AS Biology - water pathways through a plant

A Level Biology, AS level. Topic - Plant transport. Description of movement of water from soil to xylem, through the endodermis and casparian strip, by the apoplast and symplast pathways.

Awesome!
I didn't understand the casparian strip part in the Raven biology of plants and this video really Helped me. Thanks!

[@JoPhillipsBiology]

I’m glad it’s helped! I hope you can help me out by subscribing!

[@deepakagrawal1205]

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.

You’re amazing, better than my book with this part

Oh thank you very much this was very helpful and your tellings are really nice!

[@katsokgwefane1980]

do all cells that make up the endodermis have the casparian strip?

[@kipropanthony1956]

Blessings to you

THAT'S RLY HELPFUL!!! TYSM. : )

Might be a stupid question but why does water never travel around the outside of the casparian strip?

[@progamers..1778]

Thanks ma'am

[@saiguynospy]

very cool

[@juwitasitanggang5650]

Thank you

[@deepakagrawal1205]

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.

Could you please explain how the casparian strip protects the plant against pathogens? Thanks

[@CS__NguyenangucHuy]

Of cells doesn't allow

Pathogens

[@yumnamukhtar366]

Do you still need the answer?

[@yumnamukhtar366]

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 :)
