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.

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

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

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

Which of these objects is not made of materials which were once alive?

A wooden spoon

When they don't get enough rest

Living organisms only stop growing at death

Which living organism needs to shed its skin regularly as it grows?

Human

Coconut palm
