it to grow <a href="/wiki/Cell" title="Cell">cells</a> from <a href="/wiki/Animal" title="Animal">animals</a>, <a href="/wiki/Fungus" title="Fungus">fungus</a>, and <a href="/wiki/Disease" title="Disease">diseases</a> so they can study them. They are usually made of <a href="/wiki/Glass" title="Glass">glass</a> or <a href="/wiki/Plastic" title="Plastic">plastic</a>. The glass ones can be used again if they are heated at 160°<a href="/wiki/Fahrenheit" title="Fahrenheit">F</a>. Sometimes people fill them with <a href="/wiki/Agar" title="Agar">agar</a>, which helps cells grow. These are called 'agar plates'. Many people use them in <a href="/wiki/Science" title="Science">science</a> classes at <a href="/wiki/School" title="School">school</a>. They have lids so <a href="/wiki/Pathogen" title="Pathogen">germs</a> in the air can not get into them, or <i>contaminate</i> them, and ruin the experiment. </p> <div class="boilerplate metadata plainlinks" id="stub"><span typeof="mw:File"><a href="/wiki/File:Science-symbol-2.svg" class="mw-file-description"><img alt="" src="//upload.wikimedia.org/wikipedia/commons/thumb/7/75/Science-symbol-2.svg/30px-Science-symbol-2.svg.png" decoding="async" width="30" height="30" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/75/Science-symbol-2.svg/45px-Science-symbol-2.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/75/Science-symbol-2.svg/60px-Science-symbol-2.svg.png 2x" data-file-width="87" data-file-height="87" /></a></span> <i>This <a href="/wiki/Wikipedia:Stub" title="Wikipedia:Stub">short article</a> about <a href="/wiki/Category:Science_stubs" title="Category:Science stubs">science</a> can be made longer.
