Class 11 Biology
Mannitol is the stored food in which group of algae?
A Chlorophyceae (green algae)
B Phaeophyceae (brown algae)
C Rhodophyceae (red algae)
D Cyanophyceae (blue-green algae)
Class 11 Biology
Gymnosperms are characterized by naked seeds that are not enclosed within a fruit. Which of the following statements about gymnosperms is correct?
A All gymnosperms are flowering plants
B Gymnosperms produce double fertilization
C Oryzophagus is an example of an insect pollinator in gymnosperms
D Gymnosperms have a dominant gametophyte phase
Class 11 Biology
In pteridophytes, the dominant phase of the life cycle is the sporophyte, which is differentiated into true roots, stems, and leaves. What structure do pteridophytes typically possess for water conduction that distinguishes them from bryophytes?
A Phloem
B Xylem with vessels
C Xylem with tracheids only
D Conducting parenchyma only
Class 11 Biology
Selaginella is classified as a pteridophyte because it:
A Has true roots, stems, leaves (fronds) and vascular tissue, reproduces via spores
B Produces flowers and fruits
C Lacks vascular tissue and reproduces by spores
D Has seeds enclosed in fruits
Class 11 Biology
Which of the following is a characteristic feature of bryophytes, earning them the nickname "amphibians of the plant kingdom"?
A They require water for fertilisation as motile sperm swim to the egg
B They produce seeds but not flowers
C They have well-developed vascular tissue (xylem and phloem)
D They grow only in aquatic environments
Class 11 Biology
Which of the following is the correct characteristic of gymnosperms?
A They produce naked seeds (not enclosed in fruits) and are mostly woody trees/shrubs
B They produce seeds enclosed in fruits (angiosperms)
C They reproduce by spores like pteridophytes
D They are non-vascular plants like bryophytes
Class 11 Biology
Bryophytes are often called "amphibians of the plant kingdom." This analogy is because:
A They can live in water but cannot reproduce in water
B They require water for fertilization as the male gametes (antherozoids) must swim to the egg
C They have both aquatic and terrestrial forms that can switch depending on the season
D They possess adaptations for water conservation like cuticle and stomata
Class 11 Biology
Which of the following best describes the alternation of generations in plants?
A The life cycle alternates between a multicellular haploid gametophyte and a multicellular diploid sporophyte
B The plant alternates between summer and winter forms
C The plant alternates between vegetative and reproductive phases only
D There is no alternation; plants are always diploid
