Auxins are a group of plant hormones that promote plant growth. For example, when a moose eats the top of a small aspen sapling, an auxin hormone is released by the plant and it travels to the meristematic cells (growing cells) at the ends of branches, where it causes those branches to grow more rapidly. Hormones in the auxin group are usually found in a charged, hydrophilic form.
The herbicide 2,4-D (2,4-Dichlorophenoxyacetic acid) is a synthetic auxin that is applied to broadleaf plants and when it enters plant cells, it causes uncontrolled, unsustainable growth that results in plant death.
Sodium azide is a compound that researchers can apply to cells and it prevents cells from making ATP. When researchers applied sodium azide to plant cells they found that the cells were then unable to absorb 2,4-D.
How does 2,4-D enter plant cells? Describe the steps of the process that is being used to move 2,4-D into cells, and explain why you think this is correct.
