• D. Oxygen

Answer 1

Answer: (A), (B), (C)

Carbon dioxide

$\bullet$ Plants prepare their food by a process called photosynthesis.
$\bullet$ Plants require sunlight, carbon dioxide, and water to prepare their food.
$\bullet$ Roots supply water from the ground to all parts of the plant like stem, leaves, etc.
$\bullet$ On the underside of leaves, there are small openings called stomata. It is from here that carbon dioxide enters the plant.
$\bullet$ The leaves contain a green pigment called chlorophyll that absorbs the sunlight and prepares food for the plant using carbon dioxide and water.
