translocation and transpiration Flashcards
1
Q
In plants water is used for
A
turgidity
photosynthesis
dissolving and transporting mineral ions
Chemical reactions
2
Q
why do plants need mineral ions and what for
A
magnesium- chlorophyll
calcium- calcium pectate (middle lamella)
nitrogen- needed for DNA, amino acids (growth)
3
Q
explain capillary action
A
water molecules are attracted to each other due to their dipole nature this can, in small spcaes cause the water to be drawn up
4
Q
What happens to glucose before being transported
A
It gets converted into sucrose because it is more efficient to transport a disaccharide
5
Q
Why do plants need sugar (6)
A
respiration
energy store (starch)
cellulose
synthese into amino acids
amino acids are used to make proteins
