Root tip practical

Dr Simon Fox takes you through the isolation and staining of a root tip, looking at the cellular structures under a microscope.

Did you have a discussion of that practical ,plzz

[@JanrickInchocoofficial]

sorry for asking. i want to ask if those images shown are the actual images of the sample he prepared.

[@schoolofbiomedicalsciences1348]

Hi Janus, Simon probably used stock images from an online source as the microscope he is using has no capacity for taking digital images of that quality.

Hı , What is the name of the blue solution you pour into the onion root tissue?

[@schoolofbiomedicalsciences1348]

Hi Selda, We are using acetic orcein.

What is the spelling of the end if the root tip. Didn't quite hear it

[@schoolofbiomedicalsciences1348]

Could you give me a rough idea of when Simon says this?

[@ellahafrikah1]

​@@schoolofbiomedicalsciences13481:13 the aethecal end of the root tip, that's what I hear him say but I'm not sure. The part where he grinds it on the slide.

[@schoolofbiomedicalsciences1348]

He says: "We gently apply pressure to the apical end of the root tip.."

I thought you were Simon Pegg in the thumbnail 😅

[@schoolofbiomedicalsciences1348]

We couldn't get Simon Pegg so opted for Simon Fox as he is cheaper (read: free!)!
