In stems, auxin accumulation will occur on the side that is away from the light source, and cell elongation will occur on the opposite side.

In stems, auxin accumulation and cell elongation will occur on the side that is away from the light source.

In stems, auxin accumulation will occur on the side that is near the light source, and cell elongation will occur on the opposite side.

In stems, auxin accumulation and cell elongation will occur on the side that is near the light source.

Answer 1

1: the concentrations of ethylene spray
2: In stems, auxin accumulation and cell elongation will occur on the side that is away from the light source.

Answer 2

Kid who hates Fortnite was wrong about the stem question, here is the full quick check test.

1: reproduction without another parent.
2: can help a species better adapt to environmental changes.
3: haploid gametophyte
4: the concentrations of ethylene spray
5: In stems, auxin accumulation and cell elongation will occur on the side that is away from the light source.

Answer 3
