Chapter 4.7 Transport systems in plants Flashcards
What does phloem tissue transport?
The phloem tissue transports the sugars made by photosynthesis from the leaves to the rest of the plant.
What is phloem?
Phloem is a living tissue - the phloem cells are alive.
What is the movement of dissolved sugars from the leaves to the rest of the plant known as?
This is known as translocation.
What does xylem tissue transport?
The xylem tissue transports water and mineral ions from the soil around the plant to the stem and the leaves.
Which part of the plant does the xylem make up?
The xylem makes up the bulk of the wood.
What part of the plant does the phloem make up?
The phloem is found in a ring just underneath the bark.
Why do plants have separate transport systems?
Plants need vascular bundles for transport the food, minerals and water. When leaves do photosynthesis and form food, then this cannot directly get by the roots. So phloem is used for transporting the food from leaves to roots. Hence plants need transporting system.
