Long can cover more distance

branched connections at their ends to connect other nerve cells and form a network

Question 2

Muscle cells

Answer 2

Their walls become thickened and woody. They therefore support the plant. made from lignin

carry water and mineral ions from roots to stem and leaves

made from dead cells

Question 4
