Chapter 39, Problem 10TY
Summary Introduction
Introduction: Phloem of flowering plants is made up of sieve elements. These elements are arranged in plants in the form of transport pipes. A combination of sieve elements and companion cells helps in the transfer of organic substances made during photosynthesis within the cells of the plant.
