- All the organisms perform some basic functions to keep themselves alive.
- The most important criterion to decide whether something is living or non- living is the movement.
- All the living things (which are alive) move by themselves without any external help.
- For example: jumping of frog, birds flying in sky, fish swimming in water shows movement of animal from one place to another
- In case of plants they remain fixed in the soil at a place, so they cannot move like animals from place to place.
- Movement is visible in their body parts such as leaves, flowers, shoots and roots.
- The plant parts move towards a stimulus such as sunlight, gravity or water, etc.
- For example, the shoot, the leaves and flower of a sunflower plant move by bending towards the sun so as to face the sunlight
What are Life Processes
- The basic functions performed by living organisms to maintain their life on this earth are called life processes.
- The basic life processes common in all the living organisms are: Nutrition and Respiration; Transport and Excretion; Control and Coordination (Response to stimuli); Growth; Movement and Reproduction.
Life Processes will Cover the following topics.
- Types of Nutrition
2.A. Nutrition in Human Beings
