Which describes the light-dependent stage of photosynthesis?
(Select all that apply.)
A-Photosynthetic pigments absorb energy from light.
B-Hydrogen ions (H+) are moved against their concentration gradient.
C-Carbon dioxide is incorporated into a preexisting sugar molecule.
D-Water is split, which produces oxygen.

Answer ,A-Photosynthetic pigments absorb energy from light,

D-Water is split, which produces oxygen

Explanation:

Water is split, which produces oxygen.

Light dependent reaction uses energy from sunlight that is absorb by the chlorophyll pigment of the leave. This is is what is used in light dependent reaction where water is split into hydrogen and oxygen. The oxygen is released into the atmosphere and the hydrogen with NADP produced NADPH , ATP is ls also formed from the reaction of ADP+P during light independent reaction which is harness to produce sugar.

ATP- Adenosine tri-phosphate

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
