NCERT Class 7 Science Curiosity: Chapter 10 — Life Processes in Plants
This chapter, "Life Processes in Plants," from NCERT's Class 7 Science Curiosity book, explores how plants grow and obtain nutrients. It begins by recalling that all living beings grow and need food, contrasting animal nutrition with plant nutrition. The chapter introduces the concept of plant growth, noting changes like new leaves, branches, increased height, and stem thickening. It prompts students to consider factors influencing growth, such as water and sunlight, and proposes an experiment (Activity 10.1) to test these hypotheses. The experiment involves three pots with saplings, varying conditions of sunlight and water to observe their effects on plant growth, laying the groundwork for understanding photosynthesis and nutrient uptake.
