Biology B2 - Root hair cells - structure and function

Question 1

what are features of the root hair cell ?

Answer 1

They have a large surface area that extend from the root epidermis . It extends the water and ion contact with the soil.

The membrane contains protein channels and carrier proteins this means it helps diffusion and active transport for essential ions.

It allows substances to pass through maintain cell health.

Question 2

what is the structure of a root hair cell ?

Answer 2

Partially permeable membrane , It regulates osmosis to draw in water from the soil , prevents excessive ions loss from the cell.

Mitochondria , root hair cell have mitochondria to supply energy , Energy powers active transport allowing uptake of nutrients.

Question 3

what is there a thin wall in a root hair cell ?

Answer 3

The thin wall reduces the distance water and ions must travel.

Question 4

important fact about root hair cells

Answer 4

Short diffusion distance speeds up the absorption process .

Question 5

important fact about root hair cells

Answer 5

Root hair cells are constantly replaced ensuring fresh cells.

Question 6

why are there soil conditions in root hair cells ?

Answer 6

The soil conditions help adapt to changing environmental conditions.

Question 7

what are Root hair cells specialised for ?

Answer 7

They are specialised for rapid and efficient absorpotion.

Question 8

Name a structure of the Root hair cell ?

Answer 8

They have a large surface area for contact with soil.

Question 9

why are there membrane proteins in the root hair cell ?

Answer 9

Membrane proteins for selective ion transport.

Question 10

why is there mitochondria in root hair cells ?

Answer 10

Mitochondria to power active processes.

Question 11

Another structure of the root hair cell ?

Answer 11

Thin walls in the Root hair cell for faster diffusion.
