Plant hairs, called trichomes, protect plants from water loss and weather fluctuations and secrete plant oils as a defense mechanism against pests. Plant hairs do not develop into roots; this is a common misconception. The plant hormone Auxin initiates new root nodes or root primordium (primordia), which is the earliest stage of root development that you may find growing on non-root tissue, known as adventitious roots. Root primordium is a plant’s response to too much moisture in the air, over-watering, stress conditions such as flooding, or if the plant loses contact with its root system or is deprived of oxygen and nutrients. #fyp #foryoupage #foryou #tomatoes #gardenersoftiktok #plantsoftiktok #gardeningtips
