ICSE Class 7 Biology Books – Chapters, Practice & PDFs

This page lists the ICSE Class 7 Biology books chapter by chapter. It covers 8 chapters of the Class 7 Biology textbook Biology, and each listed chapter has its PDF on this page.

The PDFs give you the text, but not the shape of each chapter. For every chapter this page counts its named sections, its practice questions and its page count — all read from the book itself. A revision order further down tells you which chapter to open first and where the heavy practice sits.

ICSE Class 7 Biology Books: what is inside each chapter

The directory counts what the book actually shows. A section is one of the book’s own main headings — sub-headings are not counted. A practice question is a numbered item under an exercise heading. Pages are the chapter’s pages in the PDF.

Chapter 1: Cell the Structural and Functional Unit of Life (Biology)

The cell is where living structure begins. The chapter covers why cells matter as a basic study in biology, how numerous and how small they are, and the shapes cells take. It works through the three essential parts of a cell and the finer structure — the organelles. A microscope examination of onion peel and the nucleus as the key to a cell’s life are both covered here.

• 1.1 Cells – a Basic Study in Biology
• 1.2 Cells – How Numerous?
• 1.3 Cells — How Small?
• 1.4 Cell Shapes
• 1.5 Gross Structure of Cell – the Three Essential Parts
• 1.0 Finer Structure of Cell – the Organelles

Chapter 2: Organisation in Living Things (Biology)

Organisation builds upward, from single tissues to whole systems. The chapter works through the plant tissues — parenchyma, collenchyma and sclerenchyma — then the conducting tissues xylem and phloem. Animal tissues come next: epithelial, connective, muscular and nervous, with striated muscle and nerve cell as named examples. The skeletal system and the muscular system show the next level of organisation.

• Parenchyma
• Collenchyma
• Sclerenchyma
• Xylem
• Phloem
• Epithelial Tissue (Fig. 2.10)

Practice sits in the Review Questions exercise, which sets 13 questions.

Chapter 3: Movement in Animals and Plants (Biology)

Movement is traced from single cells to humans and plants. The chapter covers movement in microscopic organisms, creeping movement in Amoeba, crawling movements, and the floating, swimming and leaping movements of the frog. Swimming in fish and flying movements in birds, insects and bats come next. Human movement takes in the skeleton, the axial and appendicular parts, joints from immovable to movable, and the coordination of muscles — with tropic and nastic movements in plants covered as well.

• Movement in Animals and Plants
• Movements in Microscopic Organisms
• Creeping Movement (as in Amoeba)
• Can You Recollect ?
• Crawling Movements
• Floating, Swimming and Leaping Movements (in Frog)

and 39 more

The Short Answer Questions exercise sets 18 questions, and the figure-tagged joint sections read best beside the PDF’s own figures.

Chapter 4: Nutrition in Animals and Plants (Biology)

Food is where this chapter begins — the primary need for life. It sets out the types of nutrients and classifies food into energy-giving, body-building and protective foods, then covers vitamins, minerals, water and roughage. Food groups, a balanced diet, calorie requirements, food fads and food additives come next.

Plant nutrition follows — photosynthesis, the working of the stomata and the factors affecting it — along with the nutrient elements of plants and the types of nutrition: holozoic, parasitic, saprophytic, symbionts and food webs.

• Nutrition in Animals and Plants
• [The Primary Need for Life]
• Food for Life
• The food provides our body
• Nutrition
• Types of Nutrients

and 35 more

The Short Answer Questions exercise gives you 25 questions to work through.

Chapter 5: Ingestion Digestion Absorption and Assimilation in Humans (Biology)

Follow food through the human body and you have this chapter’s route. It starts at the mouth with teeth — their types and structure — then the tongue and taste buds, the salivary glands and the functions of saliva. The oesophagus and the stomach come next, then the small intestine and how digested food is absorbed there. The large intestine and the assimilation of digested food are also covered.

