The Science of How Plants Grow
As we’ve previously mentioned, plants grow according to three basic principles: photosynthesis, growth, and dormancy. These rules of nature are known as the science of how plants grow. When a plant reaches maturity, it produces its first leaves and develops its main stem. Once this happens, it’s called plant development.
Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, from germination to flowering. We'll cover five major types of plant hormones: auxin, gibberellin, cytokinin, ethylene, and abscisic acid. These hormones can work together or independently to influence plant growth. Auxin is involved in cell growth and cell expansion, so it is produced primarily in parts of the plant that are actively growing like the stem. Gibberellin causes some similar effects in plants as auxin, but it is a very different hormone. It promotes stem elongation between nodes on the stem. Cytokinins are produced in the root apical meristems and travel upward hitching a ride with water and traveling up the stem through the xylem. Cytokinins are like the fountain of youth in plants, as they delay senescence or the natural aging process that leads to death in plants. Ethylene is a plant hormone that affects ripening and rotting in plants, and it exists as a gas. Finally, abscisic acid is involved in the dormancy process, closing of stomata, and the formation of seeds.
How Plants Grow
Many of the main principles of how plants grow have been studied to death. Although it’s incredibly simple to grow most plants, it’s not easy to grow all of them. Fortunately, growing plants is fun and easy. In fact, most plants are easy to grow because they’re easy to care for and aren’t too hot to keep around. Why is that? Let’s try putting our knowledge about how plants grow in the real world first. How does a plant grow? There are three main processes you’ll see in plants, and they’re all important. First, let’s get our minds out of the gutter and get back to basics: photosynthesis. Photosynthesis is the process by which a plant produces its own nutrients, oxygen and nutrients for the other living things in the plant: the plant’s root system, the stem, leaves and the flower stalks. Once a plant produces its first few leaves, it’s called bud growth. After about a month, the leaves turn into flower stalks. The flower stalks are then called flowers, while the root system is called a stem. A few months after that, the plant reaches its peak production of seeds. Even though it’s almost insects and browsers’protocol time, the seeds are still present in abundance. Just as the leaves are being released into the environment, the flowers are also starting to bloom.
Conclusion
The science of how plants grow is not new. It’s been around for a long time, and it’s still effective in keeping plants from getting too hot or from getting too dry. The key is to make sure your plants are getting their nutrients and their needs from the right place, so they can stay Underworld-free.
