Why do flowers bloom in spring?

Spring has sprung! It might not feel too warm but outdoors it’s starting to look a lot more spring-like. Flowers have bloomed and buds are appearing on the trees. But what is it about spring that makes the plant world come to life?

ImageLeaves breathe in air, take in sunlight and use water from the roots to make food for the plant. But this process also requires energy. In this instance, it is light energy provided by the sun. Therefore, the more sunlight there is, the more food the plant is able to produce. The more food it has, the more the plant grows. Because the days get longer in spring, the plant is exposed to more sunlight in these months. This means the plant grows more quickly than in winter when it is darker.

The springtime increase in temperature also causes an increase in growth. Like all biological activity, plant growth speeds up with heat, provided it does not become too hot. The rise in temperature at this time of year means that plants grow more quickly and seeds germinate. Now bring on some warmer weather!
