Photosynthesis: Plants like Muehlenbechia and Opuntia live in dry habitats. They shed their leaves to reduce transpiration.

Their stems become green, possess chloroplasts and are generally flat. Such stems which carry out photosynthesis are called phylloclades. The external morphology is introduced in detail.

The study of the internal structure of plants called anatomy will be introduced for the students so that they can understand the different organized organs and their associated functions in flowering plants.

Different organs of higher plants like root, stem, leaf, inflorescence, flower, fruit and seed, etc.

There are 12 questions in total in the chapter. Chapter Structural Organisation in Animals In this chapter, the large variety of organisms of the Animal kingdom at both multicellular and unicellular level will be discussed for the better understanding. The student will get to know about the organized manner of the animal tissues and their basic functions in both unicellular and multicellular.

The morphology of simple organism and the complex organisms like humans will be discussed.

Students will be surprised to know about the anatomy and functions of tissues which are organized in a manner to form organ system and how these different systems perform various functions like digestive, circulatory, respiratory, nervous and reproductive, etc. A brief account of an insect cockroach will be provided to the students.

There are 14 questions in total.

Chapter 8 - Cell-The Unit of Life In this chapter, students will get to know about the detailed description of the diversified form and appearance of all life forms.
