This is the ability of living thing to move from one place to another in search of food , shelter and safety . Plants do not have the ability to move from one place to another because they are fixed rooted deep in one place and yet their roots move towards water and minerals while their shoot move towards sunlight ,




Plants take in carbon dioxide and release oxygen into the atmosphere, exchange of gases occurs through stomata.

Animals take in oxygen and release carbon dioxide into the atmosphere, which occurs through lungs, gills, skin, etc.




Nutrients are chemical substances that are readily available in food that make our body and bones strong. Plants need nutrients too .  Plants make their own food . The process whereby plants make their own food in the presence of sunlight is known as PHOTOSYNTHESIS . Plants have chlorophyll, which they use whenever they want to make their food. Animals are the heterotrophs, as they depend on plants for their food, either directly or indirectly.




This is the ability of living things to respond to internal or external stimulus . Living things have feelings .Plants show the response to stimuli like touch, light, though are less sensitive due to the absence of the sense organs. They have proper nervous system and response to any stimuli in a fraction of seconds, so they are regarded as highly sensitive. Animals are the living organisms which feed on the organic material and are known to have a specialized system in their body like the nervous system, reproductive system, sense organs, which make them unique from the other forms of life. Some plants are very sensitive to touch .




This is an irreversible increase in the size . weight or body of living things . All living things grow . An egg of a frog will first become a tadpole before it eventually develops into a frog . That is growth . The seeds of plants will sprout or germinate to become a fully grown crops that will bring forth another seeds , leaves and fruits . The growth of the plants takes place throughout the life, .




All living things pass out waste products. As a result of the many chemical reactions occurring in cells, they have to get rid of waste products which might poison the cells. Excretion is defined as the removal of toxic materials from the body of living things . Human pass out carbon dioxide from the lungs through the nostrils while plants pass out oxygen through the stomata




Reproduction is necessary for the continuity of life . It is the process where living things make little ones that look like their parents . Like a bay cow is called a calf. a baby dog is called a puppy .

Reproduction of plants takes place asexually like by budding, vegetative methods, spores, wind, or through insects.Some lower animals like algae reproduce asexually while higher animals reproduce sexually.




This is an inevitable end of every creature as all living things will die and become non living things
