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 these objects is not made of materials which were once alive?
[ ] A wooden spoon
[x] 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
2. What tiny things are living organisms made from?
[x] 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
3. In order to see most cells, what must you use?
[ ] A microwave
[ ] A telescope
[x] A microscope
[ ] A mirror
Only a few cells are large enough to be seen with the naked eye
4. Which of the following living organisms grows?
[ ] A chick
[ ] A runner bean plant
[ ] An adult human
[x] 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!
5. Which of the following is not made up of cells?
[ ] A rose
[x] A marble statue
[ ] A piece of absorbent cotton
[ ] A melon
Marble is made of tiny particles, not cells
6. In order to grow well, what does the human body need?
[ ] Water and exercise only
[x] Food, exercise, water and rest
[ ] Food, vitamin tablets and medicine only
[ ] Food only
Without food, water and rest we would soon die
7. In order to grow well, what do plants need?
[ ] Water only
[ ] Light only
[x] Light, water, warmth and carbon dioxide
[ ] Plant food and soil only
Minerals from the soil help plants to grow as well as possible
8. Living organisms grow by producing what?
[x] Cells
[ ] Blood
[ ] Energy
[ ] Food
Cells are also produced to repair a living organism when it has been injured or damaged
9. Which living organism needs to shed its skin regularly as it grows?
[ ] Human
[ ] Coconut palm
[ ] Rabbit
[x] Snake
The outer skin of a snake is dead and cannot grow - as the snake grows, a new layer of skin forms underneath and the old skin is shed. Many insects regularly discard their exoskeletons for the same reason
10. When do living organisms stop growing?
[ ] When they reach a particular height
[x] When they die
[ ] When they are old
[ ] When they don't get enough rest
Living organisms only stop growing at death
