Sample Viva Questions and Model Answers

Here are some sample questions with suggested answers to help you prepare:

Q1: Identify the specimen shown and mention its distinctive features.

Answer: The specimen is a Hydra. It is a freshwater cnidarian characterized by a tubular body with tentacles surrounding the mouth. Its body is divided into a basal disc and a cylindrical column. The presence of cnidocytes on tentacles is a distinctive feature.

Q2: How do you prepare a permanent slide of a transverse section of a plant stem?

Answer: The process involves fixing the specimen in formalin, dehydrating it through alcohol series, clearing with xylene, embedding in paraffin wax, sectioning with a microtome, mounting on a slide, and staining with dyes like safranin or iodine. Finally, the slide is covered with a cover slip for observation.

Q3: What is the significance of observing the cross-section of a dicot stem?

Answer: Observing a dicot stem's cross-section helps understand the arrangement of tissues such as epidermis, cortex, vascular bundles (xylem and phloem), and pith. It aids in understanding plant structure, transport mechanisms, and adaptations for support and conduction.
