1. Which of the plant groups needs both land and water to complete their life cycle?
A. Tracheophyta
B. Pteridophyta
C. Thallophyta
D. Bryophyta
ANSWER: D.Bryophyta
SOLUTION :”Bryophyta” is the plant group which requires both land and water to complete its life cycle.
2. A plant that has seeds but no flowers and fruits?
A. Bryophytes
B. Gymnosperms
C. Mosses
D. Pteridophytes
ANSWER:B.Gymnosperms
SOLUTION:Gymnosperms are seed-producing plants but they do not bear flowers. Phanerogams consist of both angiosperms and gymnosperms.
3. Most primitive vascular plants?
A. Mosses
B. Cycads
C. Kelps
D. Ferns
ANSWER :D.Ferns
SOLUTION:Ferns, also known as pteridophytes, are considered the most primitive vascular plants.
4. Plants that possess spores and embryo but lack vascular tissues and seeds?
A. Rhodophyta
B. Bryophyta
C. Pteridophyta
D. Phaeophyta
ANSWER: B.Bryophyta
SOLUTION: Bryophytes produce spores and embryos but lack seeds and vascular tissues.
5. Which one is not an exception in angiosperms?
A. Double fertilization
B. Secondary growth
C. Presence of vessels
D. Autotrophic nutrition
ANSWER:A.Double fertilization
SOLUTION:So, the correct answer is ‘Double fertilisation’.
6. Pteridophytes differ from mosses in___________.
A. Independent gametophyte
B. Dependent gametophyte
C. Flagellate antherozoids
D. Independent and dominant sporophyte
ANSWER: D.Independent and dominant sporophyte
SOLUTION:Pteridophytes differ from mosses/bryophytes in possessing well developed vascular system.
7. Plants reproducing by spores are grouped under_________.
A. Bryophytes
B. Sporophytes
C. Cryptogams
D. Thallophytes
ANSWER:C.Cryptogams
SOLUTION :Cryptogams refer to the plants and fungi that do not reproduce by seeds. Besides these, the cryptogams are also known to reproduce by means of spores. All spore producing plants including mosses and ferns do not reproduce by seeds are hence, known as cryptogams.
8. First plants to inhabit the land _______.
A. Angiosperms
B. Bryophytes
C. Gymnosperms
D. Pteridophytes
ANSWER: B.Bryophytes
SOLUTION:Bryophytes, which include liverworts, hornworts, and mosses, are considered the first plants to inhabit land. They are also known as the “amphibians of the plant kingdom”
9. Double fertilization is the characteristic of_______.
A. Algae
B. Gymnosperms
C. Fungi
D. Angiosperms
ANSWER:D.Angiosperms
SOLUTION: Double fertilization is a characteristic of flowering plants, also known as angiosperms.
10. Plants having vascular tissue without seeds________.
A. Angiosperm
B. Pteridophytes
C. Bryophytes
D. Gymnosperms
ANSWER: B.Pteridophytes
SOLUTION:
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.
