Seed plants that produce fruits and flowers.
What are angiosperms?
The arrival of pollen on the female reproductive structure of a plant.
What is pollination?
A mature ovary.
What is a fruit?
Pollen grains are immature versions of this generation.
What is the male gametophyte?
Sporophyte
What is Diploid (2n)?
This accounts for the color and attractiveness of many flowers.
What are petals?
Three examples of pollinators.
What are bees, butterflies, and birds?
This protects and nourishes the embryo.
What is a seed?
The megaspore develops into this structure.
What is the female gametophyte (embryo sac)?
Gametophyte
What is Haploid (n)?
The tip of a flower's stamen.
What is the anther?
Pollen must arrive on this structure for pollination to occur.
What is the stigma?
The nutritive tissue found in angiosperm seeds.
What is endosperm?
Double fertilization produces these two products.
What are the zygote and triploid endosperm?
Megaspores
What is Haploid (n)?
The female reproductive organ of the plant.
What is the carpel (pistel)?
Three ways angiosperm seeds can be dispersed.
What are wind, water, and animals?
The structure that protects the flower bud.
What is the sepal?
This part of the flower produces pollen grains.
What are the anthers?
Ovule
What is Diploid (2n)?
The three parts of the carpel.
What are the stigma, style, and ovary (with ovules)?
True or False: Megaspores are formed in the stamen.
What is False?
This structure develops from a fertilized ovule.
What is a seed?
Pollen sac cells undergo this type of cell division to form microspores.
What is meiosis?
Endosperm
What is Triploid (3n)?
