Class 7 Science Chapter 10, Life Processes in Plants, investigates how plants make their own food, exchange gases, transport water, minerals and food through vascular tissues, and respire day and night to release energy for growth.
What Class 7 Science Chapter 10 Covers
10.1–10.2 How Plants Grow & Get Food (Photosynthesis) tests the conditions essential for photosynthesis—sunlight, chlorophyll in leaves (‘food factories’, 10.2.1), carbon dioxide from air (10.2.2) and water—using the iodine starch test, and examines gas exchange through stomata (guard cells, 10.2.3–10.2.4).
10.3 Transport in Plants demonstrates upward transport of water and dissolved minerals from roots through xylem (10.3.1) and translocation of food prepared in leaves to all parts of the plant through phloem (10.3.2).
10.4 Do Plants Respire? proves with germinating seeds and lime water that plants respire continuously, taking in oxygen and releasing carbon dioxide to break down glucose for energy.

FAQ
What is the word equation for photosynthesis?
Carbon dioxide + Water —(in the presence of Sunlight and Chlorophyll)→ Glucose (Carbohydrate) + Oxygen.
What is the difference between xylem and phloem in plants?
Xylem vessels transport water and dissolved minerals upward from the roots to the stems and leaves, whereas phloem transports food (sugars) made in the leaves to all other parts of the plant.
