Life Processes in Plants

Start here

Nobody feeds the money plant on the terrace. What does it live on?

A leaf makes glucose. Light, air and water go in.

This is Chapter 10, Life Processes in Plants, in your NCERT book.

What you will do

  • See what a leaf needs to make food.
  • Find the parts of a leaf that do the work.
  • Test a leaf for starch, its stored food.
  • Follow water up and food around.
  • Tell photosynthesis, making food, from respiration, getting energy from food.
  • Test growth in sun, water and the dark.
  • Show a leaf needs carbon dioxide.
  • Find what a leaf gives out.
  • Learn why some red leaves can still make food.

Try the small lab first in each lesson. The words come after.

Need a quick recap?

  • Food and air (Class 6) — animals take in food. Plants make their own.
  • Respiration (Chapter 9) — every living thing respires.

Stay safe

Some tests use alcohol, fire or strong chemicals. Only a teacher does them. Never try them alone.
