plant cell organisation Flashcards
what are plants made off
organs like stems, roots and leaves
what to plant organs work together to make
organ systems
what are plant organs made off
tissue
what are examples of plant tissues
epidermal tissue
palisade mesophyll tissue
spongy mesophyll tissue
xylem
phloem
meristem tissue
what is epidermal tissue
it covers the whole plant
what is palisade mesophyll tissue
its the part of the leaf where photo synthesis happens
what is spongy mesophyll tissue
contains big airspaces to allow gases to diffuse in and out of the cell
what are xylem and phloem
they transport water, mineral ions and food
what is meristem tissue
it’s found at the growing tip of short roots
and differentiate into different types of plant cell
what is the epidermal tissue covered in
waxy cuticle
helps reduce water loss
what is the adaptation of upper epidermis
it’s transparent so light can pass through
what is the adaptation of the palisade layer
has lots of chloroplasts
is at the top of the leaf so it gets more light
what is the adaptation of the xylem and phloem
its from a network of vascular bundles
deliver water and other nutrients to the entire leaf
what is the adaptation of the tissues
efficient for gas exchange
