Cactus

Cactus are succulents with woody or herbaceous stems that contain chlorophyll. The fleshy stems store water and perform photosynthesis to feed the plant. Unlike other succulents, cactus plants have cushion-like areoles on the surface of the stems. Most cacti have spines. The cacti help in better breathing by purifying the surrounding air. All plants including cacti absorb carbon dioxide and convert it into breathable oxygen. Besides, cacti also clean the toxins from the indoor air, hence helping in upgrading the indoor air quality.
