Mosses and liverworts are called non-vascular plant because
A
they lack motile sperm
B
they lack seed
C
they lack vascular tissue
D
they lack true roots, stems and leaves
Explanation: 

Detailed explanation-1: -Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems and leaves. Xylem and phloem are absent. Bryophytes include liverworts, hornworts and mosses.

Detailed explanation-2: -Nonvascular plants are calle d bryophytes. Nonvascular plants include liverworts, hornworts, and mosses. They lack roots, stems, and leaves. Nonvascular plants are low-growing, reproduce with spores, and need a moist habitat.

Detailed explanation-3: -Liverworts grow flat along the substrate. These plants branch at the tip as they grow. Some liverworts have a broad, flat appearance while others are divided into tiny, leaflike segments. They do not have true roots, stems or leaves because they do not have vascular tissue (an internal transport system).

Detailed explanation-4: -Bryophytes. Bryophytes have no roots, leaves or stems. Moss and liverworts belong to this group. They are flowerless plants that grow in clumps.

Detailed explanation-5: -No, mosses do not have true roots, stems, or leaves. Mosses attach themselves to the surfaces on which they grow using small, clinging structures called rhizoids. While they help attach the plant to surfaces, they do not draw in or transfer moisture and nutrients to the plant the way true roots do.
