Which structures allow lycophytes to grow bigger than mosses and liverworts? A. gametophytes and sporophytes
b. xylem and phloem
C. haploid and diploid
D. roots and stems

The structure that allows lycophytes to grow bigger than mosses and liverworts is xylem and phloem which is option B

Lycophytes are spore bearing vascular plants. Being a vascular plant, they possess vessels ( vascular tissues) which include:

The possession of the vessels makes the lycophytes appear bigger.

Mosses and liverworts belongs to the plant phylum Bryophyta. They do not have any vascular tissues that can be used to conduct water and food. This restricts their size.

Therefore, the structure that allows lycophytes to grow bigger than mosses and liverworts is xylem and phloem

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
