Study Notes
Angiosperms in Agriculture
- Angiosperms, also known as flowering plants, make up most of the plants around us.
- They produce seeds inside a fruit, and agriculture is largely dependent on them for food production.
Plant Structure
- Vegetative structures are responsible for the growth and development of the plant, including:
- Leaves
- Stem
- Branches
- Reproductive structures are responsible for producing new plants, including:
- Flowers
- Fruits
- Seeds
Vegetative Propagation
- Under certain conditions, vegetative parts of the plant can be used for reproduction, known as vegetative propagation or asexual reproduction.
- This can be done using:
- Stem
- Leaf
- Roots
Monocotyledon vs Dicotyledon
Monocotyledon
- Examples: Palm tree, grass, sugarcane, rice
- Leaves: Narrow with parallel veins (except plants like dasheen, which has wide leaves and netted veins)
- Flowers: Petals are normally in groups of three (e.g. lily)
- Root: Fibrous root system
Dicotyledon
- Examples: Trees, shrubs, soft-stemmed plants
- Leaves: Wide with a network of veins
- Flowers: Petals are normally in groups of four or five
- Root: Tap root system
