Which of the following statements accurately differentiates Archaebacteria from Eubacteria?
Archaebacteria have peptidoglycan in their cell walls, while Eubacteria do not.
Archaebacteria lack introns in their genes, while Eubacteria have introns.
Archaebacteria have branched chain lipids in their cell membranes, while Eubacteria have straight chain lipids.
Archaebacteria are sensitive to antibiotics, while Eubacteria are resistant.
The heterosporous nature of Selaginella is considered an evolutionary advancement because it:
Leads to the development of seeds
Increases the number of spores produced
Allows for asexual reproduction
Simplifies the gametophyte generation
Members of the fungal class Phycomycetes are unique among fungi in several ways. Which of the following features is NOT characteristic of Phycomycetes?
Presence of coenocytic hyphae
Production of zoospores with flagella
Formation of asci containing ascospores
A tendency to thrive in aquatic or moist environments
If Mendel had chosen a plant with a very long generation time, which aspect of his experiments would have been MOST negatively affected?
The ease of cross-pollination.
The observability of contrasting traits.
The speed of obtaining results and observing inheritance patterns.
The control over self-pollination.
Which of the following is NOT a characteristic of the prokaryotes involved in biogas production from ruminant dung?
Are prokaryotic
Belong to Archaebacteria
Essential for methane production
Require oxygen for survival
Which of these is NOT a characteristic of organisms that commonly reproduce asexually?
Rapid population growth.
Ability to thrive in stable environments.
Complex multicellular structure.
Production of genetically identical offspring.
Assertion: Halophiles are found in environments with high salt concentrations.
Reason: They possess specialized adaptations to regulate osmotic pressure.
Choose the correct option:
Both assertion and reason are true, and reason is the correct explanation for assertion
Both assertion and reason are true, but reason is not the correct explanation for assertion
Assertion is true, but reason is false
Assertion is false, but reason is true
Which of the following is NOT a characteristic of Deuteromycetes, the imperfect fungi involved in decomposition?
Lack of a known sexual stage
Saprophytic nature
Formation of a dikaryon stage
Contribution to mineral cycling
Which feature is less emphasized in the modern classification of fungi compared to the others?
Molecular data (e.g., rRNA sequences)
Reproductive structures
Biochemical characteristics
Fossil record
Consider the following statements
I. Mycelium is branched and septate
II. The asexual spores are generally not formed
III. Vegetative reproduction takes place by framentation
IV. Sex organs are absent but sexual reproduction takes place by somatogamy
V. Karyogamy and meiosis takes place in basidium to form haploid four basidiospores
Vi. Basidia are arranged in fruiting bodies called basidiocarp
The above statements are assigned to
Sac fungi
Bracket fungi
Imperfecti fungi
Club fungi
