Study Notes

Parts of Plant Body and Their Functions

Each part of a plant serves specific roles, similar to human body parts.
Growth, self-protection, and reproduction are primary functions of plant body parts.

Roots

Essential part of the plant responsible for several functions:
- Absorbs water and nutrients from the soil.
- Anchors the plant securely in place.
- Assists in respiration for plant growth.
- Stores food reserves.
Examples of plants storing food in roots: carrot, sweet potato, radish, potato, cassava.

Types of Roots Based on Shape

Taproots: Main root that grows downwards, with smaller branches. Examples include cassava, banyan, and durian.
Fibrous roots: Grows from the base of the stem in clusters, substituting for taproots. Examples are rice, corn, snake fruit, ginger, banana.

Types of Roots Based on Function

Hanging roots: Absorb moisture from the air. Example is fig tree.
Breathing roots: Emerge above the soil for respiration and salt secretion. Examples include mangrove trees.
Stilt or prop roots: Provide support to prevent falling. Common in pandanus and kenari trees.

Flowers

Incomplete flowers have either stamens or pistils but not both. Examples include coconut, snake fruit, oil palm, corn, and sugar palm.
Functions of flowers include decoration for events and religious ceremonies.

Fruits

Fruits develop from flowering plants and serve as protection for seeds and as a base for new plants.

Types of Seeds

Monocotyledon (single seed leaf):
- Fibrous root system.
- Parallel leaf venation.
- Lacks cambium, limited secondary growth.
- Examples: corn, rice, coconut, and shallots.
Dicotyledon (two seed leaves):
- Taproot system.
- Net-like leaf venation.
- Contains cambium for secondary growth.
- Examples: mango, rambutan, durian, orange, guava, and papaya.

Photosynthesis

Plants perform photosynthesis primarily in leaves, using sunlight as energy.
The process involves water absorption and mineral intake through roots.
Chlorophyll in leaves aids in capturing sunlight.
Common sources of energy for photosynthesis include sunlight.
Photosynthesis is vital for plant growth and oxygen production.

Plant Function and Learning Goals

Understanding plant parts and their respective functions is crucial.
Students will learn to identify parts and understand their roles in growth and survival.

Learning Approach and Reflection

Engage with the environment and material through observation and questions.
Summarize and evaluate the learning process with reflection and planning for future lessons.
