Name the special cells available in plants for the transport of water and food.
Xylem and Phloem
The plant tissue that carries food materials DOWNWARD from the leaves to the rest of the pant is the ______.
phloem
Vascular bundles are made up of _______ and _______.
xylem - phloem
Movement of sucrose and amino acids in phloem; from regions of production (sources) to regions of storage or to regions of utilization in respiration or growth. What term to call that process?
Translocation
An increase in wind or temperature will ________________ transpiration
Increase
Any 2 functions of Xylem
Food storage, Carrier of water and mineral, Mechanical support.
How do water enter the roots from the soil? what is the term for the process?
Osmosis
What is the function of Xylem fibres?
To provide mechanical support.
What is responsible for Translocation in plants, the xylem or the phloem?
the phloem
Transpiration is the _______ of water at surfaces of the mesophyll cells followed by loss of water vapour from plant leaves, through _______.
evaporation - stomata.
What is the function of stomata?
Functions as a gate for the entry and exit of the gases and plays an important role in transpiration.
The 3 limiting factors that affect the rate of TRANSPIRATION are temperature, humidity and light intensity. True or false?
True

polymers that form key structural materials in the support tissues of most plants.
What do you call the vessel that transports nutrients?
Phloem
Rate of transpiration decreases with the increase in the humidity. State if it is True or False.
True
Movement in the phloem tissue goes in one direction. True or false?
