How do seed plants reproduce?
Flower Parts
Male Plant Partsstamen: male reproductive organ
anther: structure at the tip of a stamen that produces pollen
filament: a long tube that connects the anther to the base of the flower
Female Plant Partspistil: female reproductive organ
stigma: structure at the tip of a pistil where pollen can land
style: a long tube that connects the stigma to the base of the flower
ovary: contains ovules which become seeds after fertilization
Angiosperm life cycle8-square
Angiosperm Life Cycle
Pollen is produced in the anther. Pollen grains travel by wind, water, gravity, and animals from the anther to the stigma, where pollination occurs.
Pollen tube grows to reach egg in ovary. Sperm are released from the pollen tube and fertilize the egg.
A fertilized egg goes through mitosis to become a zygote. The ovule becomes a seed!
The ovary will develop into a fruit. The fruit will contain one or more seeds.
The seeds can grow into new, genetically related plants that produce flowers
Explain how flowering plants reproduce in your own words.
Fruits and SeedsThe ovary will develop into a fruit. The seeds can grow into new plants that produce flowers.
Flowers, Fruits and seeds chart
FruitsFruits help to 1.) protect seeds and 2.) disperse them
Seed dispersal: plants want to disperse seeds away from the parent plant

SignificanceNot only are flowering plants important for their beautiful colors and nice scents, angiosperms also produce food. Many animals, including humans, depend on flowering plants for fruits and vegetables.
