Hey future biologists! 👋 You ready to dive into the microscopic world of cells? Today, we&#39;re gonna talk about how to identify phases of mitosis using a root tip squash experiment! Yep, you heard me, we&#39;re making a cell smoothie 🥤 and looking at it under a microscope 🔬. Don&#39;t worry, it&#39;s not as gruesome as it sounds. Let&#39;s roll!

Mitosis is the process where a single cell divides into two identical daughter cells. It&#39;s like cell cloning! This is super important for growth, repair, and general maintenance of our bodies. Imagine you scrape your knee; mitosis is what helps you heal.

<ul>
	<li>
	Ethanol Fixation: When you get a tattoo, the ink needs to stay, right? In a way, fixation in biology is like that, making sure the cell structure remains unchanged.
	</li>
	<li>
	Hydrochloric Acid: Ever tried to dissolve something tough like, let&#39;s say, a marshmallow in hot chocolate? Hydrochloric acid works on cell walls the same way hot chocolate works on marshmallows. It loosens them up! 🍫☕
	</li>
	<li>
	Toluidine Blue Stain: You know how detectives use UV light to see things otherwise invisible? This stain works like that but for DNA.
	</li>
</ul>

Understanding mitosis is critical for areas like cancer research. Cancer is basically cell division gone wild, so getting the 411 on normal cell division helps us figure out what&#39;s going wrong in cancer cells.

<ul>
	<li>Always wear eye protection when dealing with hydrochloric acid.</li>
	<li>Gloves are a must for handling the stain.</li>
</ul>

<ul>
	<li>Mitosis is like cell cloning and super important for growth and repair.</li>
	<li>The root tip squash experiment involves growing garlic roots, fixing them, loosening cell walls, staining, and finally squashing them for microscopic observation.</li>
</ul>

So, there you have it! You&#39;re now all set to dive into the world of cells like a pro. Happy studying, and may the mitotic force be with you! 🌟🔬

Questions? Thoughts? Hit me up! ✌️

<ul>
	<li>
	Start the Root Growing: Grab a garlic clove (yup, the stuff in garlic bread 🍞) and suspend it in water using toothpicks for at least 3 days. You&#39;re looking for roots to grow.
	</li>
	<li>
	Fixation Time: Cut those newly grown roots and fix them in a mix of 70% ethanol and a smidgen (1 part) of pure ethanoic acid for 24 hours. This basically &#39;freezes&#39; the cells, so they stay put.
	</li>
	<li>
	Acid Bath 🛁: Get those roots into 0.1 moldm&ndash;3 hydrochloric acid at 40&deg;C for 5 minutes. Put on eye protection&mdash;this stuff isn&#39;t lemonade. 🍋 This loosens up the cell walls so they&#39;re easier to squash later.
	</li>
	<li>
	Get the Color In: Cut off 20-30mm of the root tips and dunk them in 1% toluidine blue stain. Gloves on, folks! This stain is gonna make the DNA in the cells stand out like neon signs at a night market. 🌃
	</li>
	<li>
	Smash &#39;n Look 👀: Rinse off the stain and gently squash the root tips under a cover slip. Start spying on those cells using a microscope. First use low power, then crank it up to medium.
	</li>
</ul>
