Which of the following correctly compares two of the divisions of the plant kingdom?
A
Gymnosperms and angiosperms both reproduce sexually, but gymnosperms produce flowers or fruit, and angiosperms produce pollen cones and seed cones.
B
Nonvascular plants lack xylem and phloem and reproduce asexually, while angiosperms have xylem and phloem and reproduce sexually.
C
Seedless vascular plants and gymnosperms both reproduce asexually, but seedless vascular plants contain xylem, and gymnosperms contain xylem and phloem.
D
Seedless vascular plants and nonvascular plants both contain xylem and phloem, but seedless vascular plants reproduce asexually, and nonvascular plants reproduce sexually.
Explanation: 

Detailed explanation-1: -Which of the following correctly compares two of the divisions of the plant kingdom? Gymnosperms and angiosperms both reproduce sexually, but gymnosperms produce flowers or fruit, and angiosperms produce pollen cones and seed cones.

Detailed explanation-2: -Non-vascular plants, also known as bryophytes or lower plants, are plants mostly found in damp and moist areas and lack specialized vascular tissues. Both xylem and phloem are absent in these plants, and thus they are primitive plants with primitive parts.

Detailed explanation-3: -The main difference between vascular and non-vascular plants is that vascular plants contain a specialized xylem and phloem tissues for the transportation of water and foods, while non-vascular plants do not contain specialized vascular tissues for transport.

Detailed explanation-4: -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).
