Xylem tubes are made of...

• Dead cells

• Living cells

Which of the following best describes the structure of the phloem?

• The phloem is comprised of many dead sieve cells that have pores in their cell walls to allow movement of substances through the plant.

• The phloem is comprised of many living sieve cells that have pores in their cell walls to allow movement of substances through the plant.

• The phloem is comprised of dead sieve cells that form a long continuous tube.

• The phloem is comprised of living sieve cells that form a long continuous tube.
