Fruit trees, including temperate plants such as apples, pears and cherries, and tropical trees, such as mangoes and citrus, are angiosperms that rely on flowers to reproduce. The life cycle of these trees starts with a seed.

Germination

Seeds vary greatly in fruit trees, from the tiny apple seed to the large mango seed. The seed holds genetic material that, when conditions are good, begins to grow into a new tree.

Growth

The fruit tree seed sprouts, using stored starches to grow, and then sends out roots that collect water and nutrients. Stems and leaves also grow, providing sugars for the tree through photosynthesis. The fruit tree matures over time and then reproduces.

Reproduction

Fruit trees flower to reproduce. In each flower are male anthers that make sperm-laden pollen and the female pistil, consisting of the stigma at the tip, the style and ovary at the base.

Pollination

Insect pollinators move the pollen from the anthers to the stigma. Sperm cells enter the stigma, travel through the style and into the ovary to fertilize the ovules inside.

Seed Development

The fertilized ovules become seeds. The ovary grows into a modified seed pod, with a thick wall around the seed. This wall is full of sugars that taste sweet and are good to eat.

Dispersal

Once the fruit ripens, it may be eaten by humans or animals, often dropping the seeds to the ground. After contacting the soil, the seeds germinate to restart the life cycle of the fruit tree.
