Question
Chapter 28.1, Problem 3CC
Summary Introduction
To explain:
The role of central vacuoles and cellulose cell wall in plant growth.
Introduction:
A plant cell contains a cell wall, chloroplast and one large central vacuole. Central vacuole store water, sugars, ions amino acids and wastes in a cell. Central vacuole helps the plant cells to from mechanical damage.
