cell specialisation

Question 1

example- muscle cells

Answer 1

function- to contract quickly
these cells are long (so they have space for them to contract) and contain lots of mitochondria to generate the energy needed for the contraction.

Question 2

another example- root hair cells for absorbing minerals and water.

Answer 2

root hair cells are on the surface of plant root cells which grow into long ‘hairs’ that stick out into the soil.
this gives the plant a big surface area for absorbing water and mineral ions from the soil.

Question 3

phloem- specialised for transporting substances

Answer 3

the phloem cells form tubes which transport substances such as food water around plants. to form tubes, the cells are long and joined end to end

Question 4

xylem- specialised for transporting substances

Answer 4

are hollow in the centre which have very few subcellular structures so that stuff can flow through them. they transport things like food and water through the plant.
