Class 7 Science — Nutrition in Plants Important Questions with Answers (Long answers)
Class 7 Science is the first full year photosynthesis, acids-bases and electric current share one textbook. The rationalized NCERT dropped a few older chapters; what remains is the set CBSE still samples in periodic tests. This hub writes one unique paragraph and a question cluster per surviving chapter so “nutrition in plants class 7 important questions” and “heat class 7 MCQ” resolve to real practice, not an empty subject shell. Answers stay behind a tap. Hindi and English stems sit together because most school papers are bilingual.
Autotrophs fix carbon with chlorophyll, sunlight, carbon dioxide and water; the word photosynthesis is not a decoration — it is the only food-making route for green plants. Stomata are the gates, not the kitchen. Heterotrophic modes — parasitic, insectivorous, saprotrophic — appear because a total autotroph story would hide Cuscuta and fungi. Nitrogen from soil is not “food”; it is a raw material after bacteria help. Questions here stay on NCERT diagrams of a leaf section and the starch test, not Class 10 life-process equations. You are on Nutrition in Plants (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
