BIO203H5 Chapter Notes - Chapter 36: Starch, Cell Potency, Transpiration
Document Summary
Plants exhibit indeterminate growth that means they keep on growing throughout their lives. Plants use light energy (photons), co2 from air and water (electron source) from soil to make carbohydrates. Plants also use water to maintain normal pressure and volume by filling their cells. Plants also use nitrogen, potassium, magnesium and phosphorus to make macromolecules like nucleic acid, enzymes and phospholipids. Herbaceous plant (herb): seed plant that lacks wood and has short lived stem. Morphological diversity: root systems are diverse in shape and size. In prairie grassland ecosystems, grasses and herbaceous plants have root systems that are perennial (live for many years). If the aboveground portion dies in fire, winter or dry season, the plant can send up a new shoot system: root systems of prairies plants that live side by side can be very different. Prairies rose has a thick taproot that can store starch. Different plants have different root systems that penetrate the ground at different depths.
