Option B

Explanation:

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.

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
