Topic 2a - Tissues, organs and organ systems ( 6. plant cell organisation ) Flashcards
what are some example of plant organs
stems roots and leaves - work together to make organ systems (the plant) made of tissues
examples of tissues plant organs are made of…
epidermal tissue palisade mesophyll tissue spongy mesophyll tissue xylem and phloem meristem tissue
function + adaptation of epidermal tissue
covers the whole plant
covered with a waxy cuticle which helps to reduce water loss by evaporation
upper epidermis is transparent so that light can pass through easily
function + adaption palisade mesophyll tissue
where most of the photosynthesis happens
lots of chloroplasts. near to top of the leaf where they can get most light
function + adaptation of spongy mesophyll tissue
also in the leaf, contains big air spaces to allow gases to diffuse in and out of cells
function + adaptation of xylem and phloem
they transport things like water and mineral ions and food around the plant.
