Transpiration & translocation Flashcards
1
Q
what is translocation?
A
the movement of organic nutrients, particularly sugars produced during photosynthesis
2
Q
what is transpiration?
A
process where water is evaporated from the plant’s surfaces, primarily the leaves
3
Q
what factors can affect the rate of transpiration?
A
temperature, humidity, wind, light intensity, and the surface area of leaves
4
Q
what is the primary function of xylem tissue?
A
- transports water and dissolved minerals from the roots to the leaves and other parts of the plant
- also provides structural support due to its rigid, lignified cell walls
5
Q
what roles do phloem tissues play in a plant?
A
- transport organic nutrients (mainly sugars) to other parts of the plant
- consist of living cells, including sieve-tube elements
