Ch 1 · How succulents drink and breathe
Fun Fact
Nighttime breathing: Some desert succulents hold their breath all day, only opening their pores at night to prevent water loss.
Glossary
stoma (noun)
A tiny pore in the epidermis of a plant leaf or stem through which gases and water vapor pass. Succulents open these pores primarily at night to absorb carbon dioxide while preventing vital water from evaporating.
