Primary growth
The tree growth from the branches (in length)
Primary growth refers to the increase in length of a plant, which occurs by cell division and elongation in the apical meristems found at the tips of roots and shoots.
In the root meristem, the cells divide to form new cells, which push the root cap downward and away from the meristem, allowing the root to penetrate the soil. As the cells continue to divide, elongation occurs in the region behind the meristem, causing the root to grow longer.
In the shoot meristem, the cells divide to form new stem cells, which differentiate into leaves, buds, and flowers. The apical meristem is responsible for the upward growth of the stem and the production of new branches.
Primary growth is crucial for plants, as it enables them to explore new environments and reach new sources of water and nutrients. Additionally, primary growth allows plants to increase their biomass, which is necessary for their survival and reproduction.
