State a benefit of phototropism
It allows the plant to make more food
State a benefit of geotropism
It makes sure that the roots find water and minerals in the soil and that the plant is well anchored
List the two tissues used to transport food and water in plants
Xylem - Water and minerals
Phloem - Food (starch and sugar)
Where are the xylem and phloem tissues in the plant?
The vascular bundles (veins) on the leaf
What is transpiration?
This is the loss of water from the leaves of plants
What are stomata?
