When drugs are swallowed, they may be broken down (metabolized) by enzymes and/or absorbed using. transporters in cells found in the small intestine. Grapefruit juice can cause problems with these enzymes. and transporters, causing too much or too little drug in the body. Some drugs, like statins used to lower cholesterol, are broken down by enzymes.
Monocots. Monocotyledonous leaves show a parallel venation and mostly are arrow or band-shaped. Stomata and other epidermal cells are almost always arranged in parallel arrays. These characterics are depicted in the photographs below of maize, papyrus and yucca.How monocotyle leaves develop is further explained in the section on monocot leaf formation.onocotyledonous leaves show a parallel venation and mostly are arrow or band-shaped. Stomata and other epidermal cells are almost always arranged in parallel arrays. These characterics are depicted in the photographs below of maize, papyrus and yucca.
Monocots include all grasses and glasslike plants, plus lilies, irises, amaryllises, and some other plant types. Usually, but not always, monocots possess parallel-veined leaves, as typified in the simple blade of fescue grass shown at the right. One example of a monocot which does not have parallel-veined leaves is the Trillium, several species of which are common in moist American forests.
