SAQ-1 : Why is it necessary to de-starch a plant before performing any experiment on photosynthesis? (OR) Give importance of destarch plant in photosynthesis experiments.

Before conducting experiments on photosynthesis, the process of how plants make food, scientists often ‘de-starch’ the plants. This step is crucial for several reasons:

1. Start with a Clean Slate: Plants naturally store food as starch. By de-starching, scientists ensure that any starch found later in the experiment is newly synthesized during the experiment, not pre-existing.
2. Focus on New Food Making: De-starching allows scientists to observe how plants produce starch from scratch during their experiments, eliminating the interference of any old starch.
3. Get Accurate Results: Using a de-starched plant ensures that the experimental results reflect only the activities occurring during the test, providing clear and accurate data.

In essence, de-starching plants is a critical step that helps scientists accurately study the processes of how and when plants synthesize their food, without the confusion of pre-existing reserves influencing the results.

SAQ-2 : Why is not possible to demonstrate respiration in green plant kept in sunlight? (OR) The rate of respiration during day time is less compared during night time. Explain.

1. Photosynthesis and Respiration in Green Plants: In green plants, photosynthesis and respiration are ongoing processes, but demonstrating respiration in sunlight is challenging because photosynthesis becomes the dominant activity.
2. Photosynthesis During Daytime: During the day, plants use sunlight to power photosynthesis, converting carbon dioxide into glucose and releasing oxygen. This process rapidly consumes the carbon dioxide produced by respiration, making it difficult to observe respiration as an individual process.
3. Respiration Visibility at Night: At night, when photosynthesis ceases due to the absence of sunlight, respiration, which releases carbon dioxide, becomes more evident.
4. Study and Demonstration Distinction: This distinction between day and night activities facilitates the study and demonstration of respiration in plants during the nighttime, in contrast to daytime when photosynthesis is more prominent.

SAQ-3 : Prepare four questions for the Gastro-enterologist to know the problems that occur in the digestive system.

Introduction

Gastroenterologists are medical experts specializing in diagnosing and treating disorders of the digestive system. For patients with digestive issues, asking precise questions is crucial to identify the root causes and determine the most effective treatment. Here are four key questions that a gastroenterologist might ask:

1. What specific symptoms are you experiencing related to your digestive tract? This question helps identify the type and cause of digestive disturbances, such as indigestion, bloating, or irregular bowel movements.
2. What factors might contribute to the formation of ulcers in the intestines? Understanding the causes behind intestinal ulcers, such as infections, medication use, or lifestyle factors, is vital for effective treatment.
3. How do the liver and pancreas contribute to digestion, and what are the signs of their malfunction? This question assesses the patient’s understanding of these organs’ roles and helps evaluate symptoms indicating their dysfunction.
4. Can you describe the range of symptoms commonly associated with gastrointestinal disorders? Gathering information on symptoms like abdominal pain, diarrhea, constipation, and unexplained weight loss can guide further diagnosis and treatment.

Summary

These questions are essential for gastroenterologists to gain insights into a patient’s digestive issues, uncover possible causes, and plan appropriate treatments.

SAQ-4 : Write down four steps to be followed in your daily life to prevent malnutrition.

Introduction

Malnutrition, resulting from inadequate nutrient intake or an imbalance in nutrients, can cause various health issues. Preventing malnutrition is key to maintaining good health. Here are four practical steps for daily life to help prevent malnutrition:

1. Having a Well-Balanced Diet: Ensure your diet includes a variety of foods from all food groups. Incorporate different fruits, vegetables, whole grains, lean proteins, and dairy products (or alternatives). A varied diet ensures a comprehensive nutrient intake.
2. Consume Food with Low Fats and Rich in Carbohydrates and Proteins: Choose foods low in saturated and trans fats, and high in monounsaturated and polyunsaturated fats. Include complex carbohydrates, like whole grains and legumes, and adequate proteins from lean meat, poultry, fish, beans, nuts, and dairy.
3. Drinking Plenty of Water: Proper hydration is vital for digestion and nutrient absorption. Drink sufficient water daily to help transport nutrients and eliminate waste, while avoiding sugary drinks.
4. Engage in Moderate Physical Activity: Regular exercise, such as walking, cycling, or swimming, improves appetite and digestion, contributing to the prevention of malnutrition. Ensure your physical activity is consistent and appropriate for your health and fitness level.

Summary

Preventing malnutrition involves a well-balanced diet, rich in essential nutrients, staying hydrated, and engaging in regular physical activity. These steps, along with regular medical check-ups, can help ensure good health and prevent malnutrition-related issues.
