Detailed explanation-1: -Vascular plants evolved stems made of vascular tissues and lignin. Because of lignin, stems are stiff, so plants ca n grow high above the ground where they can get more light and air. Because of their vascular tissues, stems keep even tall plants supplied with water so they don’t dry out in the air.
Detailed explanation-2: -In all bryophytes, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. Because these plants lack lignified water-conducting tissues, they cannot become as tall as most vascular plants.
Detailed explanation-3: -Non-Vascular plants cannot grow very tall and because of their small sizes they can absorb enough water to carry materials throughout the plant.
