Smell is the most subtle of senses touched by spring. In spring there is the sweet fragrance of flowers, which is perhaps the first thing many think of. But my thoughts are drawn to subtler scents. In winter the sun is low and weak, giving little light and even less warmth.
Plants receive energy from light through a process of photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow.he makeup of a soil and its acidity determine the extent to which nutrients are available to plants. This pie grapgh informs us what is in the soil and how its composition is layed out. This pie graph was created on Chart Tool.
In the leaves of a plant is a substance called chlorophyll. Chlorophyll makes leaves green. It also traps the energy from the sun so the plant can use it. When plants take carbon dioxide from the air, they release oxygen. Animals use this oxygen to grow. We release carbon dioxide, which the plants use. Plants also need minerals from the soil to grow. Nitrogen helps them grow and make leaves. Phosphorus helps grow strong roots. Potassium helps the plant make fruit and it keeps them healthy. Plants need large amounts of nitrogen, phosphorus and potassium. The soil doesnât always have enough of these nutrients. Gardeners use fertilizer to give plants more nutrients. Fertilizers are sort of like vitamins for plants.
