Many high mountain plants grow close to the ground in thick clumps to keep warm and out of the wind. In hot, dry desert areas, plants will have needles instead of leaves to help them retain water and keep predators away. Plants can adapt in their environment to protect and defend themselves against insects, animals, people, and even other plants. Some plants have developed special roots or hairs to get the water they need. 25 26 plants Some plants are parasites—they have huge sucking roots—and get their food and water from other plants.
Some areas may not receive any rain for months, or even years. But when rainfall does occur, a seemingly colorless, empty desert can suddenly bloom profusely as carpets of tiny plants appear in response to the rain. These plants grow quickly, producing flowers, which then produce a new crop of seeds. The entire life cycle—from seed to flower to seed—may be completed in just 10 days. The seeds can then lie dormant in the ground for years, awaiting the next significant rainfall event. For a few short days, the desert can be filled with beautiful, colored flowers.
At the tip of the stem, a little plantlet develops. It forms shoots and leaves and sends tiny, new roots into the ground to begin a new strawberry plant. This type of reproduction is called cloning. Although a huge quantity of seeds can be dispersed, only a few will actually successfully grow. The full potential is never reached. Only when soil moisture, temperature, and other conditions are right, will a seed begin to grow into a new plant. This process is called germination. When the seed soaks up water and swells, an embryo root is able to break out of the coating that surrounds the seed and, using energy from the food stored in the seed, to grow longer.
