Embibe Big Book for Science for ICSE Class 9

Science

Ecosystem

This chapter sheds light on the types, components, structure and functions of the ecosystem. It explains food chain, food web, ecological pyramid, and biogeochemical cycle. We will also learn the limitations of ecological pyramids.

In this topic, we will comprise the concept of pond ecosystem in detail. We will understand the details of the pond ecosystem through a labelled diagram. We will study the decomposition of numerous bacteria and fungi as well.

Pond Ecosystem

Via this topic, we will unfold the details of the forest ecosystem in detail. We will enhance our knowledge based on the numerous kinds of flora and fauna present in the forest ecosystem.

Forest Ecosystem: Types and Flora and Fauna

This topic discusses the components of an ecosystem. We will study some examples of biotic and abiotic components.

Components of an Ecosystem

In this topic, we will focus on the content of the food chain in detail. We will also learn about food web and food pyramids through a labelled diagram.

This chapter features the points discussing the categorisation of waste. It also demonstrates the method of safe disposal of waste through diagrams and charts. We will also focus on the method of preparing compost and incineration.

Waste Generation and Management

This chapter covers topics like immunity and immune system, vaccination and immunisation, use and action of medicines, disinfectants and antiseptics, and health organisations.

Aids to Health and Health Organisations

Through this chapter, we will study the main parts related to the respiratory system and their functions. It discusses the difference between respiration and breathing. It explains the mechanism of breathing and some common respiratory diseases.

Respiratory System

This chapter discusses the integumentary system. It explains the structure and functions of the skin. It briefs on the concept of thermoregulation. It also discusses the different skin derivatives.

The Skin

This chapter explains the function of the human skeleton and its constituents. Here, it shows the comparison between male and female skeletons. Joints and its classifications, different types of muscles are also illustrated here.

Movement and Locomotion

Through this chapter, we will understand the functioning of the digestive system. It characterises the significance of various enzymes and organs. It also features certain experimental activities based on the human alimentary canal.

Digestive System

This chapter covers topics like basic food groups and classes of nutrients, and nutritional disorders.

Nutrition

This chapter emphasizes on the morphology and economic importance of bacteria and fungi. We will explore the role of bacteria in medicine, agriculture, and industry. It also discusses the diseases caused by bacteria in plants, animals and humans.

Economic Importance of Bacteria and Fungi

This chapter highlights the features of species and the categories of higher species. It explains the drawbacks of the old kingdom classifications—kingdom Plantae and Animalia. It also discusses the general scheme of five-kingdom classification.

Five Kingdom Classification

In this chapter, we will study the process of respiration. It features the types of respiration in plants and animals through experimental activities and diagrams. Further, we will discuss the relationship between respiration and photosynthesis.

Respiration in Plants

This chapter highlights the classification and characteristics of seeds. It explains the various conditions necessary for germination. Besides, we will study the process of seeding with the aid of examples and diagrams.

Seeds - Structure and Germination

This chapter discusses the process of pollination and fertilisation. It explains the concept of self and cross pollination. It also details the structure of an ovule and events in fertilisation. It further briefs on post-fertilisation events.

Pollination and Fertilisation

This chapter illustrates the structure of bisexual flower through diagrams. Here, it shows the general description of the floral parts—calyx, corolla, androecium, gynoecium. We will also study about inflorescence and placentation with examples.

The Flower

This topic explains the principles of biotechnology. This includes genetic engineering and maintenance of sterility. These two principles are the most widely used in biotechnology.

Biotechnology

This chapter covers topics like introduction to vegetative propagation, natural and artificial methods of vegetative propagation, economic importance of artificial propagation, hybridisation, and micropropagation or tissue culture.

Vegetative Propagation and Micropropagation

This chapter covers topics like introduction to tissues, plant tissues, and animal tissues.

Tissues: Plant and Animal Tissues

This chapter discusses the cell theory. It describes the types, shape, and size of the cells. It explains the cellular structural organisation. It also discusses the plasma membrane, cell organelles, and differentiates between plant and animal cells.

Cell: The Unit of Life

This chapter explains the properties of life and the observable characteristics of living beings. It demonstrates the morphology of living and non-living beings. It also illustrates the comparison of living, non-living, and the dead.

Living, Non-living and the Dead

This chapter covers topics like growth of biology, various branches of biology, and the importance of biology.

Introducing Biology

This chapter discusses topics such as&nbsp;Coronavirus: Structure, Corona Variants, COVID Complications and Prevention &amp; COVID-19 Vaccinations Drive.
