Question
Chapter 38, Problem 9TY
Summary Introduction
Introduction: The guard cells are parenchymatous cells that are kidney bean-shaped and help to regulate the opening and closing of the stomata. The two guard cells are required to make one stoma. The plant leaf consists of abundant of stomata that help the plant in gaseous exchange.
