Some different types of plant stems include herbaceous, ligneous, climbing, tubers, woody and aerial. Some specialized stems include buds, thorns and prickles.
Stems are designed to perform four functions on the plant, including support, transportation of fluids, storage of nutrients and the production of new living tissue. A stem is usually divided into nodes and internodes. The nodes are where the buds, leaves and flowers grow. The internodes are the spaces between each node, which is what most people refer to as the stem. Plant stems are green and have thin pipes called the xylem and phloem. These pipes provide nutrients to the plant and transport water.Learn More
Cacti produce their food through photosynthesis that occurs in their pads, which are modified stems. Evolution has modified their leaves into spines that provide shade for the pads and break up the wind to reduce evaporation through the skin of the stems.Full Answer >
Plants need water to grow because plants require internal water pressure to strengthen the stems and leaves, and plants need water to create energy. Water is also necessary for photosynthesis, which occurs in the plant's leaves with water from the stem.Full Answer >
