Life Processes

By Ewan

Introduction

MRS GREN is an easy way to remember the seven life processes. They are: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition. The seven life processes are what builds up a ‘living thing’.

Growth

Seed to flower, baby to adult, cub to tiger, altogether Growth is a very important life process. All living things grow. In life growth important for living things to defend and to look after themselves. As well as humans, plants need to grow as well because if somebody tramples on a seed then it most likely will not grow but if it’s a fully grown tree then it will have grown strong enough to survive from it.

Movement

Movement is very important because if you can’t move then you won’t be able to escape from danger. Movement is an important life process so animals can keep fit and protect themselves from anything chasing them. Did you know that plants move their leaves towards the sun as the plants grow?

Sensitivity

Sensitivity is your senses: smell, taste, hear, sight, and touch. “hearing” is a great sense to locate animals or anything loud. ‘sights’ also an extremely good sense for observing things such as dangerous animals, plants, danger and food. ‘Smell’ is also a good sense because it can alert us to dangers like a fire, or a delicious meal.

Excretion

Excretion is when living things let out all of the toxic waste that they no longer need. It’s also when you breath out carbon dioxide which carries a out a lot of toxins as well. On the other hand plants excrete by shedding their leaves. Did you know that plants excrete more than humans.

Respiration

Respiration is breathing. To breath is one of the obvious things that classifies a living thing to a non living object. A living thing breathes in oxygen and breathes out carbon dioxide also known as ‘co2’, however plants do the opposite. They breath in carbon dioxide and breath out oxygen.

Nutrition

Nutrition is what living things eat and drink. It is an important life process to keep a living thing healthy, fit and strong. If living things do not eat then they will die of hunger, on the other hand if you don’t drink then living things will get dehydrated and die.

Reproduction

Reproduction is the one of all of the seven life processes that is important. Reproduction is something that carries on the species of animal or plant.

Conclusion

Now that you know all of the seven life processes then you can tell other people about it and have it in the back of your mind. Once again the seven life processes are: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition.
