Question

in the alternating generations of the plant life cycle, the haploid plant body is called the select answer. the diploid plant body that makes up the other half of the plant life cycle is called the select answer.

in vascular plants, which of the following is the vascular tissue that distributes water and dissolved mineral ions?
lignin
xylem

Explanation:

Identify plant life cycle stages

Using the Alternation of Generations and Sporophyte and Gametophyte knowledge points, we identify the multicellular phases. The haploid (\(n\)) multicellular plant body is the gametophyte, which produces gametes. The diploid (\(2n\)) multicellular plant body is the sporophyte, which produces spores.

Identify vascular transport tissue

We analyze the tissue responsible for water transport. Vascular plants utilize specialized conductive tissues. Xylem distributes water and dissolved mineral ions upward from roots, while phloem transports organic nutrients like sugars. Lignin is a structural polymer, not a transport tissue.

Answer:
