Tissue in plants Flashcards
What are two types of tissue in plants?
epidermis tissue - adapted to cover plant surfaces
vascular tissue - adapted for transport of water and nutrients
How is the epidermis specialised to perform its function?
epidermis is a single layer of closely packed cells covering the surfaces of plants
covered by a waxy, waterproof cuticle to reduce the loss of water
stomata, formed by guard cells can open and close and are present in the epirdermis
How is xylem tissue adapted to perform its function?
type of vascular tissue responsible for transport of water and minerals throughout plants
the tissue is composed of vessel elements, which are elongated dead cells
the wall of these cells are strengthened with a waterproof material called ligni, which provide structural support for plants
How is ploem tissue adapted for its function?
vascular tissue responsible for the transport of oranic nutrients, particularly sucrose from leaves and stems where it is made by photosynthesis to all the parts where it is needed
composed of columns of sieve tube cells separated by perforated walls called sieve plates
