plant cell organisation Flashcards
what is the epidermal tissue used for
covers the whole plant which reduces the loss of water
what is the palisade mesophyll
top part below epidermal tissue, this is the part of the leaf at which most photosynthesis happens
what is the spongy mesophyll tissue used for
contains big air spaces to allow gases to diffuse in and out of cells
where is the meristem tissue found
shoots and roots of growing plants
what does the meristem tissue do
able to differentiate into lots of different types of of plant cell, allowing the plant to grow
what do phloem tubes transport
foods (mainly dissolved sugars)
which direction do phloem tubes go
both ways
what are phloem cells made out of
elongated living cells with small spores in the end of walls
what is the xylem tube made out of
dead cells joined end to end with no end walls between them and a hole in the middle
what do xylem tubes carry
water and mineral ions
where are the mineral ions carried in the xylem tube
from the roots to the stem and leaves
what is the movement of water from the roots to the leaf (exiting) called?
transpiration tube
