These are the THREE functions a root performs.
Foundation/Anchor the plant, absorb nutrients/water, store food
100
This type of growth is where the root grows longer
What is primary root growth?
100
This type of root has roots growing from the stem. They are common on bulb plants, and do well in dry areas.
What is adventitious roots?
100
These are the TWO ways a stem is protected (old plant and new plant).
What is bark and epidermis?
100
This is the type of wood at the center of the tree that is typically very hard.
What is heartwood?
200
These are similar to blood vessels, and carry water and minerals up to the stem. (hint: it starts with a v)
What is vascular tissues?
200
This type of growth is where the root grows fatter.
What is secondary root growth?
200
These types of roots stick out from the plant and absorb moisture from the air.
What is aerial roots?
200
These are the THREE ways (not tubes) water and nutrients are transported up and down a plant.
What is osmosis, capillarity, and transpiration?
200
These are the cells that develop into xylem and phloem.
What are cambium cells?
300
This protects the tip of the root as it pushes its way through the soil.
What is the root cap?
300
This is the root zone where cells arrange themselves to form the tubes needed to make vascular tissue.
What is the zone of maturation (or differentiation).
300
These roots grow up into the air because they do not receive enough oxygen from the soil.
What is a pneumatophore?
300
This is how diffusion is different from osmosis
What is diffusion of water across a membrane?
300
This is how vascular bundles are arranged in woody dicot stems.
What is in a circular pattern?
400
This is a root system that has a lot of small roots and no central root. Plants with this type of root do very well on steep hills.
What is a fibrous root system?
400
This is the zone of the root where the cells are actively dividing.
What is the zone of cell division?
400
These roots grow close to the roots of other plants and use haustoria to "steal" nutrients from other plants.
What is parasitic roots?
400
This vascular tissue takes water and minerals up and down the plant
What is xylem?
400
This is how vascular bundles are arranged in herbaceous monocot stems.
What is randomly or evenly distributed?
500
This type of root system has a large central root that several smaller roots grow out of.
What is a taproot?
500
This is the zone of the root where the cells themselves become longer.
What is the zone of elongation?
500
These roots grow out from the side of the stem and provide extra support for the plant. They normally do well in areas with wet/soft ground.
What is prop roots?
500
This vascular tissue takes food up and down the plant.
What is phloem?
500
This type of growth habit (or branching) results from more horizontal growth. Most wide, low trees and shrubs grow this way.
What is deliquescent branching?
