a) The characteristcs of a plant is similar to a car because a car needs petrol and air and a plant needsoxygen and the sun.
b) A car is not a living organism because it is a machine, if you hit a car, it will not hurt him because a car is not a living organism.
Activity 3
1 Some yeast, sugar and water are mixed in a test-tube. The
diagrams show the test-tube at the start and after one hour.
a Which process causes this change?
A growth
B irritability
C reproduction
(D) respiration
b Excretion, irritability and reproduction are characteristics
of:
A all animals and plants
B animals only
C plants only
(D) some animals and some plants only
c Which one of the following functions is carried out by green plants but not by animals?
A excretion
B growth
(C) photosynthesis
D respiration
d Figure 3 shows how fish react when the glass on one side
of an aquarium tank is tapped with a finger.
What characteristics of living organisms does this demonstrate?
A excretion and movement
B excretion and nutrition
C growth and irritability
(D) irritability and movement
2 Complete the passage below by choosing the words from this
list:
excretion growth irritability movement nutrition
organisms reproduction respiration
A Living things are often called ORGANISMS.
B All living things release energy from their food in a process
called EXCRETION, which happens inside their cells.
