Flowering Plant Characteristics
-Reproductive structures found within plant
-dominant form of terrestrial life 80-90 million years ago.
-seeds enclosed in fruit
-includes all plants that produce a flower: trees, shrubs and herbaceous (non-woody) plants
Flowering Plant Trees
-often called broad leaved trees
-produce seeds inside fruit
-reproduce in a matter of months instead of years.
Most flowering plants use
-animals to transfer pollen form flower to flower
-Broad leaved trees, however, rely on the wind instead.
-Broad leaved trees with brightly colored flowers rely on bees and other animals to transfer pollen
Decidous Trees
-As nights get longer in autumn, biochemical changes in the tree trigger the droppoing of leaves

-All the recyclable parts of the leaf are removed and stored in the trunk and roots.
-this causes the leaves to turn orange, red, and gold.
Flowering Plant reproduction
-they usually have both male and female sexes
-structures that produce ovules
-accessory structures that produce female gamettes, known as eggs, within the ovules.
-when a pollen grain lands on a pistil, it releases its sperm cells
-attract insects
-produces male gametes known as sperm cells
-develops due to a sperm cell and an egg uniting to form a fertilized egg.

-The fertilized egg then develops into an embryo.
-have stamens that develop at different times than the pistils to prevent cross pollination.
-earliest flowerin plant; appeared in fossil record 130 million years ago.
More Magnolia characteristics
-has eggs that are clustered in the center, each protected by a green coat with a receptive spike on the top called a stigma.
-the eggs are placed on the stigma to be pollinated
How Magnolias avoid cross- pollination
-they have different maturation dates for stigma and stamen
-means that two species are evolving together.
-they do not decide to evolve together; they change according to what the other species is doing
More plant reproduction techniques
-Most plants wrap enticing flesh around their seeds, and animals such as monkeys or bats arrive to eat the fruits. The seeds are then carried away in the body of the animal. Later when the animal defecates, the seeds will be dispersed from the parent plant.
