Chloroplasts, minute green, spherical structures, 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.

Photosynthesis, uses atmospheric carbon dioxide and water as building blocks. Organisms that have lost the ability to photosynthesize obtain their carbon indirectly, from plants that are able to

photosynthesize. A by-product of photosynthesis is oxygen, necessary to almost all plants and animals to maintain life. Organisms that breathe in oxygen, exhale carbon dioxide.

IMPORTANCE OF PLANTS .

PLANTS GIVES US OXYGEN GAS.

PLANTS REDUCE CARBONDIOXIDE LEVEL IN ATMOSPHERE.

PLANTS GIVES US FOOD .

PLANTS ARE LIVING OBJECTS.

PLANTS NEED FOOD.

PLANTS MADE THEIR FOOD THEMSELF.

SO PLANTS ARE AUTOTROPH.
