10 Essential Plus One Botany Practical Viva Questions and Answers for Hsslive Students
Question 1: What is the difference between a compound and a simple microscope according to Hsslive practical guidelines?
Answer: According to Hsslive practical guidelines, a simple microscope uses a single lens for magnification, while a compound microscope uses multiple lenses (objective and eyepiece) to produce greater magnification. The Hsslive practical manual explains that compound microscopes provide much higher magnification (typically 40x to 1000x) compared to simple microscopes (usually up to 20x). Additionally, compound microscopes used in Hsslive laboratories feature adjustable objectives of different powers, allowing for various magnification levels suitable for detailed cellular observation.
Question 2: How would you prepare a temporary mount of an onion peel as per Hsslive Plus One Botany practical curriculum?
Answer: Following the Hsslive Plus One Botany practical curriculum, to prepare a temporary mount of an onion peel: First, break an onion into quarters and remove a small piece of the fleshy leaf. Using forceps, peel off the thin transparent epidermis from the concave surface. Place this peel in water in a watch glass. Transfer the peel to a clean slide using a brush. Add a drop of safranin stain for about 30 seconds. Remove excess stain with filter paper. Add a drop of glycerin and carefully place a coverslip using a needle to avoid air bubbles. The Hsslive practical manual emphasizes that the coverslip should be lowered at an angle to prevent air bubbles, which can interfere with observation.
Question 3: Explain the process of identifying stomata in a leaf peel according to Hsslive Plus One Botany practical procedures.
Answer: According to Hsslive Plus One Botany practical procedures, identifying stomata in a leaf peel involves carefully removing the epidermal layer from a leaf (commonly Rheo or Tradescantia as specified in the Hsslive manual). Under the microscope, stomata can be identified as specialized paired cells (guard cells) with a bean or kidney shape that contain chloroplasts. The Hsslive practical guide notes that these guard cells surround a pore called the stomatal aperture. The epidermis will also show regular epidermal cells that lack chloroplasts. As per Hsslive guidelines, students should be able to identify both the structure of stomata and explain their function in gaseous exchange and transpiration during the Plus One Botany Practical Viva Questions and Answers session.
Question 4: What are the key features you would use to identify a dicot stem slide during your Hsslive Plus One Botany Practical Viva?
Answer: During the Hsslive Plus One Botany Practical Viva, I would identify a dicot stem slide by observing these key features: vascular bundles arranged in a ring, presence of cambium between xylem and phloem (allowing for secondary growth), distinct regions of epidermis, cortex, and pith, endodermis may be less distinct, and presence of pericycle. The Hsslive practical manual also highlights that dicot stems typically show collenchyma beneath the epidermis for mechanical support and medullary rays extending from the pith through the vascular tissue. According to Hsslive guidelines, correctly identifying these structural elements demonstrates understanding of plant anatomy fundamentals.
Question 5: How do you differentiate between monocot and dicot roots as per the Hsslive Plus One Botany practical syllabus?
Answer: According to the Hsslive Plus One Botany practical syllabus, the key differences between monocot and dicot roots are: monocot roots have a polyarch stele (multiple xylem bundles) while dicot roots typically have 2-4 xylem bundles (diarch to tetrarch); monocot roots show alternating xylem and phloem in a ring around the central pith, whereas dicot roots usually have xylem in a star shape with phloem between the arms and no central pith; monocot roots typically have a distinct endodermis and pericycle, similar to dicot roots; and the cortex in monocot roots is usually extensive. The Hsslive practical guide emphasizes that identifying these differences is a common examination question that tests students’ observational skills.
Question 6: What is plasmolysis and how would you demonstrate it in a practical examination as per Hsslive guidelines?
Answer: According to Hsslive guidelines, plasmolysis is the shrinkage of the cell protoplast away from the cell wall due to osmotic loss of water in a hypertonic solution. To demonstrate plasmolysis in a practical examination, the Hsslive manual recommends: placing a fresh Rheo leaf peel on a slide with a drop of water, observing normal cells under the microscope, then adding a few drops of 10% sodium chloride solution from one side of the coverslip while drawing water from the opposite side using filter paper, and observing how the cell membrane shrinks away from the cell wall as water moves out of the cell by osmosis. The Hsslive practical curriculum emphasizes that this experiment demonstrates the concept of osmosis and the semi-permeable nature of cell membranes, which are fundamental concepts in plant physiology.
