Plant Tissues And Organs Flashcards
Explain the role of xylem in plants?
To carry water mineral ions from the roots to the stem and leaves
What does translocation mean?
Transport of dissolved sugars
What are Vascular Bundles?
Groups of xylem and phloem tissues in a plant
What does differentiation mean?
Changing to do a function
Explain why translocation is essential for a plant’s survival?
to carry out respiration
Explain the role of phloem in the plant?
To Transport dissolved sugars
What is a meristem cell?
A cell that can differentiate to be any other cell in the plant
The top and bottom of Xylems have no what?
Cell walls
Name three Xylem traits?
They are dead, hollow and contain no cytoplasm and are strengthened by lignin
Name 3 phloem traits?
They are living they have few sub cellular structures so substances can pass through easily and substances can move in both directions
Where are sieve plates located and what do they have to allow cell sap to flow through?
At the bottom/top of the phloem cells and they have pores to allow cell sap to flow through
