Essay On Plant Hormones

1007 Words5 Pages
The article explores the possibility of plants that we consume such as vegetables, fruits or other edible plants, containing remaining hormones that may have both positive and negative impacts on our health. Recent studies have indicated that there may be a connection between our gut microbes stimulating the creation of molecules in response to the remnants of hormones in plant matter. Positive impacts look at ABA-rich foods as a way to protect against and fight off cancers cells, and also to regulate inflammation and blood glucose levels. Further research is need to figure out and come to a conclusion as to why certain hormones work to aid human health and others don’t. A possible explanation for some of the negative responses is probably…show more content…
Put simply, ABA tells the stomata to close when there isn’t enough soil water for transpiration to occur. When ninety percent of the plant’s water is lost through the stomata, the turgid guard cells become flaccid, causing the stomata to close. The process behind this is ABA binds to receptors on the surface of the plasma membrane of guard cells. The receptors are then activated, resulting in various pathways connecting to create a couple of occurrences: a rise in Ph in the cytosol and the transfer of calcium ions from the vacuole to the cytosol. What these changes effect is the loss of negatively-charged ions, particularly nitrate and the chloride ion from the cell, as well as the positively-charged potassium ion. After losing the solutes, cytosol lessens the osmotic pressure and result in the loss of turgidity. The second function mentioned is ABA’s ability to improve the plant’s potential for soaking up water from the soil. The third is ABA’s importance in protecting the cells from dehydrating, by activating the proteins that encode genes, to aid the cells against dehydration damage. Whereas, in bud dormancy (the fourth function mentioned), ABA helps to protect the apical meristem from drying out during winter by making it dormant. The fifth function, a little different than bud dormancy, looks at how ABA affects the process of seed dormancy and maturation, by keeping the seed to dormant until favorable conditions occur
