Roots The root system of a flowering plant begins its development from the hypocotyl of the embryo of the seed which gives rise to the primary root. Roots generally grow downwards into the soil (positively geotropic) and upwards (negatively geotropic). Roots do not bear leaves and therefore no nodes are present.Two kinds of root systems can be distinguished in flowering plants: tap root systems and adventitious root systems. Usually dicotyledons posses tap root systems and monocotyledons adventitious

SKIN AND THE INTEGUMENTARY SYSTEM CHAPTER 6 Your Name () OVERVIEW This chapter describes the skin and its appendages. It explains the structure and function of the layers of skin (dermis and epidermis) and the hair‚ nails‚ and sweat glands. This chapter also explains how the skin helps regulate body temperature and how it responds to environmental factors‚ such as sunlight and injury. Study of the integumentary system is essential to understanding how the body controls interaction between

6. Anatomy of Flowering Plants Tissue It is a group of cells that are similar in structure and are organised together to perform a specific function. It is of two types: Meristematic tissues and Permanent tissues Meristematic tissue It consists of actively dividing cells that are found in those regions of the plant body that show growth. The examples include root tip‚ shoot tip‚ and base of the leaves. It is classified into three types: i. Apical meristem: They are present in

Introduction to Histology Introduction Histology is the microscopic study of cells and tissues of organisms. This study is important in the overall understanding of anatomy and physiology of organisms. It helps to understand the structures and functions of various tissues that make up bodily organs and systems (Wendy Wright‚ 2014). The cell theory states that a cell is the fundamental biological unit. All living organisms are composed of one or more cells‚ and every bodily activity that takes
