Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
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: -Nonvascular plants are called 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-2: -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.

Detailed explanation-3: -Mosses, liverworts and hornworts are collectively called “bryophytes.” Bryophytes are nonvascular plants: They do not have special tissues-tissues that botanists call “xylem” and “phloem”-to transport fluids and nutrients internally. Additionally, bryophytes do not produce flowers and seeds.
