Key Concept: All living organisms share the same eight life processes.
Section A: Recall
1. List the eight characteristics of living organisms. [8]
2. Match each description to the correct characteristic. [8]
a) Releasing energy from food in cells
b) Keeping internal conditions stable
c) Producing offspring
d) Increase in size or complexity
e) Removing waste products such as $CO_2$ and urea
f) Changing position or moving parts of the body
g) Taking in materials for energy or growth
h) Detecting and reacting to changes
Section B: Examples
3. Give one example for each characteristic. [4]
a) Nutrition
b) Respiration
c) Excretion
d) Response
4. Explain the difference between respiration and breathing. [2]
Section C: Application
5. Explain why growth and development are not the same as reproduction. [2]
6. Identify the characteristic shown in each scenario. [4]
a) A plant bends towards a light source
b) A lizard lays eggs
c) A person sweats on a hot day
d) A seedling grows taller each week
Total marks: 28
Mark Scheme
1. Nutrition, respiration, excretion, response, movement, homeostasis (control of internal conditions), reproduction, growth and development [8]
2. a) Respiration b) Homeostasis c) Reproduction d) Growth and development e) Excretion f) Movement g) Nutrition h) Response [8]
3. Accept any correct examples for each characteristic [4]
4. Respiration is the chemical release of energy from food in cells; breathing is movement of air into and out of lungs [2]
5. Growth/development change the size or complexity of one organism; reproduction produces new offspring [2]
6. a) Response b) Reproduction c) Homeostasis d) Growth and development [4]
