plants that lack tissues to move water and food
A
nonvascular plant
B
gravitropism
C
carpel
D
None of the above
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 lack differentiated tissues like vascular tissues, which separate them from vascular plants that have vascular tissues to transport nutrients and water. They also lack stems, roots, and leaves. But they have stem-like, root-like, and leaf-like structures that work just like stem, roots, and leaves.

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.

Detailed explanation-4: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.

Detailed explanation-5: -Characteristics of Nonvascular Plants They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).
