Plant Tissues Flashcards
(10 cards)
What are the three types of plant tissues
Dermal
Vascular
Ground
Explain the role of the dermal tissue and where it’s located
Also provide an example.
Is a one cell layer thick tissue that protects the plant from disease
It is on the outside of the plant
An example would be a cuticle
Explain what a cuticle is and its function
A waxy substance produced and discharged by cells in the leaves and stems
It coats the leaf and reduces water loss essentially protecting it
What is the vascular tissue and its function
What two things does it consist of
Tissue responsible for transport in plants between the roots and shoots
It consists of the:
Xylem
Phloem
What is the structure and function of the xylem
Thick-walled tubes, moves water and dissolved minerals from roots up the stem to the leaves
What is the structure and function of the phloem
Formed of sieve tube cells and companion cells, transports dissolved sugars produced in leaves to other parts of the plant
What tissue are the xylem and phloem found in
The vascular tissue
What are sieve tube cells and companion cells
Sieve tube cells - cylinder like cells lacking a nuclei that allow the movement of phloem sap between cells
Companion cells - connect to the sieve tube and control the transport of sugar in the phloem
What is the structure and function of the ground tissue
Layer of cells found beneath the epidermis
Known as the bulk of the plant
What is the role of the ground tissue in the stems, roots, and leaves
Stems- provides strength and support
Roots- provides food and water storage
Leaves- where photosynthesis occurs
