Growth is maturing. Growing is something that you are doing all the time without even having to think about it. You grow a little bit taller every day, although you may not notice it. Over time you will have changed from a child into an adult. But humans are not the only living organisms to grow - animals and plants do too. You may have seen your pet change from a small puppy into a fully grown dog. It's easy to see plants growing - plant some seeds and, before long, they'll have roots and stems.

1.
Which of the following is not made up of cells?
A rose
A marble statue
A piece of absorbent cotton
A melon
Marble is made of tiny particles, not cells
2.
In order to see most cells, what must you use?
A microwave
A telescope
A microscope
A mirror
Only a few cells are large enough to be seen with the naked eye
3.
Which of these objects is not made of materials which were once alive?
A wooden spoon
A copper kettle
Leather gloves
A woolen coat
Wool and leather come from animals and wood comes from trees - these materials come from living organisms
4.
In order to grow well, what do plants need?
Water only
Light only
Light, water, warmth and carbon dioxide
Plant food and soil only
Minerals from the soil help plants to grow as well as possible
5.
Which of the following living organisms grows?
A chick
A runner bean plant
An adult human
All of the above
All living organisms grow! Growth is one of the life processes. Adults continue to grow, hair and nails for example - they just don't (usually) grow taller!

Coconut palm
Rabbit
Snake

8.
What tiny things are living organisms made from?
Cells
Plants
Microorganisms
Minerals
All living organisms are made up of cells. Even once-living materials such as wood, wool or leather are still made up of cells
9.
Living organisms grow by producing what?
Cells
Blood
Energy
Food
Cells are also produced to repair a living organism when it has been injured or damaged
