Life Processes

Life Processes

      ↓

Nutrition → Respiration → Transportation → Excretion

• Nutrition = taking food • Respiration = release of energy • Excretion = removal of waste

Photosynthesis

Sunlight + CO₂ + Water

          ↓

     Chlorophyll

          ↓

     Glucose + Oxygen

Control and Coordination

Brain

 ↓

Cerebrum – thinking

Cerebellum – balance

Medulla – breathing

Reproduction

• Asexual – one parent • Sexual – two parents

Heredity

• Genes carry traits • Dominant trait appears first

Our Environment

Food Chain

Grass → Deer → Lion

• Only 10% energy is transferred

---

Reflection of Light

• Plane mirror – straight image • Concave mirror – shaving • Convex mirror – vehicles

Refraction of Light

Air → Glass

Light bends

Human Eye

• Myopia – cannot see far • Hypermetropia – cannot see near

Magnetic Effect of Current

• Current produces magnet • Right-hand thumb rule

Domestic Electric Circuit

• Live wire • Neutral wire • Earth wire – safety

---

Chemical Reactions

• Combination • Decomposition • Displacement

Acids, Bases and Salts

• Acid – sour • Base – bitter • pH < 7 = acid • pH > 7 = base

Metals and Non-metals

• Metals – shiny • Non-metals – brittle

Carbon and its Compounds

• Carbon forms four bonds • Diamond, Graphite
