ICSE Biology Class 7 Syllabus

The syllabus consists of five themes - (i) Tissue, (ii) Kingdom Classification, (iii) Plant Life, (iv) Human Body, and (v) Health and Hygiene.

Theme 1: Tissue

Plant Tissues

  • Definition of tissue.
  • Classification of plant tissues: Meristematic and permanent (simple and complex).
  • Meristematic tissues: characteristics (any two), simple structure, location, function, examples.
  • Simple permanent tissues: parenchyma, collenchyma, sclerenchyma (simple structure, location and functions of each), examples.
  • Complex permanent tissues: xylem, phloem (only nature of cells and function. Elements of xylem and phloem not to be mentioned).

Animal Tissues

  • Epithelial tissue: simple location, and function (types of epithelial tissue not to be mentioned).
  • Connective tissue location and functions of areolar, adipose, bone, cartilage, blood, ligament, tendon.
  • Muscular tissue: location and one function of:
    • striated (voluntary or skeletal muscle),
    • unstriated (involuntary/ smooth muscle),
    • cardiac (specialized muscle).
  • Nerve tissue: parts of neuron (cell body, Dendron, axon).

Theme 2: Kingdom Classification

  • Meaning and concept of classification.
  • Need and advantages of Classification.

Characteristics of each kingdom with suitable examples:

  1. Monera: bacteria - shape; useful bacteria, harmful bacteria (applications related to daily life to be discussed);
  2. Protista: Amoeba - basic structure and life processes (nutrition, locomotion, respiration, excretion and reproduction - by binary and multiple fission);
  3. Fungi: basic structure of mould, nutrition and respiration in mould, useful fungi, harmful fungi (applications related to daily life to be discussed);
  4. Plantae: characteristics and examples (classification of plantae not to be discussed);
  5. Animalia
    1. Vertebrates.
    2. Invertebrates: 9 major Phyla, Porifera, Cnidaria, Coelenterata, Platyhelminthes, nematoda, Annelida, Arthropoda, Mollusca, Echinodermata) (Two characteristics and two examples of each Phylum).

Theme 3: Plant Life

Photosynthesis

  • Definition, basic process, factors affecting photosynthesis: (light, carbon dioxide, water, chlorophyll), significance of photosynthesis, setup.
  • Experiment to demonstrate photosynthesis process.

Respiration

  • Basic process, word equation; respiration as a process which releases energy; respiration in plants: two types (aerobic and anaerobic: basic concept, word equations for both,
    examples).
  • Respiration and photosynthesis in plants, difference in both processes.

Theme 4: Human Body

Excretory System

  • Excretion: Definition.
  • Organs and their excretory products (kidneys, sweat glands, lungs);
  • Renal Excretory System - kidneys, ureter, urinary bladder, urethra (location and functions to be explained along with diagram);
  • Role of kidneys infiltration of blood through millions of nephrons (details not required, structure of nephron not to be discussed);
  • Common disorders of the urinary system: Urinary Tract Infection, kidney stone.

Nervous System

  • Main parts: brain, spinal cord, nerves.
  • Brain: cerebrum, cerebellum, medulla oblongata (location and function).
  • Spinal cord: location and function.
  • Nerves: what are nerves; their general function.

Theme 5: Health and Hygiene

Allergy

  • Concept of allergy.
  • Allergens: Common allergens like dust, pollen grain, mites, strong sunlight, particular food items.
  • Entry routes of allergens: mouth, nose, skin.
  • Symptoms of allergic reaction.
  • Types of allergies: seasonal and perennial with examples.
  • Precautions and care to be taken by a person who is prone to allergies.
