biology textbook ncert on page 180 fig answer is b to a ryt?
Concentration of minerals in soil < Concentration of minerals in roots. This is wrong the greter than sign must be in opposite direction.
what would be the pressure potential of a flaccid cell?
last point of (relationship of transpiration and photosynthesis)is not cleared............please explain it in easy terms.
please explain the following terms and clearly point out the diff between them
Transpiration is a necessary evil. It is necessary..understood...but how it is an evil?
