FAQs on PPT: Food from Plants - Science for Class 1

1. What are some examples of food that come from plants?
Ans. Food from plants includes a wide variety of items such as fruits (like apples and bananas), vegetables (like carrots and spinach), grains (like rice and wheat), nuts (like almonds and walnuts), and legumes (like beans and lentils). These foods provide essential nutrients and are important for a balanced diet.
2. Why are plants important for our food?
Ans. Plants are crucial for our food because they produce the fruits, vegetables, grains, and other food items that make up our diet. They are primary producers in the food chain, converting sunlight into energy through photosynthesis, and provide essential vitamins, minerals, and fiber that are vital for our health.
3. How do plants grow to produce food?
Ans. Plants grow through a process called photosynthesis, where they use sunlight, carbon dioxide from the air, and water from the soil to create energy and produce food. This process takes place in the leaves, where chlorophyll captures sunlight. As plants grow, they develop roots, stems, and leaves, which help them absorb nutrients and water.
4. Can all parts of a plant be eaten?
Ans. Not all parts of a plant are edible, but many can be. Common edible parts include the roots (like carrots and beets), stems (like asparagus), leaves (like lettuce), flowers (like broccoli), and fruits (like tomatoes). However, some parts, such as certain seeds, leaves, or flowers, may be toxic or not suitable for consumption, so it's important to know which parts are safe to eat.
5. How do we know which plants are safe to eat?
Ans. We can determine which plants are safe to eat through research, traditional knowledge, and guidance from experts. Many edible plants are well-documented in cookbooks and agricultural resources. Additionally, some plants are cultivated for food and regulated for safety in markets. Always ensure that you have accurate information and consult reliable sources before consuming wild plants.
