Soil texture
--Coarse sand: LARGEST particles...Create a lot of air spaces between the particles but does not retain water very well
--Clay: Smallest particles....Fit together tightly so it retains water well but does not provide many air spaces
--Loams: most fertile soil types; consist of a mixture of sand (40%), silt (40%) and clay (20%)
-Clay, being the smallest particles, also represents the greatest amount of surface area and the particles are negatively charged
-The negatively charged clay particles bind tightly to positively charged nutrient mineral ions (Fe 2+, Mg 2+, Cu 2+, Ca 2+, Na 2+) and prevent them from leaching out of the soil during heavy rainfall
-Negatively charged ion nutrients tend to leach out of soil more quickly EX: NO-2, NO-3, and PO4
-The tightly bound cations are made available to plants through the process of cation exchange in which root hairs secrete acids and exchange hydrogen cations (H+) for other nutrient cations

transpirational pull cohesion tension theory

A function of the root
To hold the plant in the ground
3.7 Using seed food stores
-In a seedling the foods stores are kept in the 'Cotyletons'
-A seedling requires H2O, O2 and a high temperature
-Food stores are used to promote the growth of the "embryonic root" (radical) and the "embryonic shoot" (plumule)
-Nitrates phosphates and other minerals absorbed through root to promote growth of embryonic plant
-this continues until the plumule breaks through the surface and can start using Photosynthesis
Identify modifications of roots, stems and leaves for different functions: bulbs, stem tubers, storage roots and tendrils.
Bulbs: grown by leaf bases in some monocots as an underground organ for food storage. They can be identified because they have a series of leaf bases growing inside them, with central shoot apical meristem. It develops from an auxillary bud, and stores the food in its fleshy leaves (Example: Onion)
Stem tubers: grown from stems that go downwards in some dicots to form stem tubers. They store food and can be identified as stems, because although they are swollen their vascular bundles are arranged in a ring. (Example: Sweet Potato)
Storage roots: Some roots become swollen with their stores of food but can be identified as roots from their shape and vascular tissue in the centre (Example: Carrot)
Tendrils: Tendrils are outputs of leaves that will rotate upwards until they reach a solid surface, which they will latch onto. This allows the plant to grow upwards (Example: Sweet Pea)
