Question

Explain in brief.
Concentration of minerals nutrients elements
is higher inside the root hairs than in the surrounding soil.How do roots take them in from the soil?

Answer 1

what do you think & already know about this?

Answer 2

Osmosis.

Answer 3

define it

Answer 4

it si the diffusion of water moleclues across a semi permeable membrane from a mre dil sol to a less dil sol.

Answer 5

in other words
from high conc to low cons, down conc gradient

Answer 6

but
look at what the q is saying

Answer 7

it says nutrient conc in roots is higher than in soil
BUT you roots gotta still take up nutrients from soil

Answer 8

in other words, the flow will be against concentration gradient, from low- soil, to high - root

Answer 9

this type of transport is called - active transport & uses energy from ATP hydrolysis

Answer 10

makes sense?

Answer 11

Yes.

Answer 12

So is it Endosmosis?

Answer 13

endosmosis?

Answer 14

are u combining endocytosis & osmosis?

Answer 15

idk that term was in/on my notes which my teacher gave me.

Answer 16

hmm its first time im hearing it
i'll check out

Answer 17

active transport as i said
endosmosis - is to do with fluid, when we talk about nutrients- we are talking about ions, some carbohydrates or proteins if there are

Answer 18

i mean in plants
mostly ions

Answer 19

osmosis is to do with water but we deal with nutrients

Answer 20

there are specific protein channels for them

Answer 21

What is that?

Answer 22

@Somy

Answer 23

hmmm there are 3 types of transport systems
passive diffusion: osmosis (deal with water), diffusion (the rest, gases etc)
facilitated: also a type of passive diffusion, from high to low, but involves protein channels, & is to do with charged/polar for example: ions
active transport: transport from low to high conc using energy

Answer 24

So my answer is active transport?

Answer 25

yeah - thats from what i have learnt form highschool + uni
i never heard of endoosmosis or exoosmosis

Answer 26

Thanks.

Answer 27

no problem :)
