Transcript of Roots

Types of Roots
Uptake of Plant Nutrients
Soil- complex mixture of sand, silt, clay, air, decaying plant/animal matter
Soil determines what types of plants can grow in it.
Nutrients- nitrogen, phosphorus, potassium, magnesium, calcium
Trace elements- sulfur, iron, zinc, molybdenum, boron, copper, manganese, chlorine
Active Transport of Minerals
Active transport proteins
in root hairs and root epidermis
use ATP to pump mineral ions from soil into plant
high concentration of mineral ions causes osmosis
root does not pump water but causes water to be attracted to the ions
Root Pressure
Casparian strip helps create root pressure
water in xylem is forced upward against gravity
Movement into Vascular Cylinder
water and minerals flow from epidermis -> cortex -> endodermis -> Casparian strip -> Vascular cylinder -> xylem
Casparian strip- in between walls of endodermis, waterproof, prevents backflow of water
found in dicots
large primary root with smaller secondary roots
oak and hickory trees can reach water below earth's surface
fibrous roots
found in monocots
branch so that no root is dominant over the rest
prevent topsoil from being washed away by heavy rain
