Conjecture: We thought that a plants life cycle was birth, growth, and death.

Answer: After researching, we found that a plant's real life cycle is germination, then the plant grows, the plant grows flowers, the flower produces fruit, the fruit releases seeds, and finally, the plant dies.

                                                                                                                                                                                         The Steps of a Plant's life Cycle                                       

Germination is when the plant starts to grow from the seed, or is the sprouting of the seedling.  The stem, called the hypocotyl, pushes and emerges through the soil along with the seed leaves, called the cotyledons. A very common example of germination is when a plant usually sprouts from a seedling of angiosperm or gymnosperm.  Angiosperm is a type of vascular plant.  Gymnosperm is also a vascular plant, but is different from angiosperm.  Unlike seeds of angiosperm, seeds of gymnosperm are born in cones and are only visible when they become mature.     

Step two is The Plant Grows. The whole system of root continues to develop, securing the plant and anchoring it more into the ground, and finally the stem grows longer and continues to transport food between the roots and the leaves.

Stage three is The Plant Grows Flowers. The bud starts to produce flowers. Little sepals protect the bud before it opens. Then, eventually the bud opens and blossoms into beautiful and bright colored flowers, and the sepals look like little green leaves at the base of the flowers.

Stage four in a plant's life cycle is when it Produces Fruit. The fruits that plants produce can be placed into different groups, based on plant morphology and anatomy. Morphology deals with the study of the form and structure of organisms and their special features that their allowed by their structures. Anatomy is also the study of the structure of the plants. anyway, some of those groups are pome fruits, which include apples and pears, and stone fruits which include peaches, nectarines, apricots, plums and cherries.

Stage five in a plant's life cycle is when the plant Spreads Seeds. Some seeds spread when they are blown away by the wind. Others get stuck in the fur of animals when they're passing by and re-locate where ever the animal ends up. Water lilies depend on the water to carry the seeds away. Humans intentionally spread the seeds when they're planting in a garden. This stage helps keeps species of plants alive.

Finally, stage six is when the plant Dies.
