- A. Psilopsida
- B. Lycopsida
- C. Sphenopsida
- D. Prteropsida
Explanation: Equisetum belongs to Sphenopsida, also called the horsetail group, whose stems commonly have distinct nodes and internodes.
Correct answer: Sphenopsida- A. Psilopsids
- B. Lycopsids
- C. Sphenopsids
- D. Prteropsids
Explanation: Sphenopsids are called arthrophytes because their jointed, ribbed stems have conspicuous nodes and internodes, as seen in Equisetum.
Correct answer: Sphenopsids- A. Homosporous
- B. Hetrosporous
- C. Both depending upon the conditions
- D. None of these
Explanation: Selaginella is heterosporous, producing small microspores in microsporangia and larger megaspores in megasporangia.
Correct answer: Hetrosporous- A. Rhynia
- B. Psilophyton
- C. Psilotum
- D. Cooksonia
Explanation: Psilotum is a living representative of Psilopsida, the whisk-fern group.
Correct answer: Psilotum- A. Algae
- B. Bacteria
- C. Protozoa
- D. Fungus
Explanation: The underground gametophyte of Psilopsida lacks chlorophyll and obtains nourishment through a symbiotic association with fungi.
Correct answer: Fungus- A. Psilopsida
- B. Lycopsida
- C. Sphenopsida
- D. Pteropsida
Explanation: Ferns are classified under Pteropsida, the group of vascular plants with fronds and spore-producing structures.
Correct answer: Pteropsida- A. Sporophyte
- B. Gametophyte
- C. Both of these
- D. None of these
Explanation: Antheridia and archegonia are the male and female sex organs of bryophytes, and they develop on the haploid gametophyte generation.
Correct answer: Gametophyte- A. All are eukaryotes
- B. They are multicellular.
- C. Non-motile organisms
- D. They Are heterotrophes
Explanation: Plants are eukaryotic, multicellular and generally non-motile organisms, and most make organic food by photosynthesis, so they are…
Correct answer: They Are heterotrophes- A. Coelenterates
- B. Platyhelminthes
- C. Aschelminthes
- D. Annelids
Explanation: Aschelminthes, including nematodes, are pseudocoelomates because their body cavity is derived from the persistent blastocoel and is not…
Correct answer: Aschelminthes- A. Dugesia
- B. Fasciola
- C. Taenia
- D. None of these
Explanation: Dugesia is a free-living planarian that belongs to Platyhelminthes, whereas Fasciola and Taenia are parasitic flatworms.
Correct answer: Dugesia- A. 0.2 mm
- B. 0.2 nm
- C. 0.2 m
- D. none of these
Explanation: An electron microscope uses electrons with much shorter wavelengths than visible light, giving a resolving power of about 0.2 nm.
Correct answer: 0.2 nm- A. Excretory system
- B. Digestive system
- C. Criculatory system
- D. Nervous system
Explanation: Annelid segmentation is reflected in the arrangement of their circulatory vessels and repeated connecting vessels across body segments.
Correct answer: Criculatory system- A. Sac - like digestive system
- B. Tube - like digestive system
- C. Circulatory system
- D. Respiratory system
Explanation: Nematodes possess a complete, tube-like digestive system with a mouth, intestine and anus, allowing food to move in one direction.
Correct answer: Tube - like digestive system- A. Rhabditis
- B. Enterobius vermicularis
- C. Ancylostoma duodenale
- D. Taenia solium
Explanation: Enterobius vermicularis is the pinworm, also called the threadworm, and commonly infects the human intestine.
Correct answer: Enterobius vermicularis- A. Crustacea
- B. Insecta
- C. Arachnida
- D. Myriapoda
Explanation: Arachnids generally develop directly, so the young resemble small adults and there is no true larval-to-adult metamorphosis.
Correct answer: Arachnida- A. Echinoderms
- B. Hemichordates
- C. Vertebrates
- D. Chordates
Explanation: Hemichordates are called prechordates because they show some chordate-like features but are considered an evolutionary group preceding…
Correct answer: Hemichordates- A. Head
- B. Ventral muscular foot
- C. Dorsal visceral region
- D. All of these
Explanation: The molluscan mantle is a dorsal fold of the body wall that covers the visceral mass and usually forms the mantle cavity.
Correct answer: Dorsal visceral region- A. Nematods
- B. Arthropods
- C. Molluscs
- D. None of these
Explanation: Arthropods and annelids are traditionally considered to share a common segmented ancestor, since both show metamerism and similar…
Correct answer: Arthropods- A. Tentacles
- B. Palps
- C. Eyes
- D. All of these
Explanation: Polychaetes possess sensory and feeding structures such as tentacles and palps, and many species also have eyes.
Correct answer: All of these- A. Ventral nerve cord
- B. Dorsal nerve cord
- C. Lateral nerve cord
- D. All of these
Explanation: The nematode nervous system includes a nerve ring and longitudinal dorsal, ventral and lateral nerve cords, so all three listed cords are…
