5. Auxins are chemicals made by plants that play a part in many physiological roles. One auxin, indoleacetic acid (IAA), is a hormone produced in the meristem of plants. This
substance is transported down the plant's stem to encourage cell elongation and the
bending of the stem towards light. The production of IAA is working in conjunction with

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
