What is pollen?
Tiny structures that contain cells that will become male sperm cells
What is a seed?

What is a gymnosperm?
A seed plant that produces naked seeds
What is an angiosperm?
A plant that has flowers and fruit enclosed seed
What are the two types of angiosperms?
Monocot and dicot
What is a flower?
A flower is the reproductive structure of an angiosperm
A _____ protects and flowers and are often green
Sepal
A ______ is the colorful part of the flower
Petals
A _______ is the male reproductive part with the pollen
Stamen
What’s a filament?
Thin stalk of the stamen
What are two things inside a flower?
The sepal and the petal
What are the two things inside the stamen?
The filament and the Anther
The ______ is where the pollen is
Anther
What is the female reproductive part of the flower?
The pistils
What are the three things inside the pistils?
Stigma, style, and ovary
What’s a stigma?
The stick top portion of the pistil where the pollen sticks
The ______ is a slender tube leading from the stigma
Style
What’s an ovary?
A structure where the make cellls from the pollen join the female cells or egg from the female to make a seed
Where do the seeds form?
From a unfertilized female ovule
What’s an ovule?
An unfertilized female plant cell
What’s germination?
The sprouting of the embryo from the seed following dormancy, when the seed absorbs water, the embryo uses the stored food to begin to grow
What are the three steps of growth and development?
- Leaves form, photosynthesis starts
- Stem and roots grow
- Flowers appear if the plant has them
_______________ is the transfer of pollen from the make parts to the female parts of the plant
Pollination
What are ways seed dispersal happen?
Wind, water, animals, force from plant
What’s transpiration?
The process used by plants by which water is lost through the plant leaves
What’s respiration?
Exchange of gasses with your surroundings
Seed plants have ______________
Vascular tissue
What do seed plants use to reproduce?
Pollen and seeds
__________ are angiosperms that have only one seed leaf.
Monocots
______ produce seeds with two seed leaves.
Dicots
When does Germination begin?
When the seed absorbs water
