1. Germination: Tree seedlings start their life cycle when a seed germinates. Germination is the process by which a seed absorbs water and initiates growth, leading to the emergence of a tiny plantlet. The conditions required for germination vary between species but typically involve the right combination of moisture, oxygen, and appropriate temperature.

 

2. Cotyledons: The first leaves that emerge from a germinating seed are called cotyledons. Cotyledons provide the initial source of nutrition for the young seedling until it develops true leaves and starts performing photosynthesis.

 

3. True Leaves: After the cotyledons, the seedling develops its true leaves, which are typical of the species. These leaves are responsible for photosynthesis, a process through which the plant converts sunlight into energy and produces its own food.

 

4. Growth: As the seedling continues to grow, its stem elongates, and additional leaves develop. The root system also expands, anchoring the seedling in the soil and absorbing nutrients and water.

 

5. Environmental Factors: The growth and development of tree seedlings are influenced by various environmental factors, including sunlight, water availability, temperature, soil type, and nutrients. Different tree species have specific preferences and requirements for these factors.

 

6. Transplanting: Tree seedlings are often grown in nurseries before being transplanted to their final planting sites. This allows for better control of their early growth conditions and increases their chances of survival when transferred to a new environment.
