Question

Seed-producing plants are called:

• A. spermatophytes
• B. pteridophytes
• C. bryophytes
• D. embryophytes

Answer 1

The correct option is A

spermatophytes

The correct option is A.

Explanation of the correct option:

1. The spermatophytes, also known as seed plants, produce seeds for their reproduction.
2. The plant has roots, stems, leaves, and seed-bearing structures.
3. They have vascular tissue that is highly developed with xylem tissue consisting of both xylem tissue and tracheids.

Explanation of the incorrect option:

Option B:

1. Pteridophytes are free-spore vascular plants that have a life cycle with alternating gametophyte and sporophyte phases that are independent at maturity.
2. The body of the sporophyte is well-differentiated into roots, stem, and leaves and the root system is always adventitious.
3. Psilopsida, Lycopsida, Sphenopsida, and Pteropsida are the four groups of pteridophytes.

Option C:

1. Bryophytes are the small flowerless green plants of the division Bryophyta, which comprises the mosses and liverworts.
2. Hornworts, liverworts, and mosses are three main groups of bryophytes.
3. Prominent bryophytes characteristics are the absence of true roots, stems, and leaves, but rhizoids perform the function of roots, especially anchoring the plants to the surface.

Option D:

1. Embryophytes are complex multicellular eukaryotes with specialized reproductive organs.
2. They use the energy of sunlight to synthesize their food from carbon dioxide and water.

Final answer: Spermatophytes are seed-producing plants and are called seed plants.
