Revision Notes for Class 10 Science
Chapter 5 - Life Processes
The study of living things is referred to as biology. Organisms refer to all living things, which
includes both plants and animals. However, seven life processes influence how we determine
if something is alive or not. If anything is alive, it will go through the 7 life processes listed
below.
1. Movement
• Animals and plants both have the ability to move around. Plants are rooted and grow at
a leisurely pace.
• Their roots go deeper into the soil, while their stems reach for the sun. Animals, on the
other hand, can shift their entire bodies swiftly.
• They have the ability to migrate in pursuit of food, shelter, or safety.
2. Respiration
• The process of getting energy from the food we eat is known as respiration.
• All living things need to breathe in order to develop, replace worn-out parts and move.
Respiration occurs in the cell's mitochondria.
3. Sensitivity
• All living things are sensitive, which means they are aware of changes in their
surroundings.

, • Heat, light, sound, touch, and chemicals with taste and smell are all stimuli that animals
respond to swiftly.
• Plants, on the other hand, appear to be less sensitive and respond more slowly.
4. Growth
• Growing is a process that occurs in all living creatures. Plants keep growing for the rest
of their lives.
• When animals reach adulthood, they stop growing.
• Even when development ceases, an animal's body continues to be replenished with
materials obtained from its food.
5. Excretion
• All living things produce waste products, which can be either useless or hazardous to
them and hence must be disposed of.
• The process of excretion is the removal of metabolic waste.
• Plants retain waste substances in their leaves, and as the leaves fall off, the garbage is
eliminated.
• Other waste substances exit the body in urine and sweat, and animals breathe out waste
carbon dioxide.
Note: Egestion, not excretion, is the process of getting rid of faeces or undigested food.
