Which group of plants lacks true roots, stems, and leaves?

Bryophytes (LIverworts, hornworts, and mosses) lack true roots, stems, and leaves.

Explanation:

The bryophyte is slightly differentiated, but they do not have true roots, stems, and leaves. The rhizoids are something similar to roots bryophytes have in their plant bodies.

The main plant body of the bryophytes is more like a thallus. Bryophytes are spore-producing plants that do not have vascular tissue.

Hence, bryophytes are the plants lack true roots, stem, and leaves.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
