transport in cells Flashcards
how are root hair cells adapted
large surface area
lots os mitochondria for energy
what are root hair cells characteristics
long thin hairs that penetrate through the soil
what is root hair cells function
absorb water and mineral ions
water absorbed by osmosis
mineral ions absorbed by active transport
what are phloems made from
elongated living sells
what is a phloems function
transports food (mainly sucrose)
what makes a phloem different from a xylem
phloem have end walls
made of living cells
transport goes in both ways
what is the xylems function
to transport water and mineral ions from root to stem to leaves
what is the xylems characteristics
strengthened with lignin
made of dead cells
transpiration is ……
the movement of water out of plants leaves
translocation requires…….
energy and takes place in the phloem
