Plasma Membrane

This chapter covers the phenomenon exhibited by the plasma membrane. It explains the process of plasma getting in and going out, along with a brief on osmosis and filtration. It also discusses the functions of the plasma membrane.

This topic will concentrate on the characteristics of the plasma membrane. It also elaborates the classification and features based on some lab activities. Different figures and examples are also provided here.

Characteristics of Plasma Membrane and Experiments Related to It

With the aid of this topic, we will be able to focus on the functions of the plasma membrane. It also demonstrates some facts based on endocytosis and osmosis. Furthermore, it details its specialization.

Functions of Plasma Membrane

This topic demonstrates the vision of membrane transportation of solute and solvent. It also explains the process of permeability and semi-permeability. Furthermore, it contains experimental activities and facts for illustration.

Transport Across the Membrane

Through this topic, we will learn about osmosis and osmotic pressure. It also elucidates its importance with its characteristics. Besides, it will focus on the concept of diffusion with the aid of activities and examples.

This chapter explains that the biogeochemical cycle involves both biotic and abiotic components. We will study the significance of their interdependent nature. Moreover, it demonstrates the transfer of matter and energy.

Biogeochemical Cycles

This chapter discusses the process of soil formation and the properties and fertility of the soil. It covers the causes of land pollution along with a brief note on biomagnification and deforestation. It briefs on the pollution of underground soil.

Soil Pollution

This chapter focuses on the flow of ecosystem comprising different habitats. It also discusses the method of adaptation according to climate and circumstances with the aid of examples and pictures.

Adaptations in Different Ecosystems

The chapter discusses the numerous challenges faced in improving agricultural products. It also determines the ratio of food production and the growth of the population. Furthermore, it involves activities for illustrating these concepts.

Challenges in Improving Agricultural Products

This chapter distinguishes animal behaviour from human behaviour. It details the types of animal behaviour, including instinct, imprinting, conditioning and imitation. It also explains the methods of investigating the behaviour.

Animal Behaviour

In this chapter, we will have a detailed study of the sense organs, including ears, eyes, tongue, mouth and skin. It also explains the process of stimulation to sensation. Functions and responses of each sense organ are discussed here.

Sense Organs

This chapter discusses the basis of classification of organisms, classification and evolution of organisms, the hierarchy of classification, Plantae kingdom, Animalia kingdom and nomenclature.

Diversity in Living Organisms

In this chapter, we will study the animal tissues in detail. It elaborates on the classification of animal tissues. The characteristics of epithelial, muscular, nervous and connective tissues are also discussed here.

Animal Tissues

This chapter describes different types of plants and their tissue functions. It describes the meristematic and permanent tissues found in plants. Further, the classification of these tissues is also discussed here with the aid of pictures.

Plant Tissues

This chapter covers the description of the cell and its morphological structure. It also summarises its discovery. Furthermore, it comprises a pictorial representation of cells and activities for illustration.