• Ingestion, Digestion, Absorption and Assimilation in Humans
• Digestive System in Humans
• The Mouth
• Types of Teeth
• The Human Teeth
• Structure of a Tooth (Fig. 5.3)

and 11 more

Practice here is the Short Answer Questions exercise, a set of 25 questions.

Chapter 7: Excretion in Animals and Plants (Biology)

Removing waste is the thread that runs through this chapter. It defines excretion and lists the substances to be excreted, then works through the urinary system and how the bladder empties. The structure of the kidney, the formation of urine in the nephron and the composition of urine follow. Osmoregulation, what happens if kidneys fail, and excretion in plants are also covered.

• Excretion in Animals and Plants
• What IS Excretion ?
• Substances to be Excreted
• The Urinary System
• How the Bladder Empties
• Structure of the Kidney

and 6 more

The chapter’s Short Answer Questions exercise sets 16 questions.

Chapter 8: Increasing Population Its Impact on the Environment (Biology)

This short chapter stays on one topic: the growth of India’s population. It covers the trends of population growth in India, the factors responsible for that growth, and the problems that follow from population explosion.

• Trends of Population Growth in India
• Factors Responsible for Population Growth in India
• Problems Due to Population Explosion

Practice for this chapter is the Short Answer Questions exercise, which has 14 questions.

Chapter 9: Life Under a Microscope (Biology)

Life gets very small in this chapter — microscope small. It looks at the life processes of microscopic organisms: nutrition, respiration and reproduction. Harmful bacteria come next, then a series of named microscopic algae — Chlorella, Chlamydomonas, desmids, diatoms, Spirogyra and Volvox.

• Nutrition
• Respiration
• Reproduction
• Harmful Bacteria
• Chlorella
• Chlamydomonas (Fig. 9.5)

How to revise Class 7 Biology chapter by chapter

Work in the order the ideas build:

1. Chapter 1, Cell the Structural and Functional Unit of Life — the foundation every later chapter assumes.
2. Chapter 2, Organisation in Living Things — connects cells to tissues to systems.
3. Chapter 4, Nutrition in Animals and Plants — food, diet and photosynthesis.
4. Chapter 5, Ingestion, Digestion, Absorption and Assimilation in Humans — follows food through the digestive tract.
5. Chapter 7, Excretion in Animals and Plants — what the body must remove.
6. Chapter 3, Movement in Animals and Plants — the heaviest chapter on this page at 45 sections, covering the skeleton and joints; take it after the body systems are clear.
7. Chapter 8, Increasing Population Its Impact on the Environment — the shortest chapter, 7 pages.
8. Chapter 9, Life Under a Microscope — reuses the cell ideas from Chapter 1.

One gap to note: Chapter 6, Respiration and Transpiration, sits between Chapter 5 and Chapter 7 in the book’s numbering but is not on this page yet. If your teacher follows the book’s order, read it from the school textbook.

Practice loads are uneven. Chapters 4 and 5 each set 25 short answer questions — the most on this page — while Chapter 3 sets 18, Chapters 7 and 9 set 16 each, Chapter 8 sets 14 and Chapter 2’s Review Questions set 13.

One homework question and no time? Jump by topic:

• Teeth, saliva, digestion — Chapter 5.
• Nephron, urine, the kidney — Chapter 7.
• Skeleton, joints and muscle movement — Chapter 3.
• Photosynthesis and stomata — Chapter 4.
• Onion peel and the cell — Chapter 1.

Sources and data verification

The counts on this page describe the Class 7 Biology textbook named in every row of the directory: Biology.

Every count was read from the book itself — its section headings and exercise lists — and can be checked against the chapter’s PDF on this page.

This page covers 8 of the book’s 9 chapters. The chapter it does not yet cover is:

• Biology: chapter 6, Respiration and Transpiration, is not on this page yet. In the book’s numbering it sits between Chapter 5 and Chapter 7.
