The picture below shows a change in turgor pressure called wilting in a plant. Which statement best describes what has happened between picture A and B?
a)
Water increased the turgor pressure in the cells of the flower.
b)
Water entering and leaving the cells of the flower at equal rates kept turgor pressure equal.
c)
Lack of water in the soil decreased the turgor pressure in the cells of the flower.
d)
Lack of sunlight on a cloudy day caused the flower to lose turgor pressure.

The plant is responding to the heat of the lamp growing towards it.
b)
The plant is leaning to the lamp to get more carbon dixiode.
c)
The plant is responding to the stimulus of sunlight.
d)
The plant is responding to the lamp because Journee water it everyday.
