Question

70 Plants give out oxygen gas during a process ……….

Answer 1

Plants give out oxygen gas during the process of photosynthesis.

• The process in which Carbon dioxide and water in the presence of sunlight and chlorophyll release Glucose and Oxygen. Through this process, plants prepare their own food.
• Plants that released Oxygen during this process are consumed by human beings.

$\underset{\mathrm{Carbon}\mathrm{Dioxide}}{6{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Water}}{6{\mathrm{H}}_2\mathrm{O}}\left(\mathrm{l}\right)\underset{\mathrm{Chlorophyll}}{\overset{\mathrm{sunlight}}{\to }}\underset{\mathrm{Glucose}}{{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6}\left(\mathrm{aq}\right)+\underset{\mathrm{Oxygen}}{6{\mathrm{O}}_2}\left(\mathrm{g}\right)$

Therefore, Plants give out oxygen gas during the process of photosynthesis.
