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
- 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).
- 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:
- Monera: bacteria - shape; useful bacteria, harmful bacteria (applications related to daily life to be discussed);
- Protista: Amoeba - basic structure and life processes (nutrition, locomotion, respiration, excretion and reproduction - by binary and multiple fission);
- Fungi: basic structure of mould, nutrition and respiration in mould, useful fungi, harmful fungi (applications related to daily life to be discussed);
- Plantae: characteristics and examples (classification of plantae not to be discussed);
- 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
- Definition, basic process, factors affecting photosynthesis: (light, carbon dioxide, water, chlorophyll), significance of photosynthesis, setup.
- Experiment to demonstrate photosynthesis process.
- 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,
- Respiration and photosynthesis in plants, difference in both processes.
Theme 4: Human Body
- 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.
- 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
- 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.
