One-Word Answer Type Questions
Topic: Synthesis of Plant Food Other Than Carbohydrates
1. Question: Which nutrient present in proteins is not found in carbohydrates?
• Answer: Nitrogen
• Explanation: Proteins are nitrogenous substances, whereas carbohydrates contain only carbon, hydrogen, and oxygen.
2. Question: In which form do plants absorb nitrogen from the soil?
• Answer: Soluble
• Explanation: Plants absorb nitrogen in a soluble form from the soil, as they cannot use nitrogen gas directly from the air.
3. Question: Name the bacteria that converts atmospheric nitrogen into a usable form.
• Answer: Rhizobium
• Explanation: Rhizobium bacteria live in the root nodules of leguminous plants and convert atmospheric nitrogen into soluble nitrogen compounds.
4. Question: What type of plants have root nodules that contain nitrogen-fixing bacteria?
• Answer: Leguminous
• Explanation: Leguminous plants like gram, peas, moong, and beans have root nodules containing Rhizobium bacteria for nitrogen fixation.
5. Question: What is the process of using atmospheric nitrogen by plants called?
• Answer: Nitrogen fixation
• Explanation: Nitrogen fixation is the process of converting atmospheric nitrogen into a form that plants can absorb and use.
6. Question: Which mineral nutrient is essential for the synthesis of proteins in plants?
• Answer: Nitrogen
• Explanation: Nitrogen is an essential mineral for protein synthesis in plants.
7. Question: Name the component of food synthesized by plants using nitrogen.
• Answer: Proteins
• Explanation: Plants use nitrogen, along with carbohydrates, to synthesize proteins.
8. Question: What type of relationship exists between Rhizobium bacteria and leguminous plants?
• Answer: Symbiotic
• Explanation: Rhizobium bacteria and leguminous plants have a symbiotic relationship, where both benefit from each other.
9. Question: Apart from proteins, what other nutrient is synthesized in plants using minerals?
• Answer: Vitamins
• Explanation: Along with carbohydrates and proteins, plants also synthesize vitamins using minerals from the soil.
10. Question: What is added to the soil by farmers to fulfill the nitrogen requirement of plants?
• Answer: Fertiliser
• Explanation: Farmers add nitrogen-rich fertilisers to the soil to help plants in synthesizing proteins and other nutrients.
