Introduction
Nutrition in plants is one of the most important chapters in Class 7 Science because it explains how plants prepare food and survive in different environments. Besides photosynthesis, students should also understand symbiotic relationships, nutrient requirements, and special adaptations in plants. This practice set contains fresh NCERT-based questions without repeating previous concepts.
What You Will Learn
✔ Importance of glucose in plants
✔ Role of roots and leaves
✔ Symbiotic nutrition
✔ Mineral nutrients
✔ Insectivorous plants
✔ Concept-based NCERT questions
✔ Exam-oriented reasoning
Why This Topic Is Important
The concepts in this chapter help students understand ecosystems, food chains, and plant life. These topics are frequently tested in school examinations, Olympiads, and scholarship exams through application-based and reasoning questions.
1. MCQ Questions with Detailed Solutions
Q1. What is the immediate food prepared by plants during photosynthesis?
A) Protein
B) Glucose
C) Starch
D) Cellulose
Answer
B) Glucose
Concept Behind This Question
Plants first prepare glucose, which may later be converted into starch for storage.
Step-by-Step Solution
During photosynthesis, plants produce glucose.
Excess glucose is converted into starch and stored in different plant parts.
Therefore, the correct answer is B.
Exam Tip
Glucose = First Food Produced
Q2. Which plant part mainly absorbs water and minerals from the soil?
A) Stem
B) Flower
C) Roots
D) Fruit
Answer
C) Roots
Concept Behind This Question
Roots absorb water and minerals required for plant growth and photosynthesis.
Step-by-Step Solution
Roots spread through the soil.
They absorb water and mineral nutrients and send them to the stem.
Therefore, the correct answer is C.
Exam Tip
Roots = Absorption of Water & Minerals
Q3. Which pair correctly represents a symbiotic relationship?
A) Cuscuta – Mango Tree
B) Pitcher Plant – Insect
C) Alga – Fungus
D) Mushroom – Dead Leaves
Answer
C) Alga – Fungus
Concept Behind This Question
Lichens are formed by algae and fungi living together for mutual benefit.
Step-by-Step Solution
The alga prepares food through photosynthesis.
The fungus provides water, minerals, and shelter.
Both benefit from the relationship.
Therefore, the correct answer is C.
Exam Tip
Lichen = Alga + Fungus = Symbiosis
Q4. Which nutrient is mainly responsible for healthy plant growth and protein formation?
A) Nitrogen
B) Oxygen
C) Carbon Dioxide
D) Hydrogen
Answer
A) Nitrogen
Concept Behind This Question
Nitrogen is essential for protein synthesis and plant development.
Step-by-Step Solution
Plants require nitrogen to make proteins.
A lack of nitrogen causes poor growth and yellow leaves.
Therefore, the correct answer is A.
Exam Tip
Nitrogen = Protein + Growth
Q5. Why do insectivorous plants digest insects?
A) To obtain water
B) To obtain nitrogen
C) To obtain sunlight
D) To obtain oxygen
Answer
B) To obtain nitrogen
Concept Behind This Question
Insectivorous plants grow in nitrogen-deficient soil.
Step-by-Step Solution
Although insectivorous plants prepare food through photosynthesis, they trap insects because the soil lacks nitrogen.
Digesting insects supplies this important nutrient.
Therefore, the correct answer is B.
Exam Tip
Trap Insects → Get Nitrogen
Important Formulas & Concepts
1. First Product of Photosynthesis
Glucose is the first food prepared by plants.
2. Food Storage
Extra glucose is converted into starch for storage.
3. Roots
Absorb water and minerals from the soil.
4. Symbiosis
Both organisms benefit from living together.
Example: Alga + Fungus (Lichen)
5. Nitrogen
Required for protein synthesis and healthy plant growth.
