Question
Chapter 33.3, Problem 2R
Summary Introduction
To review:
The different primary meristems present in plants and the mechanism by, which they give, rise to the various tissues and the organs.
Introduction:
The primary meristems are regions composed of a mass of undifferentiated cells, which are capable of differentiating into all the tissues and organs that make up the body of a plant. They are responsible for the primary growth, which determines the basic structure of the plant.

- Explain what a meristem is, and describe its role in plant growth.arrow_forwardA plant stem's two main functions are to support the leaves and to transport materials between roots and leaves. As a stem develops, it possesses three types of permanent tissues: surface tissue, ground tissue, and vascular tissue. The surface and ground tissues support and give structure to the plant. The vascular tissues are the transport systems of the plant. The vascular tissues usually exist in one of three patterns and are known as the phloem and xylem. Both the xylem and phloem are made up of several different types of cells that make up transport tubes for needed nutrients. In general, xylem nutrients (sap) travel from the roots to the rest of the plant. Phloem sap is derived from photosynthesizing leaves and from there is carried throughout the plant. 24.
