CBSE Notes – Key Points
These notes are useful for quick revision before examinations. Read the important definitions, tables, scientific terms, and key facts carefully to strengthen your conceptual understanding.
Important Keywords
The following keywords are frequently used in this chapter and should be remembered carefully.
| Keyword | Meaning |
|---|---|
| Living Organism | An organism that performs all life processes. |
| Non-living Thing | An object that does not perform life processes. |
| Growth | Permanent increase in the size of an organism. |
| Nutrition | Process of obtaining and using food. |
| Respiration | Process of releasing energy from food. |
| Excretion | Removal of waste materials from the body. |
| Reproduction | Production of young ones of the same kind. |
| Stimulus | Any change in the surroundings. |
| Response | Reaction of an organism to a stimulus. |
| Germination | Development of a seed into a seedling. |
| Life Cycle | Different stages in the life of an organism. |
Characteristics of Living Organisms
All living organisms possess certain common characteristics that help us distinguish them from non-living things.
- Need food for energy.
- Grow and develop.
- Respire continuously.
- Remove waste materials.
- Respond to changes in the surroundings.
- Reproduce their own kind.
- Show movement.
- Have a definite life span.
Living and Non-living Things
The following table highlights the major differences between living and non-living things.
| Living Things | Non-living Things |
|---|---|
| Grow naturally. | Do not grow naturally. |
| Respire. | Do not respire. |
| Need food. | Do not need food. |
| Respond to stimuli. | Do not respond. |
| Reproduce. | Cannot reproduce. |
Life Processes
Life processes are the basic activities performed by all living organisms to survive.
| Life Process | Function |
|---|---|
| Nutrition | Provides energy and nutrients. |
| Respiration | Releases energy from food. |
| Growth | Increases size and development. |
| Excretion | Removes waste materials. |
| Reproduction | Produces young ones. |
| Response | Helps organisms react to changes. |
Seed Germination
Germination is the process by which a seed develops into a young plant under suitable conditions.
Conditions Required
- Water
- Air (Oxygen)
- Suitable Temperature
Note: Most seeds do not require sunlight for germination, but sunlight is necessary after germination for healthy growth.
Life Cycles
Every living organism passes through different stages from birth to death.
| Organism | Life Cycle |
|---|---|
| Flowering Plant | Seed → Seedling → Adult Plant → Flower → Fruit → Seed |
| Mosquito | Egg → Larva → Pupa → Adult |
| Frog | Egg → Tadpole → Froglet → Adult Frog |
Movement in Living Organisms
Movement is an important characteristic of living organisms.
- Animals move from one place to another.
- Plants also show movement, although they remain fixed in one place.
- Plant shoots grow towards light.
- Roots grow downward into the soil.
- The touch-me-not plant folds its leaves when touched.
Response to Stimuli
Living organisms respond to changes in their surroundings.
| Stimulus | Response |
|---|---|
| Light | Plant shoot bends towards light. |
| Touch | Touch-me-not folds its leaves. |
| Heat | Animals move to cooler places. |
Important Scientific Terms
Remember the following scientific terms for examinations.
| Scientific Term | Meaning |
|---|---|
| Organism | A living thing. |
| Embryo | The young developing plant inside a seed. |
| Seedling | A young plant after germination. |
| Tadpole | The larval stage of a frog. |
| Larva | An immature stage in the life cycle of some insects. |
| Pupa | The stage between larva and adult mosquito. |
| Stomata | Tiny pores on leaves for exchange of gases. |
Important Facts
Remember these important facts for examinations.
- Living organisms perform life processes.
- Growth alone is not enough to identify a living organism.
- Plants also respire and respond to stimuli.
- Water, air, and suitable temperature are necessary for seed germination.
- Sunlight is generally not required for germination but is essential for plant growth.
- Mosquitoes and frogs undergo different stages in their life cycles.
- Every living organism has a definite life span.
- Respiration takes place throughout life.
- Plants prepare their own food through photosynthesis.
- All living organisms eventually die.
