A Deep Thinking

And He it is Who sends down water from the cloud, then
We bring forth with it buds of all (plants), then We bring forth from it green
(foliage) from which We produce grain piled up (in the ear); and of the
palm-tree, of the sheaths of it, come forth clusters (of dates) within reach,
and gardens of grapes and olives and pomegranates, alike and unlike; behold the
fruit of it when it yields the fruit and the ripening of it; most surely there
are signs in this for a people who believe. [6-99]

The green factory in plants

This Ayat of Quran tells us that there is a ‘green’ factory in the
plants which produces grains. Green factories are built up by the plant at the
beginning of its growth and are called by botanists “Chloroplasts” which contain
the chlorophyll. Quran uses the term خضرا
for these green factories. Chlorophyll absorbs the light necessary for
photosynthesis.

Chloroplasts

An
examination of leaves, stems, and other types of plant tissue reveals the
presence of tiny green, spherical structures called chloroplasts, visible here
in the cells of an onion root. Chloroplasts are essential to the process of
photosynthesis, in which captured sunlight is combined with water and carbon
dioxide in the presence of the chlorophyll molecule to produce oxygen and sugars
that can be used by animals. Without the process of photosynthesis, the
atmosphere would not contain enough oxygen to support animal
life.

It is amazing that Quran mentions the chloroplasts and
chlorophylls which were discovered many centuries after the revelation of
Quran.
