Same dude! I couldn't understand it in the my primary textbook so I refered to Raven Johnson and to my surprise I still couldn't get the perfect grasp of it. This video is fab.
Okay so what's happening is that, In the apoplast pathway, the water only has to cross cell wall, and then from one cell wall to the other it travels, until it reaches the casparian strip. Cell wall is permeable, so it will allow, all pathogens, ions, minerals and nutrients through (basically the cell wall, has no guards to control what can or can not enter). But casparian strip forces the water to pass a semi-permeable membrane, which is the cell membrane located inner to the cell wall. The cell membrane can control what enters the cell, so if it detects pathogens, or any harmful ions, those will not be allowed to enter and eventually diffuse out of the cell wall. Hope that helped :)
Hello ma'am, Thank you for this great video and being so kind to the students by explaining everything so beautifully. QUERY- At 5.45, you said that water enters the root through diffusion. This has confused me as in the texts we follow, it says that water enters the root through osmosis. Request you to please clear this doubt. Thank you.
This definitely cleared a lot of my doubts, thank you so much for it 😄. But one of doubts remain that Why do Passage Cells(non-suberinised) exist in endodermis? Wouldn't it disrupt the whole process? Water can reach the space between Cell Wall and Membrane, via Apoplast pathway, of Passage cells.
Yes, sorry, I'm not using professional equipment and sometimes it seems to go too quiet. I'll try to adjust it. Please subscribe if you haven't already :-)
Awesome!
I didn't understand the casparian strip part in the Raven biology of plants and this video really Helped me. Thanks!
I’m glad it’s helped! I hope you can help me out by subscribing!

You’re amazing, better than my book with this part
Classroom learning is everywhere,access to learning is made simpler.
THANKS A TON!! i couldn't find a video on this topic until yours..thank you so so much :))
I'm pleased it was useful! Please subscribe if you haven't already :-)
Mam you are my best teacher
such a beautiful illustration❤
Incredible explanation
Oh thank you very much this was very helpful and your tellings are really nice!
Mam you r amazing better than the ssc II book b/c you made it clear the 2 pathway of watwr and how does its importance.
Doubts were cleared!
Thank you so much
Could you please explain how the casparian strip protects the plant against pathogens? Thanks
Of cells doesn't allow
Pathogens
Do you still need the answer?

@@yumnamukhtar366 Hi, thanks for the reply. It does definitely help 🙂
Might be a stupid question but why does water never travel around the outside of the casparian strip?
Thank you so much!
Blessings to you
do all cells that make up the endodermis have the casparian strip?

THAT'S RLY HELPFUL!!! TYSM. : )
What of vacuolar pathway
The space in which water pass through in apoplast is called
very cool
Can you please make videos on translocation?
Yes I will, eventually!
Tank you
Wow very smart boy dis is
Mashallah

Thanks ma'am
Thank you
You're welcome!
😍
Such a great explanation! I would've appreciated a higher volume though
