What is the main function of the root system in a plant?
- Supporting the stem and bearing leaves
- Conducting photosynthesis and producing flowers
- Anchoring the plant and absorbing water and nutrients (correct)
- Assisting in obtaining sunlight and carbon dioxide

Study Notes
Root System Function
- Anchors the plant in the soil
- Absorbs water and nutrients from soil
- Stores food
Root System Size
- Roots take up more space than the shoot system because they need to reach deeper into the soil
- This allows them to access a wider range of resources, such as water and nutrients
Shoot System Function
- Leaves: Capture sunlight and carbon dioxide for photosynthesis
- Stem: Provides structural support and conducts water and nutrients
- Flowers: Produce seeds for plant reproduction
Monocot vs. Dicot Root Systems
- Monocots: Have a fibrous root system with many small, thin roots that grow shallowly in the soil
- Dicots: Have a taproot system with a single large root that grows deep into the soil
- Taproot system: Provides anchorage and serves as a food storage system
- Fibrous root system: Increases the area available for water and nutrient absorption
