- Question 6 In the evolution of vascular plants, there is a trend toward the: A above-ground parts becoming structurally similar to the below-ground parts. B progressive reduction of the sporophyte. sporophyte becoming nutritionally dependent on the gametophyte. Dincreased protection of the gametophyte by the sporophyte. production of seeds in all lineagesT/F question The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules. Plant tissues grow from meristem cells that continually divide during the growing season. Primary plant growth involves thickening of the stems and roots.
