__________; their symbiotic relationships still exist today. - Answers - Fungi
*Mastering Biology Chapter 26 practice quiz: What structures allow plants to readily
take up carbon dioxide from the atmosphere? - Answers - Stomata
*Mastering Biology Chapter 26 practice quiz: True or false: Plants have a waxy,
waterproof cuticle, and algae do not. - Answers - True. Algae do not need a waterproof
cuticle because they live in the water.
