Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Phloem tissue is composed of sieve tubes (sieve tube elements plus companion cells) that transport organic nutrients like sugars. Sieve tubes are the characteristic conducting cells of phloem, arranged end-to-end with perforated sieve plates. Cell tubes is not a standard biological term, sieve cells are found in less advanced plants, and stomata pores are part of leaves, not vascular tissue.
