AP BIOLOGY

Detailed explanation-1: -Pteridophytes are members of cryptogams, which means they have inconspicuous reproductive organs. Hence, Pteridophytes neither have flowers nor they produce seeds. They have naked embryos that are called spores.

Detailed explanation-2: -These are vascular plants that reproduce through spores. Such plants possess a system of vascular tissues and they also have a well-differentiated body with roots, stems, and leaves. They have well-developed xylem and phloem tissues for the transportation of food and water.

Detailed explanation-3: -Pteridophytes are vascular plants. The plant body is leafy or thalloid. The plant body is differentiated into roots, stem and leaves. No vascular tissues.

Detailed explanation-4: -Pteridophyta is a group of non-seed forming, vascular cryptogams, i.e., these contain vascular tissues for the conduction of minerals and water but do not produce seeds.

Detailed explanation-5: -A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as “cryptogams", meaning that their means of reproduction is hidden.
