|
Roots/Root Systems |
A below-ground plant organ/organ system that - anchors a plant- stores carbohydrates - absorbs minerals + water |
|
|
Lateral Roots |
Roots that branch off of the primary root that - increase water + mineral absorption - increase anchorage - primarily take on role of absorption in taproot systems |
|
|
Taproots/Taproot Systems |
Root systems in eudicots (majority of flowering plants) that consist of one main vertical root (the taproot) that - prevents the plant from toppling by growing deep (increases anchorage) - are common to tall, top-heavy (large shoots) plants - allow plant to be taller (for more light + pollen/seed dispersal advantages) |
|
|
Fibrous Root Systems |
A thick mat of roots spreading out below soil surface that - helps anchor small short plants that are susceptible to being uprooted by animals - commonly have adventitious roots from the stems - hold top soil in place, preventing soil erosion |
|
|
Adventitious Roots |
Roots that grow from stems or leaves |
|
|
Root Hairs |
Small extensions of roots that grow at the tips of elongating roots that - increase the surface area of roots - increase water + mineral absorption (where absorption primarily takes place) |
|
|
Mycorrhizal Associations |
Symbiotic relationship between plant root systems + soil fungi that increases a plant's ability to absorb minerals |
