Many floating aquatic plants, such as water lilies, only contain chlorophyll in the top part of their leaves. In fact, the bottom part of a water lily is often purple because it lacks chlorophyll. This adaptation most likely occurs because
A.
nutrients are only absorbed by the top part of the leaf.
B.
water loss is reduced by having less chlorophyll.
C.
heat loss is reduced by having less chlorophyll.
D.
sunlight only hits the top part of the leaf.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
