Study Notes
Root System Functions
- The main function of root hairs is to increase the surface area of the root, allowing for more efficient water and nutrient uptake.
Types of Roots
- Taproots have a main root with branching roots off of it.
Importance of Water Uptake
- Water uptake is necessary for plants to carry out photosynthesis, maintain turgor pressure, and transport nutrients and sugars.
Essential Nutrients
- Potassium is important for promoting flowering and fruiting in plants.
Tubercular Roots
- The main function of tubercular roots is to store food and nutrients.
Characteristics of Root Hairs
- Root hairs are characteristic of being long, thin extensions of the root epidermal cells that increase the surface area of the root.
