Tap Root. Plants with a tap root system have a large dominant central root where other lateral roots sprout. These lateral roots are called secondary roots. Examples of plants with taproot system are: sugar beet, parsnip, carrots, radish, dandelion and beetroot.
<span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. Gravity is used to transport the water molecules downwards. So, in a nutshell, if substances need to be transported from the top of the body downward, the force of gravity is used to transport the substances down. If substances need to be transported upwards, ATP, a coenzyme, is used to generate energy to transport the substance upwards</span>
What you have to bear in mind is to make the compound charged, in order that it will be soluble in water than in ether. You should make the pH basic for acid as in the salt compound in order to cause the acid to dissolve in the water layer.<span> </span>
