• Taproot sys.

• Fibrous root sys.

• Gymnosperms can have either system

What is the function of the root cap?

• Produce new cells

• Cause elongation

• Absorption of water

• Minimized damage

What structure prevents water from escaping from the vascular tissue in roots?

• Epidermis

• Casparian strip

• Endodermis

• Cortex

What is the function of the root cortex?

• Photosynthesis

• Storage of carbohydrates

• Eudicot or monocot

What direction is water transported in a plant?

• Upwards only

• Downwards only

• Up or down simultaneously

• Direction depends on the context

What direction are sugars transported in a plant?

• Upwards only

• Downwards only

• Up or down simultaneously

• Direction depends on the context

What causes the initial force to move water through the roots?

• Osmotic pressure

• Transpiration

• Active transport of water

• The casparian strip

The main source of upward force bringing water to the top of the plant is
