Xylem and Phloem Quiz

What is the primary function of the xylem in plants?

• Absorbing nutrients from the soil

• Producing glucose during photosynthesis

• Transporting sugars from leaves to roots

• Transporting water from roots to leaves

What process allows water to be absorbed into the plant via the roots?

• Osmosis

• Translocation

• Photosynthesis

• Transpiration

What type of cells make up the xylem?

• Dead hollow cells

• Dead cells with thick walls

• Living cells with thick walls

• Living cells with thin walls

What substance strengthens the cell walls of xylem cells?

• Chlorophyll

• Cellulose

• Lignin

• Sucrose

What is the primary function of the phloem in plants?

• Transporting water from roots to leaves

• Transporting sugars as sucrose

• Absorbing nutrients from the soil

• Producing glucose during photosynthesis

What are sieve plates in the phloem?

• Structures that absorb water

• Structures that separate compartments of the phloem

• Structures that produce glucose

• Structures that strengthen the phloem

What process describes the movement of sugar around the plant?

• Transpiration

• Osmosis

• Photosynthesis

• Translocation

In which direction does transpiration occur?

• Up and down the plant

• From roots to leaves

• From leaves to roots

• In all directions

In which direction does translocation occur?

• In all directions

• Bi-directionally up and down the phloem

• Only from leaves to roots

• Only from roots to leaves

What is the difference between transpiration and translocation?

• Both move sugars in two directions

• Transpiration moves water; translocation moves sugars

• Transpiration moves sugars; translocation moves water

• Both move water in one direction
