Class 6 Science Chapter 10 Living Creatures – Revision Notes

Living Creatures looks at the traits that mark something as alive, movement, growth, nutrition, respiration, and more, and this summary breaks each characteristic down with everyday examples.

Characteristics of Living Things

• Movement — not always locomotion; includes plant movements like leaf-folding, climbing, trapping.
• Growth — increase in size, linked to nutrition.
• Nutrition — food needed for growth and energy.
• Respiration — breathing is part of this larger process; plants respire via stomata.
• Excretion — removal of waste (sweat/urine in animals; leaf-edge droplets in some plants).
• Response to stimuli — reacting to a stimulus (any prompting event or thing).
• Reproduction — producing new individuals of one’s own kind.

A being is considered dead when it can no longer show these characteristics, even with resources available.

Seed Germination

• Needs: water, air, and appropriate light/darkness (varies by seed type).
• Waterlogged soil can prevent germination by excluding air.
• Dry, cool, airtight storage of grains prevents unwanted germination/spoilage.

Plant Growth Direction

• Shoots grow toward light; roots grow downward — regardless of the seed/pot’s orientation.

Life Cycles

• Plant (bean): seed → germination → leaves → flowers → fruit/pod with seeds → death.
• Mosquito: egg → larva → pupa → adult (all in/near stagnant water until the adult stage).
• Frog: spawn (egg cluster) → embryo → tadpole with tail → tadpole with legs → froglet → adult.

Common Mistakes to Avoid

• Don’t judge “living” by movement alone — cars move but aren’t alive; many plants barely move but are alive.
• An object originating from something living (like a fallen log) isn’t automatically living itself.
• Growth alone (like a crystal “growing”) doesn’t make something alive — all characteristics must be present together.

One-Line Summary

Living things share seven characteristics together — movement, growth, nutrition, respiration, excretion, response to stimuli, and reproduction — and this chapter traces those characteristics through seed germination and the life cycles of a plant, a mosquito, and a frog.

Frequently Asked Questions

What are some basic characteristics that distinguish living creatures from non-living things?
Living creatures typically show characteristics such as growth, movement, reproduction, response to stimuli, and the need for nutrition, while non-living things do not display these on their own.

Why is response to stimuli considered an important sign of life?
Response to stimuli shows that an organism can sense changes in its environment, such as light, touch, or temperature, and react accordingly, reflecting internal biological processes unique to living things.