Question 7: How would you prepare and observe pollen germination as outlined in the Hsslive Plus One Botany Practical Viva Questions and Answers?
Answer: Following the Hsslive Plus One Botany Practical Viva Questions and Answers guidelines, to prepare and observe pollen germination: First, prepare a 10% sucrose solution with traces of boric acid and calcium nitrate. Place a drop on a clean slide. Collect fresh pollen grains (preferably from Hibiscus or lily flowers as recommended in the Hsslive manual) by gently tapping the anthers over the slide. Cover with a coverslip and incubate at room temperature for 30-60 minutes. Observe under the microscope to see pollen tubes emerging from the pollen grains. The Hsslive practical guide notes that successful pollen germination demonstrates how pollen tubes grow to deliver sperm cells to the ovule during fertilization, an essential concept in plant reproduction that students should understand thoroughly.
Question 8: What are the identifying features of different types of plant tissues as per Hsslive Plus One Botany practical curriculum?
Answer: According to the Hsslive Plus One Botany practical curriculum, the identifying features of different plant tissues are:
- Parenchyma: Thin-walled, living, isodiametric cells with intercellular spaces; the Hsslive manual describes these as the most common plant tissue type with functions in storage and photosynthesis.
- Collenchyma: Living cells with unevenly thickened primary walls, often located beneath the epidermis; Hsslive guidelines specify their role in providing mechanical support to growing plant parts.
- Sclerenchyma: Thick-walled, lignified, typically dead at maturity with supporting function; the Hsslive practical guide emphasizes their importance in plant structural integrity.
- Xylem: Complex tissue with vessels, tracheids, parenchyma, and fibers; as per Hsslive curriculum, functions in water and mineral transport.
- Phloem: Composed of sieve tubes, companion cells, parenchyma, and fibers; the Hsslive manual highlights its role in organic nutrient transport.
Question 9: How would you identify the stages of mitosis in an onion root tip slide during your Hsslive Plus One Botany Practical Viva?
Answer: During the Hsslive Plus One Botany Practical Viva, I would identify the stages of mitosis in an onion root tip slide by looking for these characteristics:
- Prophase: Chromosomes become visible as thin threads that gradually thicken and shorten; the Hsslive manual notes that the nuclear membrane and nucleolus begin to disappear.
- Metaphase: Chromosomes align at the equatorial plate; according to Hsslive guidelines, this is the best stage to count chromosomes.
- Anaphase: Sister chromatids separate and move toward opposite poles; the Hsslive practical curriculum emphasizes the V-shaped appearance of moving chromosomes.
- Telophase: Chromosomes reach the poles and begin to uncoil, nuclear membranes re-form, and cytokinesis begins; the Hsslive guide highlights the appearance of the cell plate in plant cells.
- Interphase: Distinct nucleus with nucleolus visible, chromosomes not distinguishable; Hsslive materials note this as the longest phase of the cell cycle.
Question 10: What are the steps to identify different types of inflorescence according to Hsslive Plus One Botany Practical Viva Questions and Answers?
Answer: According to Hsslive Plus One Botany Practical Viva Questions and Answers, to identify different types of inflorescence, follow these steps:
- Determine whether the inflorescence is racemose (indefinite) or cymose (definite); the Hsslive manual explains that in racemose types, the main axis continues to grow and flowers develop acropetally (from base to apex), while in cymose types, the main axis terminates in a flower and growth continues from lateral branches.
- For racemose inflorescences, identify specific types:
- Raceme: Flowers stalked along the main axis (e.g., Crotalaria); Hsslive examples include mustard and radish
- Spike: Sessile flowers on the main axis (e.g., Achyranthes); the Hsslive guide includes plantain as a common example
- Spadix: Sessile flowers on a fleshy axis with a spathe (e.g., Colocasia); Hsslive curriculum highlights aroids
- Catkin: Pendulous spike with unisexual flowers (e.g., Mulberry); Hsslive materials use mulberry as a typical example
- Umbel: Flower stalks arising from the same point (e.g., Coriander); the Hsslive manual includes onion as an example
- For cymose inflorescences, identify:
- Monochasial: One lateral branch develops at a time (e.g., Heliotropium); Hsslive guidelines specify scorpioid and helicoid cymes
- Dichasial: Two lateral branches develop (e.g., Jasmine); the Hsslive practical curriculum uses Dianthus as an example
- Polychasial: More than two branches develop (e.g., Calotropis); Hsslive materials note Euphorbia as a typical example
