How the plant grow

28 Tháng Chín, 2018

All the plants around you start life as a seed. .

Seeds are usually fairly small. Some are even tiny. Despite their small size, though, seeds contain food and all the instructions necessary to sprout to life as a plant.

When seeds are planted, they first grow roots. Once these roots take hold, a small plant will begin to emerge and eventually break through the soil. When this happens, we say that the seed has sprouted. The scientific name for this process is germination.

As the plant grows and begins to make its own food from nutrients it takes from the soil, it will grow into a larger plant. The seed itself is like a survival package. It contains the food the seed needs while it is growing roots and forming into a small plant.

The three things plants need to grow are light, food and water. Light, whether from the Sun or an artificial light source (like a light bulb), gives the small plant the energy it needs to begin photosynthesisPhotosynthesis is the process the plant uses to convert light energy into food.

Like all living things, plants need water. Once a seed sends out roots, these roots will deliver water from the soil to the plant. As the plant grows and needs more water, roots will grow longer and stretch farther to find the necessary water in the soil.

When you get dry seeds at a gardening store, the seeds are dormant, which means they’re inactive. All it usually takes to wake them up, though, is just to add water. Whether you plant them in moist soil or simply wrap them in a moist paper towel, they will begin to come to life.
