CHAPTER TRANSPORT SPM PT.2

What does xylem transport?

• Water and minerals

• Water only

• Sugar

• Food

Without the process of transpiration, a plant would be unable to...

• Move sucrose from the leaves to the roots.

• Create new proteins for the plant.

• Pull up new water and mineral ions from the roots to the leaves.

• Grow towards the light.

After water enters the plant, water travels from the root hair cells, through the ... to the xylem vessels

• phloem

• cortex

• mesophyll cells

• cuticle

How do water enter the roots from the soil?

• diffusion
• osmosis
• transpiration
• active transport

An example of adhesion is

• Water molecules sticking to each other
• Water molecules sticking to cellulose in xylem walls
• Magnets sticking to a metal wall
• Gravity pulling water down

Water movement through cellulose cell wall without entering protoplast of root cells is called

• symplast pathway

• vacuolar pathway

• apoplast pathway

• cellulose pathway

Root pressure is caused by

• active loading of water molecules into xylem vessels by endordermis cells

• active loading of salts into xylem vessels by endodermis cells

• xylem vessels using energy to actively load water upwards

• movement of water molecules upwards in xylem vessels through osmosis

Casparian strip on endodermis cell are made of

• Lignin

• Pectin

• Suberin

• Cellulose

The casparian strip at the endodermis blocks which pathway

• Apoplast

• Symplast

• Transpiration

• Evaporation

How do mineral ions enter a plant?

• by osmosis in root hair cells

• by active transport in root hair cells

• through the stomata

• through the roots
