10 Essential Plus One Zoology Practical Viva Questions and Answers for Hsslive Students
Question 1: What is the difference between temporary and permanent slides in Hsslive practical examinations?
Answer: In Hsslive practical examinations, temporary slides are prepared for immediate observation and last for a short duration. They typically use water or glycerin as mounting media and do not undergo fixing or staining processes. Permanent slides, which are frequently used in Hsslive laboratories, undergo fixing, dehydration, clearing, infiltration, embedding, sectioning, staining, and mounting with permanent media like Canada balsam. According to Hsslive guidelines, permanent slides can be preserved for years and used repeatedly for observation, making them valuable teaching tools.
Question 2: Which chemicals are used for clearing during slide preparation according to Hsslive practical manual?
Answer: According to the Hsslive practical manual, xylene or clove oil is commonly used as a clearing agent during slide preparation. These chemicals, recommended in Hsslive practical procedures, make the tissue transparent by replacing alcohol in the specimen and are miscible with both alcohol and the mounting medium, ensuring high-quality microscopic preparations for observation.
Question 3: Explain the function of a compound microscope’s fine adjustment knob as specified in the Hsslive Plus One Zoology practical curriculum.
Answer: As specified in the Hsslive Plus One Zoology practical curriculum, the fine adjustment knob enables precise focusing by moving the stage or objective lens in very small increments. This allows for clear visualization of specimen details after the coarse adjustment knob has brought the specimen into approximate focus. Hsslive practical manuals emphasize that the fine adjustment is essential for observing cellular structures and other minute details clearly during laboratory examinations.
Question 4: What are the identifying features of Periplaneta americana (cockroach) that Hsslive students should know for the Plus One Zoology Practical Viva?
Answer: For Hsslive Plus One Zoology Practical Viva, students should identify Periplaneta americana by its reddish-brown color, flattened dorso-ventrally body, three pairs of jointed legs, two pairs of wings (forewings as tegmina and membranous hindwings), prominent antennae, compound eyes, and cerci at the posterior end. The Hsslive practical manual also notes that males have an additional pair of anal styles not present in females, which is an important distinguishing feature for specimen identification.
Question 5: List the components of a dissection set and their uses according to the Hsslive Plus One Zoology practical guidelines.
Answer: According to Hsslive Plus One Zoology practical guidelines, a standard dissection set includes:
- Scalpel: For making incisions and cuts in specimens
- Forceps: For holding and manipulating tissues without damage
- Scissors: For cutting tissues and materials during dissection
- Dissecting needles: For teasing apart delicate structures as emphasized in Hsslive manuals
- Dropper: For transferring liquids during specimen preparation
- Dissecting tray: To hold the specimen during dissection procedures
- Pins: To fix the specimen in place as per Hsslive practical methodology
Question 6: Explain the principle of sedimentation method used for collecting soil arthropods as per Hsslive practical syllabus.
Answer: According to the Hsslive practical syllabus, the sedimentation method relies on the difference in specific gravity between soil arthropods and water. When soil is mixed with water in a suitable container, the soil particles sink while arthropods float to the surface due to their hydrophobic exoskeleton and trapped air. The Hsslive practical manual instructs that floating arthropods can then be collected using a fine brush or pipette. This method, highlighted in Hsslive practical experiments, is particularly effective for extracting smaller soil arthropods for scientific study.
Question 7: How would you differentiate between monocot and dicot stems under a microscope during the Hsslive Plus One Zoology Practical Viva?
Answer: During the Hsslive Plus One Zoology Practical Viva, you should explain that monocot stems show scattered vascular bundles throughout the ground tissue, each bundle is surrounded by a bundle sheath, and they lack cambium (which means no secondary growth). Dicot stems have vascular bundles arranged in a ring, possess cambium for secondary growth, and typically show defined regions of cortex and pith. The Hsslive practical curriculum emphasizes that the presence of a distinct endodermis is also more common in monocots than dicots, which is an important distinguishing feature.
Question 8: What is the purpose of safranin stain in plant tissue observation according to Hsslive practical procedures?
Answer: According to Hsslive practical procedures, safranin is a basic dye that stains cell walls and nuclei red. The Hsslive manual explains that it has particular affinity for lignified, cutinized, or suberized cell walls, making it excellent for highlighting xylem elements and sclerenchyma tissue. In double staining procedures recommended by Hsslive, safranin is often paired with fast green to provide contrast between different plant tissues. This helps in clearly distinguishing various structural components during microscopic observation as required in Hsslive practical examinations.
Question 9: How would you identify Ascaris (roundworm) in a specimen collection during your Hsslive Plus One Zoology Practical Viva?
Answer: In your Hsslive Plus One Zoology Practical Viva, you should identify Ascaris by its cylindrical, non-segmented body with tapering ends, light brownish-yellow to pinkish color, and separate sexes with sexual dimorphism. The Hsslive practical guide notes that males are smaller (15-30 cm) with a curved posterior end and spicules, while females are larger (20-40 cm) with a straight posterior end. According to Hsslive standards, you should also mention that the body is covered with a tough cuticle and lacks appendages or suckers, and the mouth has three lips characteristic of the genus.
Question 10: What are the key differences between earthworm and leech specimens that Hsslive students should know for Plus One Zoology Practical Viva Questions and Answers?
Answer: For Hsslive Plus One Zoology Practical Viva Questions and Answers, students should note that earthworms (Pheretima) have cylindrical bodies with numerous segments, each bearing setae for locomotion, a less distinct anterior end, and no suckers. The Hsslive practical manual describes leeches (Hirudinaria) as having dorsoventrally flattened bodies, anterior and posterior suckers, no setae, distinct segmentation with external annuli, and a more pronounced anterior end. Hsslive practical curriculum emphasizes that earthworms are typically soil dwellers and detritivores, while leeches are often aquatic and many species are parasitic.
