Question

Which group of plants bear flowers?
A. Pteridophytes
B. Angiosperms
C. Gymnosperms
D. Bryophytes

Answer 1

Hint: In following plants, pollen grains and ovule are developed in specialized structures called flowers. Angiosperms are flowering plants. In angiosperms, the seeds are enclosed by fruits.

Complete Answer:
A. Pteridophytes: They are also called vascular cryptogams as they possess xylem and phloem. Pteridophytes include horsetails and ferns. They have compact structures called strabili or cones for example – Selaginella and equisetum. Seed habit is considered an important step in evolution.
B. Angiosperms: Angiosperm means enclosed seed as the ovules are enclosed in ovary. Angiosperms, or flowering plants, constitute most dominant vascular plants of present day flora. They are known as flowering plants because they produce their reproductive structure in the flower.
C. Gymnosperms: the meaning of Gymnosperms, Gymnos – naked, sperms – seeds i.e. plants with naked seeds. Gymnosperms are also known as seed bearing plants. These plants were evolved with fully developed vascular systems. These were tall seed bearing plants.
D. Bryophytes: They are known as “Amphibians of the plant kingdom”. Bryophytes grow in marshy land which lack oxygen. Common examples of Bryophytes are Liverworts, Moss grass etc.

The correct answer is “B”, Angiosperms.

Note: In pteridophytes reproduction occurs by spores. Bryophytes also germinate to produce gametophyte. Gymnosperms have naked seeds. Seeds ripe and become dry are shed, seeds contain sporophyte in the form of dormant embryos. Seeds are protected by a seed coat. Angiosperms are further categories into monocots and dicots.
